Just used your video. It's 35° here and my furnace kept kicking on and off after 4 seconds. Flame sensor was dirty. Cleaned it like you said and now we have heat again. My children will stay warm tonight. Thank you so much for these videos.
You rock, it's a pleasure to have found your podcast I appreciate your professional wisdom. Breaking the system down and easy to understand 👍. And thanks especially for all the internal links to your other videos I'll be sure to soak them in,💪
As an H.V.A.C Tech with 18 years experience your explanation is clear and precise you're spot on with your troubleshooting excellent video keep up the good work!!!!!
Man, you rock. Saved me hundreds of dollars over the past couple years with troubleshooting videos and how to fix them. No nonsense, just straight info, love it. Thanks for all the work you put into these videos!
@@monkeyfist1068 I’m pretty new so I wouldn’t charge much just to clean a dirty sensor that’s 65$ in 15 minutes but if I had to change it out and go to part store it would be some more money
Completely agree. Straightforward, no nonsense. He set up the failure condition to demonstrate each one. It's so helpful to understand what should happen when things aren't going well. This video is gold for a homeowner. Got my like and subscribe within the first 5 minutes.
Another big THANKS!! We woke up this morning, Christmas morning no less, to a freezing cold house. My husband had been out trying to decipher the installation manual, but me being a genius went straight to TH-cam and found you. Your #1 reason was indeed the answer! We scrubbed it off and are now nice and warm. So thanks again! Getting someone out here on Christmas Day would have been either impossible or cost us an arm/leg for something that took 5 minutes. You are wonderful for putting good out in the world like this, our own Christmas miracle. Hope you and yours are enjoying the day.
Watched your video while trying to figure out my heat. You helped get it working. Thank you. I have two babies and its getting cold out. you just saved us a ton!
Thank you! Did everything you said to do, furnace was up and running in 10 minutes. You are helping families that are on a budget. Simple fix that saved me money. Bless you for helping other.
I’m a general contractor and TH-cam has become a great tool for me. When you’re against the clock on a job you could get frustrated browsing useless videos but eventually you’ll find a gem like this one. Definitely subscribing so I could stay on top of your hvac videos. Thanks
Recently, I have begun viewing TH-cam videos for help on a variety of subjects but this is the first video that encouraged me to make a comment as well as subscribe to its channel because it saved my family time and money. This video explains typical furnace issues with relatable details all within 20 minutes. I did not have to fast-forward through the video and in fact, found it entertaining. After changing the filter with no results, my husband called out a service provider 2 days before Christmas and they were going to charge $265 just to come out, not including what they would have charged to repair and we could imagine the exploitative costs. The temperature in the house dropped to 53 degrees. I canceled the call and found this video. The furnace featured here is just like our furnace and step by step, I learned a lot and we may never have to call for service again after getting heat in the home again just in time to prepare for Christmas cooking, cleaning, and entertaining of planned as well as surprise guests! This guy is a genius who deserves an award and or television show. I will check out his other videos while I am on my 2-week winter break.
The safety switch was clutch for me! I spent 1k$ on the control board after the ac person said it was no good. It turns out the control board was OK; the safety switch was not engaging when the panels were closed in which the ac repair person either ignored or did not know to check. Thank you for saving me money! You're the man! I hope someone else will get used to this very detailed video! Cheers!
Being a lifelong learner who know little about these modern systems, I'm about to start watching everything you've posted to get an education on these furnaces. Glad to have found you.
@@SuperiorVideos12 my furnace went off, and @ 2 in the morning, it’s cold 🥶 went check out the thermostat and it’s down to zero..I called service 24 hrs but said they will come @ 10 in the morning.. Went open the furnace shut off the power and the gas valve.. I cleaned the igniter put it back..put switch on .. but the motor just humming..! I opened the other bottom door..the switch pop out.. I press the switch and few seconds it went for ignitions.. Lesson learned maybe switch just trip off like a circuit breaker..happy save my money 💰 just for a call 📞 cost 120$ plus part and service ..
Thank you so so much! Got home and our house was freezing cold (56F), saw your youtube and I tell you, you were my answered prayer! May God continue to bless you and your family!🙏🏽
Wish I had found your video sooner. $192 service call to diagnose and clean my flame sensor yesterday. You have now given me the knowledge and courage to try and fix it myself next time I have an issue. Excellent tutorial. Thank you for creating this video.
I’m not a tech and wish I had found this channel earlier. Over two winters I had to learn quickly how the furnace works. If anyone is a DIYer, the best way to fix your furnace is to learn the sequence of the furnace’s operation. Then you can troubleshoot the issues quickly. And be familiar with the furnace model to get parts. Great video! Thank you.
I had the same problem maybe 2 years ago and just now. This same video solved the problem. Saved me 100 dollars plus from a repairman. 2 thumbs up!!! Easy fix!!!
Very impressed with the ease and clarity in which this technician guides his audience through the unfamiliar workings of a furnace. Many thanks to you for creating the only instructional furmace repair video that truly helps!
Your video just saved me hundreds of dollars! After watching, I pulled the flame sensor out of my furnace, cleaned it with a steel wool pad, popped it back in, and the heat came back on. Took 10 minutes. Thank you!!!
I can’t thank you enough for help with your videos. I’m a single mom but pretty handy. My Dad passed & he always helped me troubleshoot my house issues. This is helping me save money I simply don’t have. God bless you, your family & friends and for taking the time to help others 💜🙏🏻
I just discovered your channel and just subscribed. I'm a retired contractor / handyman for 40 years, but never really got into HVAC. I always did maintenance on my own furnace for many years, but after I watched few of your videos, I've learned a couple of things from you. Keep up the good work
You rock! Professor Jay of the HVAC University! I have been dealing with furnace problems without understanding how they work for so many years. The most frequent problem I found is tenants replaced filter but failed to close the panel tightly, causing the door sensor to pop. Can't count how many service calls I've paid where the tech tells me, pushed the panel in, and furnace started working. Honorable mention: Tenant complained the furnace is vibrating so bad that it shook the whole house. Furnace is 30 years old, so the decision is to replace. When the old, trusty (Mars) furnace was removed and sitting on the ground, the problem was clear. A big Target heavy duty plastic bag inside the blower motor. (when they painted the house, the return grid was temporarily removed, the furnace was turned on because it was cold. Furnace sucked in the plastic bag.) I will be watching all of your videos!!!
This is a great video, thanks much. Just watched it for fun tonight after fixing my furnace today. Back in 2008 I replaced my furnace and A/C by myself. It was the rather new (at the time) 410 Freon so I did hire a couple of guys to come out and install the lineset. I saved several thousand dollars. I bought the A/C unit brand new on eBay and it is a 2 stage unit. The seller told me if I wanted to be able to take advantage of the 2 stage feature that I'd have to replace my furnace also. So I bought a two stage furnace and thermostat along with the A/C. Incidentally, the guys that came out to install the lineset told me I did a better job installing all my equipment than a guy who had worked as an installer for their company for 25 years! Anyway the other morning my wife and I both noticed at different times that the blower motor was unusually loud. I already had fixed the "bell end cap" of this motor years ago when the motor failed by replacing a $1.40 thermistor that had burned up and saved myself another $700 or so, (this motor costs $750 just for the part--that was absolutely the cheapest one I could find on the Internet yesterday)!!! Anyway, this morning I decided to take it apart and see if I could figure it out. It was very dirty due to my woodshop in the next room even though we replace the filter constantly. I removed the blower motor/squirrel cage/control board etc. I was in the midst of taking everything apart doing a very thorough cleaning when I came across a piece of paper in the squirrel cage within the fan blade! Turns out, it was the wiring diagram that is supposed to be pasted on the inside wall of the blower compartment. Over the years the glue had failed and it had gotten sucked into the fan which ended up causing the horrid noise we were experiencing! It actually had sounded like a loud truck running right outside of the house but there was No truck there! It's all better now and sounds beautiful, I really need to address the sawdust issue and calm down the constant intake and I'm sure everyone would be happier (including the furnace and A/C). Anyway, sorry for the long winded reply. I had to Vent, but this indeed was a very informative video!
Thank you immensely for this video. It serves as a great reminder of top items to check when experiencing issues with a furnace. We have been having fridged temperatures in Chicagoland the last couple of days, and my furnace has been working almost all the time to try and keep up. However, I noticed there would be periods when the furnace was not turning on, and the temperature inside would drop from 72 to 66 degrees. In my case, it appears the filter needed to be replaced, even though I replaced it last month. I have a higher MERV filter, which might help explain why it got clogged up quickly in a short span and most likely caused a lockout. Please keep up the great work. Providing information on HVAC to homeowners is very beneficial and will help many not be taken advantage of by dishonest HVAC companies.
This is the best video I've viewed on troubleshooting your furnace. My furnace went out last week during the winter storm. Of the 5 symptoms you went through, the blower motor, or maybe the flame sensor, describes my symptoms. Because, when my unit turns on, I can hear the usual humming sound for about a minute, then the furnace just shuts off. I called a heating & air guy & he said that I had a cracked heat exchanger & started quoting me a price to install a new unit. I'll get another guy to look test my blower motor first.
This video just saved me so much money. Number 1 was my issue, cleaned sensor and reinstalled. It's even warmer in home than before. Thank you so much. Keep up the great work bro!
I found your video after coming home to no heat and it was too late to call a repair man. I cleaned the flame sensor and it worked! Not only did you save this single mom a good amount of money, but my kids sleep warm tonight because of your advice. Thank you!!
I'm a heating technician for Town & Country Heating in Wahpeton North Dakota. I watched your video and it was great! The way you explained things was very clear so that anybody could understand it and get a basic knowledge of how a furnace works and what to look for when they're troubleshooting it. It would be nice if everybody watched it because we get service calls and go out to the house and someone says well I tried turning the switch off and on again which of course clears the codes and they never see the codes before they do that so it's a lot of troubleshooting for us once we get there. Plus if they don't know what they're doing and they watch this video at least he'll know what they shouldn't be doing. Anyway great job! I subscribe to your Channel
Brother, thank you for this video. After three days freezing my butt off every night, I found this video, went out tonight with Scotch in hand, cleaned the flame sensor finally I have heat at night! Very clear and easy to follow instructions
I watched this video and cleaned my flame sensor and that was the exact problem. Now we are warm again with no bill or wait for the heating company. Thank you!!
I recently purchased a new home, about 8 months ago. The furnace started making noises, like a bumping sound, and then would shut off. Found an extremely dirty air filter in the unit, and replaced control board. So many of the symptoms that were described matched my furnace’s ailments to the letter. I’m trying to learn more about the core of the systems in the house, to avoid excessive repair costs, and being able to troubleshoot issues before a more serious problem occurs. Now, when the furnace kicks on, I can listen to each step of the startup process, and know what it is doing, and how it should sound when it’s doing it. Thanks so much for providing these helpful and useful tutorials! Very much appreciated!
I was married for over 30 years to a mechanical engineer/ robotician. We built a home in 2000. I never saw him do anything to that furnace except changing the filter episodically. So, when I got the house in the divorce settlement in 2016, I kept doing what he used to do. But now I know better: I better get some education in all things that are traditionally labeled as "men's jobs" or I could lose this house. Thank you so much for your clear, concise and priceless and timeless videos. God bless.
Dude, you are a God to guy's like me. I'm real good with my hands but just not sure of what I don't know. I was charged $400 to replace an ignitor on the coldest night of the year, now I have two hand and can do it myself. You Rock, Bro!
It's 3am and our temp is down to 11.5. Freezing cold, so I had to find a way on how to fix my furnace issue. I found this video, and rushed to clean the flame sensor, and in 2 minutes, my furnace ran normally. Thank you so much !!!!
Jay you are the best! Just fixed the flame sensor and my furnace is working perfectly now. Can’t thank you enough for your help and your easy to follow instructions. Although the flame sensor was a bit of a pain in the rear end to get to, I cleaned it off and thank goodness it was the problem. Hope you and your family have a great thanksgiving. Take care😊
God bless you.. first time home owner...I know NOTHING lol... this super easy to follow vid saved my fiance and I from having to call out the professionals...I fixed the furnace Bae!! Thanks!
Wow! You just saved me several thousand dollars with your flame sensor cleaning instructions. Had a guy come check my furnace whose only suggestion was I needed to get a new furnace. Thanks!!
I love this guy! He has a video on this & that! I watched about 10 videos on troubleshooting my furnace & my thermostat. An amarture made a video which that's what he called himself not I. He showed me how to fix it in one minute & this video confirmed it & I learned not to call the HVAC specialist too quickly, thank you! I'll keep your videos close by! It's warm again!Your instructions are very clear as well thanks again! 😊
Thanks for your video! My issues were exactly what you described with a dirty flame sensor. Removed it, cleaned it and we have heat again. 10 minute DIY repair saved me $$$!
I have learned a lot from you.The way you explain everything is concise.I'm 67 and am always trying to learn for 2 reasons.1.Knowledge is POWER & 2. I've always hated paying someone to do something I can.Going to find your control board video.Thanx!
I was wondering why this was happening to my furnace and as usual I went to TH-cam and did exactly what he said. It worked like a charm. Saved me money because I contemplating calling a plumber. Thanks man!
Thank you! Flame Sensor was my problem. 1/4 inch socket was the same on mine and it save me time guessing. I can't believe how easy this fix was. Thank you for such an easy to follow format.
I want to express a big and sincere thank you for your videos and excellent explanations. It is because of you I was able to fix my furnace myself. It was indeed the flame sensor on my Lennox system. It was short cycling or turning on and off repeatedly. It was such an easy thing to replace and cost less than 50 bucks with shipping (it was an OEM part). I didn't want to go with the 7 dollar ones from amazon after looking at the reviews. It's hard to imagine that little piece was stopping the whole thing from working. I'm on Long Island so the winter hasn't been that cold this season so I took my time learning from your videos. I at first cleaned the sensor but that didn't do it. Anyway, thank you so very much!!!!
We have been watching this video nonstop for the past week now not because we have a problem with our air conditioner but because my autistic son is obsessed with air conditioners right now and this is the only video he loves. 😅
Thought I lost my furnace last night. Jumped on TH-cam while waiting for the technician and fixed it myself thanks to this video thank you soooooooo much. It was a dirty flame sensor you are a life saver!!!
Your ability to communicate clearly, even funny sometimes, and the wealth of vids you have up, and your extensive knowledge, have you every considered getting a series on Netflix? Seriously, why not?
Great video I was just able to clean off my igniter and now my home is back getting warmed. My wife was worried I was gonna mess it up but because of your video I was able to get the job done you’re the best
God bless you my friend! We now have a working heater just in time for the freezing weather! It was the flame sensor! God bless you and may you continue to prosper and be blessed!
You are truly one of the best in helping us all understand our systems. Your training videos are outstanding and I am sure have saved many of your DIY viewers a ton of money. Thank-You and keep up the good work on updating your videos.
I watched several of your videos to help me figure out why my furnace was blowing cold air. The video on the sequence of operation was very informative and helpful. I opened my furnace and look at the dirty filter. Before I did anything else, I changed the filter and called for heat (via my phone to my Nest thermostat). Watched the sequence of operation. It was just as you described. This time, the heat stayed on. Apparently my furnace was overheating because of a dirty filter. Thank you so much for your videos! I've subscribed and told several of my friends about your channel.
Another satisfied customer!! Thank you, thank you, and thank you even more!! I've resolved my dirty flame sensor issue by cleaning it as you so clearly lay out in your video! My sensor looks exactly like the example in your video so that made my experience even better! You've helped so me and so many others save a ton of money in unnecessary service calls! I'm a subscriber to your channel for life!! 🙂 Best Regards!
Fantastic! Straight to the point. I appreciate you not skipping over steps. Another channel just said "clean the sensor". You showed exactly HOW to do that without wasting a half hour of my (cold) life. Kudos!
High of -2, Low of -20. Furnace shutoff overnight. Woke up on a Saturday and my home was already at 53 degrees. Was stuck waiting on an answering service for the heating and A/C company and they never picked up in the time I was able to resolve with this video. THANK YOU THANK YOU THANK YOU!
God bless you! Thank you for making these videos, you are truly the best. The way you explain things is amazing, you saved us a lot of headaches, money, and precious time. I have been suffering from headaches from sleeping in the cold😢 THANK YOU!!!❤
Hey, just wanted to extend my gratitude for this video! It's -34 Celsius here and my furnace kept shutting off. I couldn't get any business to come take a look for over 24 hours so I decided to see if I could do something. Thanks to this vid I was able to get the flame sensor out and cleaned up which resolved the problem!
Your video just saved me sooooo much. Was about to call someone to check my furnace. Stumbled upon this video, took out the flame sensor, cleaned it and problem solved. Thank you for what you do.
Thank you Jay I ordered a service call then started watching your videos had it fixed so quick I cancled the call before the guy even started driving to me saved at least 100
Hi. Great video. My Sterling SC-60 propane furnace, in my garage, stopped working yesterday. It was a dirty flame sensor. Your Problem #1 described my issue exactly. I cleaned the probe with a gentle scotch pad. The furnace is now working properly and my garage is toasty warm. Thank you so much for the great community service you are providing with your clear and accurate videos. Cheers from Newfoundland, Canada.
Thank you! It is Christmas morning and our house was sitting at 58 deg. I tried to trouble shoot on my own but had no luck. Having gas heat, it was a dirty flame sensor just as you described. I cleaned it as you suggested and the furnace worked. Thanks again and Merry Christmas!
This is a follow-up to my original comment. Just as you said, my problem was the flame sensor that was dirty. Other than the fact that there is very little space in my attic, this was a very easy fix to clean the flame sensor. Thanks to your invaluable knowledge, I learned something and fixed it myself. You are appreciated.
I know me too! Now I’m 5 days into knowing it’s past the blower but still not finding it. I just found these other videos Jay made & will create a file so I don’t lose all this awesome information. It’s great to read about other grateful people! I’m so relieved!
@@misodinamosa the flame sensor is necessarily located close to the burners so it can detect the presence or fire. It’s only about 3 inches long and held in place by 1 or 2 screws. Google it and you may find a photo of one. Good luck.
Found your video last night as our furnace stopped running and couldn’t stay on for more than a minute. Just needed to clean the flame sensor and we had heat again! Thank you from someone living through a cold snap in Alberta with -35 windchill weather 🙌🏽
Your videos are clear and concise. Furnace was coming on and off , so I followed your “5 most likely problems” video and discovered that it was a dirty flame sensor.
Hey Jay, great video as always. I would add that sometimes you could have a bad blower motor capacitor. The motor will just sit there and hum but if you can safely spin the blower wheel and it takes off you have found a bad capacitor.
Furnace Counselor, I was shock about your being shocked. Thank you for taking the time to go over information you have covered. It may seem repetitive but very helpful. This one helped me again by showing me what parts I should have in case it goes..aka.spare new parts.
Thank you for watching and commenting Mr. Lennon! Hopefully this one helped explain it further. And I appreciate you making it all the way to the toothbrush ;)
Thank you very much. I just got home with everything I think I might be need to try to fix the problem by myself, my husband is out of town, he is extremely busy and right now we dealing with tons of stress so I wanna thank you very much for taking the time to share with all of us this helpful content, because now I'm sure I can fix my problem thanks to you, and save my husband money, and more importantly stress.
Thank you for sharing your expertise with such clarity! Our furnace worked intermittently. Sometimes, it started on the first ignition; sometimes, it needed two ignitions to kick on; other times, it stopped working totally. We followed your advice by cleaning the flame rod and the problem was solved. Thank you!!!
I unscrewed the flame sensor, but it was clean. Switched the filter and the flames remained on. Now my home is warm! Thanks for the help. You saved me a service call fee.
Awesome video and detailed trouble shooting. Saved me a service call. Furnace kept cycling with no start. Cleaned flame sensor and we have ignition. Tks.
Thanks for this great video! Very clear and easy to follow, even for someone like me who has never opened that panel before in my life. Turns out it was the filter, but the flame sensor got a good cleaning while I was in there anyway. Thank you!
I watched this video (and a few of your others) and fixed the problem just by wiggling the wires/connectors connected to the two pressure switches on my 20+ year old furnace! I wanted to avoid having an HVAC repair person visit given the pandemic so was able to do that with your excellent videos - thank you so much!
This is great. Just put your video into action by cleaning the flame sensor and sure enough that did it. Furnace is running smoothly now. Thank you so very much as I was starting to worry about the cost of getting my furnace fixed and right now I am on a very tight budget. Appreciate you.
Thank you so much for sharing. I am a DIY person when often possible and made useful notes from your video for later when, not if the High-E furnace fails again. With and without repairmen we have seen on our first and second High-E furnaces, a draft fan bearing (unreplaceable) failure for each, pressure sensor failure on one, circuit board failure on each, a burned-through heat exchanger on the first furnace and a dirty flame sensor on one. A circuit board replacement cost me $800 for two repairman trips. For all the money we spent on High-E furnaces I wish we had kept our old fashioned gas furnace that for nearly 40 years needed only a new fan belt, a limit control that cost little money for the part as a simple DIY task to replace and a flame sensor thermocouple. We also have a simple wall gas furnace at another location that has not failed since 1992 and still running fine now on 1-1-22. The old furnace might use more gas but the most important feature is that it did not fail in winter when are nearly all furnace failures are likely to appear. I would have paid nearly about the same for the extra gas instead of the repairs needed for the HIgh-E furnaces and would have skipped the anxiety while waiting for the repairman to show up.
You have an amazing channel. Long winded situation I hoped to get your thoughts on below. Furnace has worked fine since we bought our house last summer. Got the furnace and ducts cleaned yesterday (last serviced Oct 2019 by previous owners) noticed my temperature did not match the temperature it was set at on the thermostat just after the techs left. Woke up this morning freezing to see the temperature dropped even lower overnight (right in time for a mini snow storm). Furnace had been blowing cold air since the cleaning. They are closed today but I am waiting to give them an earful tomorrow morning... I think it's happening for one of two reasons: 1) They talked me into a "lifetime warranty microbe shield coated" metal filter that is now restricting airflow severely or 2) The BeneFect spray they added to the vents at the end got on the flame sensor or burners rather than spraying it above the A-coil. However, I cleaned the flame sensor myself this morning and it ran fine for two minutes but then the second I put the cover plate on it cuts out and the plate sucks in like you said in another video. I suspect it is the new filter causing the air restriction and high limit switch to trigger. Luckily I learnt so much from your videos I will be prepared tomorrow. Otherwise maybe my A-coil or burner motor are caked (after a cleaning though?) and can't handle the extra air restriction, or they messed with the gas pressure... I don't know but they did not ensure it was running properly prior to leaving and I think I'm justified asking for a return/refund on the filter and no charge for a follow up tune up. What do you think?
Thank you so much! It worked like a charm. Our furnace has been doing this for years. It was the flame sensor. I cleaned it. Now it’s working liking it hasn’t in years!
This is absolutely the most informative and concise video I've found. I simply cannot thank you enough for sharing this video. How much ridiculousness I've had to endure to get here. 🤦🏼♀️ Right now, I know my blower motor is fine because the AC was running no problem. I can hear a slight humming noise when I set my thermostat to heat but other than that, nothing happens. But now, I'm gonna see if I can't get a code from that light and have an experienced friend come over to help my troubleshoot. Winter is approaching quite quickly and I don't want to get stuck without heat. Especially because of my son. Thank you again so very much.
Our furnace stop heating suddenly and we decided to check out your video and make sure we understand what was wrong with the furnace. It turned out it was flame sensor. I follow your advice and cleaned it as you instructed. Thank you so much you just saved us money!
What a great presentation. VERY informative and well done. in cold weather it is taking 3 hours to return to set temperature. from 66 to 69. Now I can check some things. THANK YOU !
Thank you so much! Flame sensor strikes again! Last time you helped it was the plugged tube. This time I saw it was filling up again, so did a bit of preventive maintenance. You da man
Jay! Thank you so much for such a detailed video explaining all this! My problem was the dirty flame sensor and I fixed. I think there was 2 so I cleaned both. You da MAN!!!
Furnace was blowing strong but cool air and a technician couldn't come out for 3 days. Watched your video, went into the crawlspace (major fear of mine) and after watching it cycle and cleaning the flame sensor we have hot air again. You just saved me a couple hundred dollars on a tech and a couple days of running space heaters to get through til they could get here. Thank you so much!!!!

Just used your video. It's 35° here and my furnace kept kicking on and off after 4 seconds. Flame sensor was dirty. Cleaned it like you said and now we have heat again. My children will stay warm tonight. Thank you so much for these videos.
Lol homeowners 😂

You rock, it's a pleasure to have found your podcast I appreciate your professional wisdom. Breaking the system down and easy to understand 👍. And thanks especially for all the internal links to your other videos I'll be sure to soak them in,💪
Tenants throwing money away on a monthly basis 😇
As an H.V.A.C Tech with 18 years experience your explanation is clear and precise you're spot on with your troubleshooting excellent video keep up the good work!!!!!
Gotta appreciate this guy.. its not always about saving money, hes showing us how to keep our family warm when we need help

Best of the best !
Nice video
I'm a retired a/c tech. I follow your videos. They are the best clear and understanding. Straight to the point the way a teaching video should be.
Man, you rock. Saved me hundreds of dollars over the past couple years with troubleshooting videos and how to fix them. No nonsense, just straight info, love it. Thanks for all the work you put into these videos!
@@monkeyfist1068 I would of charged 65$ because that’s my hourly service fee and 65$ is pretty low I know techs that charge 135$ just to come out
@@monkeyfist1068 I’m pretty new so I wouldn’t charge much just to clean a dirty sensor that’s 65$ in 15 minutes but if I had to change it out and go to part store it would be some more money
Completely agree. Straightforward, no nonsense. He set up the failure condition to demonstrate each one. It's so helpful to understand what should happen when things aren't going well. This video is gold for a homeowner. Got my like and subscribe within the first 5 minutes.
Another big THANKS!! We woke up this morning, Christmas morning no less, to a freezing cold house. My husband had been out trying to decipher the installation manual, but me being a genius went straight to TH-cam and found you. Your #1 reason was indeed the answer! We scrubbed it off and are now nice and warm. So thanks again! Getting someone out here on Christmas Day would have been either impossible or cost us an arm/leg for something that took 5 minutes. You are wonderful for putting good out in the world like this, our own Christmas miracle. Hope you and yours are enjoying the day.
Watched your video while trying to figure out my heat. You helped get it working. Thank you. I have two babies and its getting cold out. you just saved us a ton!
Haha woke up this Christmas morning (2022) to the same issue! Weird as I changed the furnace filter 5 days ago
Thank you! Did everything you said to do, furnace was up and running in 10 minutes.
You are helping families that are on a budget. Simple fix that saved me money.
Bless you for helping other.
I’m a general contractor and TH-cam has become a great tool for me. When you’re against the clock on a job you could get frustrated browsing useless videos but eventually you’ll find a gem like this one. Definitely subscribing so I could stay on top of your hvac videos. Thanks
Recently, I have begun viewing TH-cam videos for help on a variety of subjects but this is the first video that encouraged me to make a comment as well as subscribe to its channel because it saved my family time and money. This video explains typical furnace issues with relatable details all within 20 minutes. I did not have to fast-forward through the video and in fact, found it entertaining. After changing the filter with no results, my husband called out a service provider 2 days before Christmas and they were going to charge $265 just to come out, not including what they would have charged to repair and we could imagine the exploitative costs. The temperature in the house dropped to 53 degrees. I canceled the call and found this video. The furnace featured here is just like our furnace and step by step, I learned a lot and we may never have to call for service again after getting heat in the home again just in time to prepare for Christmas cooking, cleaning, and entertaining of planned as well as surprise guests! This guy is a genius who deserves an award and or television show. I will check out his other videos while I am on my 2-week winter break.
This guy is great for the way he went step-by-step throughout the heating process, my man
The safety switch was clutch for me! I spent 1k$ on the control board after the ac person said it was no good. It turns out the control board was OK; the safety switch was not engaging when the panels were closed in which the ac repair person either ignored or did not know to check. Thank you for saving me money! You're the man!
I hope someone else will get used to this very detailed video!
Cheers!
Being a lifelong learner who know little about these modern systems, I'm about to start watching everything you've posted to get an education on these furnaces. Glad to have found you.
We have a new born baby and our furnace went out and it was freezing and this video saved us. Seriously; thank you so much.
Ours went out yesterday as well. It's been freezing here... it snowed can't get anyone out to look at it... 1yr old as well. Urgh.
@@SuperiorVideos12 my furnace went off, and @ 2 in the morning, it’s cold 🥶 went check out the thermostat and it’s down to zero..I called service 24 hrs but said they will come @ 10 in the morning..
Went open the furnace shut off the power and the gas valve..
I cleaned the igniter put it back..put switch on .. but the motor just humming..!
I opened the other bottom door..the switch pop out..
I press the switch and few seconds it went for ignitions..
Lesson learned maybe switch just trip off like a circuit breaker..happy save my money 💰 just for a call 📞 cost 120$ plus part and service ..
Always a good idea to have a few portable heaters as a backup.
Thank you so so much! Got home and our house was freezing cold (56F), saw your youtube and I tell you, you were my answered prayer! May God continue to bless you and your family!🙏🏽
Wish I had found your video sooner. $192 service call to diagnose and clean my flame sensor yesterday. You have now given me the knowledge and courage to try and fix it myself next time I have an issue. Excellent tutorial. Thank you for creating this video.
I’m not a tech and wish I had found this channel earlier. Over two winters I had to learn quickly how the furnace works. If anyone is a DIYer, the best way to fix your furnace is to learn the sequence of the furnace’s operation. Then you can troubleshoot the issues quickly. And be familiar with the furnace model to get parts. Great video! Thank you.
I had the same problem maybe 2 years ago and just now. This same video solved the problem. Saved me 100 dollars plus from a repairman. 2 thumbs up!!! Easy fix!!!
Very impressed with the ease and clarity in which this technician guides his audience through the unfamiliar workings of a furnace.
Many thanks to you for creating the only instructional furmace repair video that truly helps!
Your video just saved me hundreds of dollars! After watching, I pulled the flame sensor out of my furnace, cleaned it with a steel wool pad, popped it back in, and the heat came back on. Took 10 minutes. Thank you!!!
I can’t thank you enough for help with your videos. I’m a single mom but pretty handy. My Dad passed & he always helped me troubleshoot my house issues. This is helping me save money I simply don’t have. God bless you, your family & friends and for taking the time to help others 💜🙏🏻
I just discovered your channel and just subscribed. I'm a retired contractor / handyman for 40 years, but never really got into HVAC. I always did maintenance on my own furnace for many years, but after I watched few of your videos, I've learned a couple of things from you. Keep up the good work
You rock! Professor Jay of the HVAC University!
I have been dealing with furnace problems without understanding how they work for so many years.
The most frequent problem I found is tenants replaced filter but failed to close the panel tightly, causing the door sensor to pop.
Can't count how many service calls I've paid where the tech tells me, pushed the panel in, and furnace started working.
Honorable mention:
Tenant complained the furnace is vibrating so bad that it shook the whole house.
Furnace is 30 years old, so the decision is to replace.
When the old, trusty (Mars) furnace was removed and sitting on the ground, the problem was clear.
A big Target heavy duty plastic bag inside the blower motor.
(when they painted the house, the return grid was temporarily removed, the furnace was turned on because it was cold. Furnace sucked in the plastic bag.)
I will be watching all of your videos!!!
This is a great video, thanks much. Just watched it for fun tonight after fixing my furnace today. Back in 2008 I replaced my furnace and A/C by myself. It was the rather new (at the time) 410 Freon so I did hire a couple of guys to come out and install the lineset. I saved several thousand dollars. I bought the A/C unit brand new on eBay and it is a 2 stage unit. The seller told me if I wanted to be able to take advantage of the 2 stage feature that I'd have to replace my furnace also. So I bought a two stage furnace and thermostat along with the A/C. Incidentally, the guys that came out to install the lineset told me I did a better job installing all my equipment than a guy who had worked as an installer for their company for 25 years! Anyway the other morning my wife and I both noticed at different times that the blower motor was unusually loud. I already had fixed the "bell end cap" of this motor years ago when the motor failed by replacing a $1.40 thermistor that had burned up and saved myself another $700 or so, (this motor costs $750 just for the part--that was absolutely the cheapest one I could find on the Internet yesterday)!!! Anyway, this morning I decided to take it apart and see if I could figure it out. It was very dirty due to my woodshop in the next room even though we replace the filter constantly. I removed the blower motor/squirrel cage/control board etc. I was in the midst of taking everything apart doing a very thorough cleaning when I came across a piece of paper in the squirrel cage within the fan blade! Turns out, it was the wiring diagram that is supposed to be pasted on the inside wall of the blower compartment. Over the years the glue had failed and it had gotten sucked into the fan which ended up causing the horrid noise we were experiencing! It actually had sounded like a loud truck running right outside of the house but there was No truck there! It's all better now and sounds beautiful, I really need to address the sawdust issue and calm down the constant intake and I'm sure everyone would be happier (including the furnace and A/C). Anyway, sorry for the long winded reply. I had to Vent, but this indeed was a very informative video!
Thank you immensely for this video. It serves as a great reminder of top items to check when experiencing issues with a furnace. We have been having fridged temperatures in Chicagoland the last couple of days, and my furnace has been working almost all the time to try and keep up. However, I noticed there would be periods when the furnace was not turning on, and the temperature inside would drop from 72 to 66 degrees. In my case, it appears the filter needed to be replaced, even though I replaced it last month. I have a higher MERV filter, which might help explain why it got clogged up quickly in a short span and most likely caused a lockout. Please keep up the great work. Providing information on HVAC to homeowners is very beneficial and will help many not be taken advantage of by dishonest HVAC companies.
This is the best video I've viewed on troubleshooting your furnace. My furnace went out last week during the winter storm.
Of the 5 symptoms you went through, the blower motor, or maybe the flame sensor, describes my symptoms.
Because, when my unit turns on, I can hear the usual humming sound for about a minute, then the furnace just shuts off.
I called a heating & air guy & he said that I had a cracked heat exchanger & started quoting me a price to install a new unit.
I'll get another guy to look test my blower motor first.
This video just saved me so much money. Number 1 was my issue, cleaned sensor and reinstalled. It's even warmer in home than before. Thank you so much. Keep up the great work bro!
I found your video after coming home to no heat and it was too late to call a repair man. I cleaned the flame sensor and it worked! Not only did you save this single mom a good amount of money, but my kids sleep warm tonight because of your advice. Thank you!!
I second this!!! Little old retired lady here, you’ve saved me a couple times now, both time and especially $$$ and I sincerely appreciate you!
I'm a heating technician for Town & Country Heating in Wahpeton North Dakota. I watched your video and it was great! The way you explained things was very clear so that anybody could understand it and get a basic knowledge of how a furnace works and what to look for when they're troubleshooting it. It would be nice if everybody watched it because we get service calls and go out to the house and someone says well I tried turning the switch off and on again which of course clears the codes and they never see the codes before they do that so it's a lot of troubleshooting for us once we get there. Plus if they don't know what they're doing and they watch this video at least he'll know what they shouldn't be doing. Anyway great job! I subscribe to your Channel
Brother, thank you for this video. After three days freezing my butt off every night, I found this video, went out tonight with Scotch in hand, cleaned the flame sensor finally I have heat at night! Very clear and easy to follow instructions
I watched this video and cleaned my flame sensor and that was the exact problem. Now we are warm again with no bill or wait for the heating company. Thank you!!
I recently purchased a new home, about 8 months ago. The furnace started making noises, like a bumping sound, and then would shut off. Found an extremely dirty air filter in the unit, and replaced control board. So many of the symptoms that were described matched my furnace’s ailments to the letter. I’m trying to learn more about the core of the systems in the house, to avoid excessive repair costs, and being able to troubleshoot issues before a more serious problem occurs. Now, when the furnace kicks on, I can listen to each step of the startup process, and know what it is doing, and how it should sound when it’s doing it.
Thanks so much for providing these helpful and useful tutorials! Very much appreciated!
I was married for over 30 years to a mechanical engineer/ robotician. We built a home in 2000. I never saw him do anything to that furnace except changing the filter episodically. So, when I got the house in the divorce settlement in 2016, I kept doing what he used to do. But now I know better: I better get some education in all things that are traditionally labeled as "men's jobs" or I could lose this house. Thank you so much for your clear, concise and priceless and timeless videos. God bless.
This video is absolutely the best I have seen. Clear description of the problem, what to look for and how to resolve.
Dude, you are a God to guy's like me. I'm real good with my hands but just not sure of what I don't know. I was charged $400 to replace an ignitor on the coldest night of the year, now I have two hand and can do it myself. You Rock, Bro!
It's 3am and our temp is down to 11.5. Freezing cold, so I had to find a way on how to fix my furnace issue. I found this video, and rushed to clean the flame sensor, and in 2 minutes, my furnace ran normally. Thank you so much !!!!
Are we...the same person? 3:45 AM here haha and fixed it.
Jay you are the best! Just fixed the flame sensor and my furnace is working perfectly now. Can’t thank you enough for your help and your easy to follow instructions. Although the flame sensor was a bit of a pain in the rear end to get to, I cleaned it off and thank goodness it was the problem. Hope you and your family have a great thanksgiving. Take care😊
God bless you.. first time home owner...I know NOTHING lol... this super easy to follow vid saved my fiance and I from having to call out the professionals...I fixed the furnace Bae!! Thanks!
Wow! You just saved me several thousand dollars with your flame sensor cleaning instructions. Had a guy come check my furnace whose only suggestion was I needed to get a new furnace. Thanks!!
Sometimes with their labor costs and part replacement guesswork, it might be cheaper to get a new one. LOL
I love this guy! He has a video on this & that! I watched about 10 videos on troubleshooting my furnace & my thermostat. An amarture made a video which that's what he called himself not I. He showed me how to fix it in one minute & this video confirmed it & I learned not to call the HVAC specialist too quickly, thank you! I'll keep your videos close by! It's warm again!Your instructions are very clear as well thanks again! 😊
Thanks for your video! My issues were exactly what you described with a dirty flame sensor. Removed it, cleaned it and we have heat again. 10 minute DIY repair saved me $$$!
I have learned a lot from you.The way you explain everything is concise.I'm 67 and am always trying to learn for 2 reasons.1.Knowledge is POWER & 2. I've always hated paying someone to do something I can.Going to find your control board video.Thanx!
I was wondering why this was happening to my furnace and as usual I went to TH-cam and did exactly what he said. It worked like a charm. Saved me money because I contemplating calling a plumber. Thanks man!
Thank you! Flame Sensor was my problem. 1/4 inch socket was the same on mine and it save me time guessing. I can't believe how easy this fix was. Thank you for such an easy to follow format.
I want to express a big and sincere thank you for your videos and excellent explanations. It is because of you I was able to fix my furnace myself. It was indeed the flame sensor on my Lennox system. It was short cycling or turning on and off repeatedly. It was such an easy thing to replace and cost less than 50 bucks with shipping (it was an OEM part). I didn't want to go with the 7 dollar ones from amazon after looking at the reviews. It's hard to imagine that little piece was stopping the whole thing from working. I'm on Long Island so the winter hasn't been that cold this season so I took my time learning from your videos. I at first cleaned the sensor but that didn't do it. Anyway, thank you so very much!!!!
For me,You are the best HVAC teacher out there on yt!Thanks!
Thank you Jimmy! :)
Summer and winter here you are giving us sound advise, the gratitude and good feelings that you inspire are blessings. THANK YOU AGAIN.
We have been watching this video nonstop for the past week now not because we have a problem with our air conditioner but because my autistic son is obsessed with air conditioners right now and this is the only video he loves. 😅
Thought I lost my furnace last night. Jumped on TH-cam while waiting for the technician and fixed it myself thanks to this video thank you soooooooo much. It was a dirty flame sensor you are a life saver!!!
Your ability to communicate clearly, even funny sometimes, and the wealth of vids you have up, and your extensive knowledge, have you every considered getting a series on Netflix? Seriously, why not?
Great video I was just able to clean off my igniter and now my home is back getting warmed. My wife was worried I was gonna mess it up but because of your video I was able to get the job done you’re the best
God bless you my friend! We now have a working heater just in time for the freezing weather! It was the flame sensor! God bless you and may you continue to prosper and be blessed!

You are truly one of the best in helping us all understand our systems. Your training videos are outstanding and I am sure have saved many of your DIY viewers a ton of money. Thank-You and keep up the good work on updating your videos.
I watched several of your videos to help me figure out why my furnace was blowing cold air. The video on the sequence of operation was very informative and helpful. I opened my furnace and look at the dirty filter. Before I did anything else, I changed the filter and called for heat (via my phone to my Nest thermostat). Watched the sequence of operation. It was just as you described. This time, the heat stayed on. Apparently my furnace was overheating because of a dirty filter. Thank you so much for your videos! I've subscribed and told several of my friends about your channel.
Another satisfied customer!! Thank you, thank you, and thank you even more!! I've resolved my dirty flame sensor issue by cleaning it as you so clearly lay out in your video! My sensor looks exactly like the example in your video so that made my experience even better! You've helped so me and so many others save a ton of money in unnecessary service calls! I'm a subscriber to your channel for life!! 🙂 Best Regards!
Fantastic! Straight to the point. I appreciate you not skipping over steps. Another channel just said "clean the sensor". You showed exactly HOW to do that without wasting a half hour of my (cold) life. Kudos!
High of -2, Low of -20. Furnace shutoff overnight. Woke up on a Saturday and my home was already at 53 degrees. Was stuck waiting on an answering service for the heating and A/C company and they never picked up in the time I was able to resolve with this video. THANK YOU THANK YOU THANK YOU!
Excellent description of the sequence of events, and the symptoms of malfunctioning components.
God bless you! Thank you for making these videos, you are truly the best.
The way you explain things is amazing, you saved us a lot of headaches, money, and precious time.
I have been suffering from headaches from sleeping in the cold😢
THANK YOU!!!❤
Hey, just wanted to extend my gratitude for this video! It's -34 Celsius here and my furnace kept shutting off. I couldn't get any business to come take a look for over 24 hours so I decided to see if I could do something. Thanks to this vid I was able to get the flame sensor out and cleaned up which resolved the problem!
Your video just saved me sooooo much. Was about to call someone to check my furnace. Stumbled upon this video, took out the flame sensor, cleaned it and problem solved. Thank you for what you do.
you're a freaking hero. I'mma figure out what a service call would have cost me and base my donation on that, since you've solved my woes in
You just saved my life. It's 10 at night and 17 degree F outside. Thank you so much.
Thank you Jay I ordered a service call then started watching your videos had it fixed so quick I cancled the call before the guy even started driving to me saved at least 100
Hi. Great video. My Sterling SC-60 propane furnace, in my garage, stopped working yesterday. It was a dirty flame sensor. Your Problem #1 described my issue exactly. I cleaned the probe with a gentle scotch pad. The furnace is now working properly and my garage is toasty warm. Thank you so much for the great community service you are providing with your clear and accurate videos. Cheers from Newfoundland, Canada.
Thank you! It is Christmas morning and our house was sitting at 58 deg. I tried to trouble shoot on my own but had no luck. Having gas heat, it was a dirty flame sensor just as you described. I cleaned it as you suggested and the furnace worked. Thanks again and Merry Christmas!
This is a follow-up to my original comment. Just as you said, my problem was the flame sensor that was dirty. Other than the fact that there is very little space in my attic, this was a very easy fix to clean the flame sensor. Thanks to your invaluable knowledge, I learned something and fixed it myself. You are appreciated.
I know me too! Now I’m 5 days into knowing it’s past the blower but still not finding it. I just found these other videos Jay made & will create a file so I don’t lose all this awesome information. It’s great to read about other grateful people! I’m so relieved!
@@misodinamosa the flame sensor is necessarily located close to the burners so it can detect the presence or fire. It’s only about 3 inches long and held in place by 1 or 2 screws. Google it and you may find a photo of one. Good luck.
Found your video last night as our furnace stopped running and couldn’t stay on for more than a minute. Just needed to clean the flame sensor and we had heat again! Thank you from someone living through a cold snap in Alberta with -35 windchill weather 🙌🏽
Your videos are clear and concise. Furnace was coming on and off , so I followed your “5 most likely problems” video and discovered that it was a dirty flame sensor.
Hey Jay, great video as always. I would add that sometimes you could have a bad blower motor capacitor. The motor will just sit there and hum but if you can safely spin the blower wheel and it takes off you have found a bad capacitor.
Good to know I didn't even think of that
Thanks for mentioning this. Good to know.
Furnace Counselor, I was shock about your being shocked. Thank you for
taking the time to go over information you have covered. It may seem
repetitive but very helpful. This one helped me again by showing me what
parts I should have in case it goes..aka.spare new parts.
Thank you for watching and commenting Mr. Lennon! Hopefully this one helped explain it further. And I appreciate you making it all the way to the toothbrush ;)
Thank you very much. I just got home with everything I think I might be need to try to fix the problem by myself, my husband is out of town, he is extremely busy and right now we dealing with tons of stress so I wanna thank you very much for taking the time to share with all of us this helpful content, because now I'm sure I can fix my problem thanks to you, and save my husband money, and more importantly stress.
Thank you for sharing your expertise with such clarity! Our furnace worked intermittently. Sometimes, it started on the first ignition; sometimes, it needed two ignitions to kick on; other times, it stopped working totally. We followed your advice by cleaning the flame rod and the problem was solved. Thank you!!!
Thank you!! I just cleaned my flame sensor and we now have heat. Simple fix thanks to your video!!
This video is a godsend. Literally saved me money, time and worry. Thank you.
I unscrewed the flame sensor, but it was clean. Switched the filter and the flames remained on. Now my home is warm! Thanks for the help. You saved me a service call fee.
Thanks so much! Giving the inducer motor a helping hand is all it took to get my furnace running again.
Awesome video and detailed trouble shooting. Saved me a service call. Furnace kept cycling with no start. Cleaned flame sensor and we have ignition. Tks.
Thanks for this great video! Very clear and easy to follow, even for someone like me who has never opened that panel before in my life. Turns out it was the filter, but the flame sensor got a good cleaning while I was in there anyway. Thank you!
You just saved me money on a service technician. I just cleaned my flame sensor and it fixed the problem. Thanks a bunch bro!
Dude. I went to, but couldn't finish hvac school. I actually learned more here. Thanks
I watched this video (and a few of your others) and fixed the problem just by wiggling the wires/connectors connected to the two pressure switches on my 20+ year old furnace! I wanted to avoid having an HVAC repair person visit given the pandemic so was able to do that with your excellent videos - thank you so much!
This is great. Just put your video into action by cleaning the flame sensor and sure enough that did it. Furnace is running smoothly now. Thank you so very much as I was starting to worry about the cost of getting my furnace fixed and right now I am on a very tight budget. Appreciate you.
Thank you so much for sharing. I am a DIY person when often possible and made useful notes from your video for later when, not if the High-E furnace fails again. With and without repairmen we have seen on our first and second High-E furnaces, a draft fan bearing (unreplaceable) failure for each, pressure sensor failure on one, circuit board failure on each, a burned-through heat exchanger on the first furnace and a dirty flame sensor on one. A circuit board replacement cost me $800 for two repairman trips.
For all the money we spent on High-E furnaces I wish we had kept our old fashioned gas furnace that for nearly 40 years needed only a new fan belt, a limit control that cost little money for the part as a simple DIY task to replace and a flame sensor thermocouple. We also have a simple wall gas furnace at another location that has not failed since 1992 and still running fine now on 1-1-22. The old furnace might use more gas but the most important feature is that it did not fail in winter when are nearly all furnace failures are likely to appear. I would have paid nearly about the same for the extra gas instead of the repairs needed for the HIgh-E furnaces and would have skipped the anxiety while waiting for the repairman to show up.
You have an amazing channel. Long winded situation I hoped to get your thoughts on below. Furnace has worked fine since we bought our house last summer. Got the furnace and ducts cleaned yesterday (last serviced Oct 2019 by previous owners) noticed my temperature did not match the temperature it was set at on the thermostat just after the techs left. Woke up this morning freezing to see the temperature dropped even lower overnight (right in time for a mini snow storm). Furnace had been blowing cold air since the cleaning. They are closed today but I am waiting to give them an earful tomorrow morning... I think it's happening for one of two reasons: 1) They talked me into a "lifetime warranty microbe shield coated" metal filter that is now restricting airflow severely or 2) The BeneFect spray they added to the vents at the end got on the flame sensor or burners rather than spraying it above the A-coil. However, I cleaned the flame sensor myself this morning and it ran fine for two minutes but then the second I put the cover plate on it cuts out and the plate sucks in like you said in another video. I suspect it is the new filter causing the air restriction and high limit switch to trigger. Luckily I learnt so much from your videos I will be prepared tomorrow. Otherwise maybe my A-coil or burner motor are caked (after a cleaning though?) and can't handle the extra air restriction, or they messed with the gas pressure... I don't know but they did not ensure it was running properly prior to leaving and I think I'm justified asking for a return/refund on the filter and no charge for a follow up tune up. What do you think?
That was the flame sensor!
You just saved us $800-$900 dollars, thanks a lot!
Merry Christmas!
Good show, nicely done, as a retired Stationary Engineer , I can tell you really know what you are talking about.
Thank you so much! It worked like a charm. Our furnace has been doing this for years. It was the flame sensor. I cleaned it. Now it’s working liking it hasn’t in years!
I repaired my furnace because of you! Thank you, saved $200
Very detailed with clear instructions on troubleshooting. Your videos are outstanding and very much appreciated. Thank you
This is absolutely the most informative and concise video I've found. I simply cannot thank you enough for sharing this video. How much ridiculousness I've had to endure to get here. 🤦🏼♀️ Right now, I know my blower motor is fine because the AC was running no problem. I can hear a slight humming noise when I set my thermostat to heat but other than that, nothing happens. But now, I'm gonna see if I can't get a code from that light and have an experienced friend come over to help my troubleshoot. Winter is approaching quite quickly and I don't want to get stuck without heat. Especially because of my son. Thank you again so very much.
Our furnace stop heating suddenly and we decided to check out your video and make sure we understand what was wrong with the furnace. It turned out it was flame sensor. I follow your advice and cleaned it as you instructed. Thank you so much you just saved us money!
What a great presentation. VERY informative and well done. in cold weather it is taking 3 hours to return to set temperature. from 66 to 69. Now I can check some things. THANK YOU !
This Guy is dropping knowledge on us like end of the world is coming up 👍🏻👍🏻👍🏻
It is when you have to buy a new furnace. The furnace isnt much , but the labor is twice as much
Very helpful video!!! Not to fast, not to slow and very detailed! Thank you for sharing!
Thank you so much! Flame sensor strikes again! Last time you helped it was the plugged tube. This time I saw it was filling up again, so did a bit of preventive maintenance. You da man
Thank you man you really saved my fiance and I today with these videos I was able to reboot our furnace. You Rock! Happy Holidays!
Jay! Thank you so much for such a detailed video explaining all this! My problem was the dirty flame sensor and I fixed. I think there was 2 so I cleaned both. You da MAN!!!
Are you sure you had 2? One was probably a hot surface igniter
@@mccool131 no need to clean two, typically there is one flame sensor and one is the igniter. DO NOT TOUCH YOUR IGNITOR. It is very fragile.
Furnace was blowing strong but cool air and a technician couldn't come out for 3 days. Watched your video, went into the crawlspace (major fear of mine) and after watching it cycle and cleaning the flame sensor we have hot air again. You just saved me a couple hundred dollars on a tech and a couple days of running space heaters to get through til they could get here. Thank you so much!!!!
It was a dirty flame sensor for me my friend. Truly appreciate this video. I’m from Canada and winter right now is starting to go crazy.
