@@mavericktorch1619 Thanks for watching. If your furnace gives you multiple codes, and none of the switches are faulty then it could be a problem with the wire connects or a problem with the control board itself. The control board is pretty simple to replace but is usually a non-refundable part. You can see how to replace it here: th-cam.com/video/4SY8lRl8HV0/w-d-xo.html
Great video had this issue vacuumed the vent out put and while doing so I started it up and it stayed on...thanks for a clear and concise video my friend you have a sub for life no doubt.
Great video. One thing about the inducer blower. We had an issue with the inducer coming on, then shutting back down. Eventually things kicked in later on and were normal. Then it happened again, so I called an HVAC specialist, but by the time her came, the furnace was running normally. So more background, this obviously is in the winter, and we were getting cold spells. I was also setting the furnace very low at night (13ºC). I then realized that any condensation that perhaps built up during the night, as the furnace was off for a good 10 hours, was obstructing the flow of air from the roof inlet. Once I set the low temperate to 19ºC, the issue never reoccured. The furnace does cycle on once or twice during the night, but by morning, it'll start up right away. Came here because I think I have an issue with the flame sensor (it always comes on and stays on, but after 1 or 2 tries) -- but unsure if it's the Nest doing this to conserve energy.
Imagine this: 2 a.m. and -20° outside w furnace turning on and off... 3 small kids, mom and I freezing. Watched like 10 other videos and nothing helped. Watched this one and voila! The vent was blocked w powdery snow. THANK YOU SO MUCH. And thanks for speaking slowly and clear, I was able to follow you without any problem.

Sorry I forgot to mention sears installed our furnace 7 years ago , anytime I tried to watch the installer , he & his partner stopped working . They were talking spanish & I could not understand them , but as soon as I left them alone they start to work . As a 45 years mechanic I,ve never mind people watching me , but anyhow I call same man on thursday , he told me he comes monday which is today . I am reading & watching U & the others , so when the man come , he does not tell me nonsense . I thank U for your respond . GOD SPEED ❤

I’ve had a problem with my furnace for a while now and I thought I had tried everything. Was about to hire out a professional to come and check it out but decided to try and clean the flame sensor. I think that was the problem. 2 minute fix that probably saved me $100+. Thank you SO MUCH!!!
Your video was very helpful in troubleshooting. The clear troubleshooting for each phase of operation made it easy to find the flame sensor was at fault. Thankfully managed to fix it on a dangerously cold night of -27°C (-17°F) My furnace would occasionally run normally. But every few hours, it would attempt to light 3 times, and shut off. I could hear the burners ignite for about 3 seconds, then they would shut off. Investigated the flame sensor. It was clean, but was loose and not close enough to the flame. Tightened the screw and re-adjusted so was in the flame path, and now it's working perfectly. Although you didn't mention that particular issue in the video, it still helped me narrow it down.
Thanks for watching. We're glad that the video helped you get your furnace working again after such a cold night. You are right that this video didn't go into all the details on the flame sensor. The flame sensor is actually just a rod that sits in the flame. It doesn't sense heat, it completes a circuit from the control board, through the flame sensor, through the flame to the burner or heat exhanger, and returns through the ground wire. The position of the flame sensor, a dirty flame sensor or a carbon buildup on the burner can all prevent this low voltage DC circuit from being completed. Hope this helps provide a little more context!
My furnace was igniting then shutting off then on again continuous with no heat. The sensor had very little corrosion but I cleaned it and reinstalled and works fine again. I appreciate your time in making this video. Saved me $$$ Thanks.
Thank you Carol for your kind words! It means a lot to know that our videos are helping to inspire people! We really have made an effort to try to help people gain more knowledge so that they can do the repair themselves or just have a better understanding for when they communicate with a professional. All the best to you!

Excellent video! I found that after remodeling work, even with the system off, all of my sensors got dirty. This video narrowed it down to the main culprit, but gave me the confidence to explore my system further and check/clean every sensor carefully. Just took a tiny bit of dust to throw some of them off.
Thank you, we're just glad that the video helped you out! The flame sensor is particularly sensitive to a buildup of dust or carbon as it relies on a small DC current to travel from the control board, through ions in the flame through ground. This is how it proves that a flame is present. The flame sensor is nothing but a small metal rod. Nothing special about it.
This should be the first line of attack when you have a "Short Cycling Furnace Problem". I almost gave up after cleaning the furnace and checking the Nest thermostat, fan limiter, limit switches, replacing the air filter and fan capacitor, etc... I was ready to call the HVAC professional when I decided to give Google another try, I entered "Why does my furnace keep turning on and off", and I found this section (3:13) in your instruction exciting, (holy sugar!) cleaning the burners and flame sensor monitors are the solutions to my problem after all. It took me a day and a half to figure it out, I lost half of my hair scratching my head, thank you very much for your help, this post really made my day...
Thank you for sharing! We are just glad that people are finding these videos helpful and when it comes to the flame sensor, it is the root of many furnace issues for a good number of people. Cheers!
Great video. It just confirmed my last fix is the right one. I had already been through cleaning the flame sensor, took the burners out and cleaned them, and thoroughly cleaned everything inside that I could, replaced the limit switches and the furnace would still decide to not ignite on occasion. I took the pressure switch tubing off and some water in there. After draining that and blowing it out good it has fired up without a hitch.
THANK YOU! It’s 16 degrees on a Friday night here and my heater pilot would not stay on. It didn’t match your video exactly because the pilot would continuously light and go off within a couple seconds but the fan was blowing the entire time. Regardless, I cleaned the flame sensor (which barely looked tarnished) and it immediately fixed the problem. I cannot thank you enough!!!!! ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
You're welcome, we're just happy to help! It could be an issue with the thermocouple, so it might re-appear. th-cam.com/video/3EKbSiAJyiI/w-d-xo.html Also if you have a multimeter you can test the thermocouple voltage to see if it is producing enough voltage to keep the pilot flame lit. If you have a spark ignition then your furnace might work slightly different than the thermocouple example as before. You can test the voltage similar to the steps in this video: th-cam.com/video/Mx6rZA9Yxv4/w-d-xo.html
Great Video.. 4 am.. Zero degrees outside. House temp 55 degrees.. Furnace short cycling. Watched this Video.. Cleaned flame sensor.. Took care of problem.. One of the best video's for trouble shooting .. Thank You !!!! Happy Wife ,,Happy LIfe !!
Thank you! I think you'll love these videos as well, we have a whole playlist showing "how it works" all with detailed graphics: th-cam.com/play/PLCo9SMjkdWBxWwrWCmzvRMSi2kLo9bGdp.html
By far one of the best DIY videos. I'm very handy and have been fixing my own appliances etc for years, including putting a new circuit board on my furnace a few years back. Is was having short cycle issues for the past 2 years and have done EVERYTHING mentioned in your video except for ONE thing! No other video or website that I've come across has talked about or mentioned the LIMIT SWITCH!! Thank you and wish me luck!!
Thank you, we're glad that you found the video helpful! We really try to make all of our tutorials informative especially with graphics and concise information. Best of luck with the repair!
UPDATE!! I first want to say that this is the ONLY DIY video that mentioned the LIMIT SWITCH as a possibility. Well I'm here to update everyone and can now report that the LIMIT SWITCH was EXACTLY my problem. I had the Short Cycle problem for a couple of years and had done EVERYTHING to correct it myself. Well I finally heard this info and purchased a NEW limit switch online for $24..PROBLEM SOLVED!! I want to thank AMRE Supply for these videos and will now subscribe to their channel! Thank You AMRE, you guys are lifesavers!!
I had a problem and my furnace kept switching off after few minutes of heating in repeated cycles and that was the last issue you walked through. I had to change the filter which is just a month old and it fixed the problem. Can't understand how a one month old filter can cause a trouble but the solution you provided was spot on. Your videos are phenomenal and well explained to the point. A big thank you!
Thanks for watching, we're glad that you found the video helpful. Was the MERV rating different on any of the filters? If a filter was a higher MERV rating and more restrictive than the others, then it can cause the heat exchanger to overheat.
My experience: buy the least restrictive filter They are cheap 1.50 - 3.00 $ each and replace often especially if you got pets who shed inside the house .plus more efficient at moving the cool air in summer

@@AmreSupply Yes it was. At 5pm on a Saturday of a long weekend in February, it wasn't a happy discovery. But your excellent video had us up and running in no time. Thanks again (and subscribed)!
This is a great video very detailed but I’d like to add something to this. If the heater keeps shutting down and you have done all this! Check your condensate pump line. It might be frozen if it is up in the attic and it’s like 6 degrees outside. So if your condensation pump is hooked to your heater it will shut it down as well.
Well done and very educational. I hesitantly called a guy out who started immediately with the 'I hope it's not the heat exchanger,' for which I'd throw him out. He was pretty good at testing everything methodically, as an engineer though I was questioning things - enough for me to realize he didn't get it and just wanted to throw parts at it. These things are not rocket science so I'm sick of these technicians who come out with more stories than Shakespeare. I learned more from you in 5 minutes. I already suspected he flame sensor, but will review limit switch as well. The 'tech' wanted to replace the circuit board for $1800! I found them online for under $100 (btw, that is what I used to do so I don't need his warning of electrocution or 'every year the fire departments find people in attics' (he said that!). The other annoying thing is finding info in materials or on company's website - everything just refers you to other criminals, I mean 'techs.'
Thank you for sharing your experience and we're glad that you found the video helpful. This was one of our goals with the furnace series is to help homeowners gain a bit of knowledge. People go through the same stress with vehicle repairs, a little bit of knowledge can help prevent a mechanic from doing unnecessary work or over charging for a simple repair. Also $1800 is highway robbery for a control board. With the power disconnected these boards are very simple to replace.
@@AmreSupply Yep, you will do far better being transparent and honest than these hacks out there trying to get rich off every single call. Good branding! I've not swapped the board because I've been doubtful and prefer to review the other items like you showed. Business is so easy, but there are still these old school clowns hanging on to ideas that 'people don't know' (tell 'em it's danegerous.'), they'll be gone soon enough, I hope.
I called a guy which costed $180 came over, and only cleaned my furnace, then suggested me to replace the furnace, but didn't solve my issue. I cleaned they flaming rod myself and now it worked for about 3 months. but now, the furnace works only when the cover is opened, as soon as I put the cover on, it stops, even with the filter took off. Could you help suggest what's the issue? thanks
@@shw4083 They suck, as do plumbers, AC techs, water heater and appliance people, someone is teaching them bad habits - how about honest work for honest pay? Crooks.
@@shw4083did you ever figure this out? My error code is reading limit switch, if I have both doors on it will run for 5 minutes then shut off then cycle again a few more times before lockout. If I leave the flame door off it will just keep running without shutting off.
You mentioned in the beginning of this video the different kinds of safety switches - pressure switch, flame sensor, flame rollout switch, and the limit switch and what they do. I was wondering what the flame rollout switch does and the signs of when to replace it? Your videos are awesome and I love this channel. Thanks for all the education!
Thank you, we're quite glad that you're finding the videos helpful! The flame rollout switch monitors the burners, if there is an airflow issue and the flames are "rolling" out the front of the burner, then the switch will disconnect power. If you notice a lot of carbon buildup around the front or and the switch then that indicates a flame rollout issue, and that will need to be investigated further. If there are no signs of a flame rollout, but the switch is having issues, then it could be a faulty switch. The flame rollout switch should have continuity at room temperature. If it doesn't then it's faulty and should be replaced. This kind of failure is not that common though.
You're welcome Rj, thanks for watching! While you're at it its a good idea to have an extra furnace ignitor on hand as a backup. Ignitors are a common point of failure as well.
at first I was sure the problem was going to be the igniter but after watching that video and allowing the furnace to try starting with the front panel off I could see that the igniter was working fine and I had flame for several seconds before it would shut off. I tried checking the flame sensor and wasnt too hopeful because it barely looked dirty. a quick clean with some fine sand paper, put it back in, turned the system on and it's running perfect! I also think the electrical connection may have been loose so made sure that was tight. thank you so much for this great helpful video! saved me at least $150 for a service call and who knows if they would have tried to sell me something I didnt actually need. I hope this business model is working for AMRE. I was totally ready to order parts from you guys if I needed them.
Thank you for sharing your experience, we're glad the video helped you out! You are right a loose connection, corrosion on a terminal, or a frayed or broken wire can cause the same issues as a dirty flame sensor. Overall AMRE has come a long way in 50 years we're fortunate to be able to help people out with these videos! Thank you for the support and we'll still be around next time one of your appliances or fixtures needs a new part! Cheers
Thanks AMRE and this video. My furnace keeps turning on, ignitor would ignite gas then off for three cycles. It's a Lennox G40UH. The diagnostic lights indicate bad ignitor. So replaced ignitor. Still the same. Then cracked open a beer and watched this video. Symptoms point to bad flame sensor in second part of video. So I cleaned the flame sensor as instructed. Lo and behold, it worked.

Hi AMRE! wanted to thank you for this great video. i've never worked on my furnace before (outside of filter changes) and within minutes i had my issue identified (faulty temp sensor). you saved me when i was in a pinch!
Had the exact issue you described with the shuts off after ignition. Per your directions I cleaned up the flame sensor and it turned on immediately. Thanks!
thanks for information, Vance you just save me at least one hundred, i did remove de flame detector clean it, and put it back ...worked, thanks from new jersey
Another potential issue that could cause furnace turning itself off after running (with gas on) for a short time is that the outdoor exhaust and intake ports/pipes were installed incorrectly. If both pipes have openings (outside) next to each other, such as both facing down, then the intake may be sucking in the exhaust gas, causing a lack of fresh air/oxygen for combustion. Fixed easily by making one pipe face out and other facing down. Though illustrated clearly in instruction manuals, some installers don't do this right.

@@AmreSupply It was the flame sensor on my really old but really reliable Goodman furnace. I did exactly as stated in the video and took it out and cleaned it with some steel wool, and voila! Household heat!
Hi I have question my igniter turn on three times then my fire starts and my light is blinking 3 short and 4 long ones once the fire starts then stay lit everything else is normal the only problem is my igniter light up 3 * then I'll leave my gas releases them the fire and I change all three senses what do you think the problem is
Best to check what that code is. The code is different for each model so check your furnace manual or the diagram which might be on the back of the furnace door. Also if the furnace ignites but doesn't stay lit or takes several times to stay lit, then it might be worth cleaning or replacing the flame sensor. That would be the first place to start.
Im getting three short and for long(34) bryant. Model # 310aav036070adja. Ignitor Light Up 3 times and shut off with the machine on then only gas and fires up
@@gomasmas5727 The 34 code for that model is a "Ignition Proving Failure" what you are seeing is the furnace try to light 3 times then shut down and lockout until trying again.

Thank you this video helped me get my furnace going it was my flame sensor I pulled it out clean it off on my jeans and stuck it back in and its working great.
Looks like I need a new limit switch, too bad it’s in the single digits here on Xmas eve and will have to wait a few days, but in the mean time I’ll check continuity on the limit switch to be certain Time to fire up the gas logs! Thanks Vance
This video is very helpful, thank you! I do find my furnace shuts off due to water in the pressure switch tube. But after clearing the water for a week, I got water in my tube again. This happens multiple times this year. Do you have any recommendation for this issue?
Thanks for watching. Check the condensate tube and make sure that it can drain properly into the drain or condensate pump. Any restriction of this might cause a buildup of water in the pressure switch.
Thank you! We're glad you found the video helpful! As well dirty burners can interfere with the flame sensor, so you have problems again, make sure that the furnace is clean!
@@AmreSupply The flame sensor was cleaned yesterday morning, the furnace work fine all day but now it has the same problem today. The flames comes on for about 10 seconds and then shuts off and the cycle just keeps repeating. What else could be the problem?
@@chueyang7221 For the flame sensor to work it needs to be positioned in the flame and the burners need to be clean. There needs to be a path to ground from the burners to the furnace frame. If you have a multimeter you can test from the metal on the burner to the furnace frame to see if there is resistance or continuity. If there is no continuity then the flame sensor will not work as the circuit will not be completed. As well make sure that the flame sensor connections are secure and that there is no corrosion on the terminals to the control board.
Thanks that video talks around what my furnace is doing but not exactly. My gas valve receives 25.8 volts but only for two seconds. The igniter is hot as can be but I don't think two seconds is long enough for the gas to flow/ignite.
Thanks for watching. The voltage is good as it should be around 24v to open the gas valve solenoid. The solenoid will need to stay open, which will require a sustained 24 volts. It is unlikely for this to be a problem with the flame sensor as the control board monitors the flame sensor voltage usually over 7 seconds before shutting off the gas valve. This seems like an issue with the control board as that is what is dictating the incoming voltage to the gas valve. The control board is difficult to test, but is relatively easy to replace. You can see how to access it in the video linked below: th-cam.com/video/4SY8lRl8HV0/w-d-xo.html

I,ve never mind people watching me , but anyhow I call same man on thursday , he told me he comes monday which is today . I am reading & watching U & the others , so when the man come , he does not tell me nonsense . I thank U for your respond . GOD SPEED ❤
Its always good to ask questions to who ever is doing the work. Hopefully the service call helps narrow down the problem.
This is incredibly helpful. I don't understand why more of this information isn't readily available for those of us that are capable of doing simple repairs like this.
Thanks for watching we're glad you found it helpful! It takes a bit of time and knowledge to produce videos like these, and we have put a lot of effort into making very detailed troubleshooting series.

you just help me keep my kids warm in the middle of January in W.V. 20 degrees outside with 8 inches of snow 😊 Thank You !!!
Thank you for sharing we're just happy to help out especially on these cold winter days!
I’ve had a problem with my furnace for a while now and I thought I had tried everything. Was about to hire out a professional to come and check it out but decided to try and clean the flame sensor. I think that was the problem. 2 minute fix that probably saved me $100+. Thank you SO MUCH!!!
You're welcome, we're just happy to help!
If I were killed in war, I’d trust this man to step in and be my wife’s new husband.
AMRE has you covered
Damn! That’s a lot of confidence
Your video was very helpful in troubleshooting. The clear troubleshooting for each phase of operation made it easy to find the flame sensor was at fault.
Thankfully managed to fix it on a dangerously cold night of -27°C (-17°F)
My furnace would occasionally run normally. But every few hours, it would attempt to light 3 times, and shut off. I could hear the burners ignite for about 3 seconds, then they would shut off.
Investigated the flame sensor. It was clean, but was loose and not close enough to the flame. Tightened the screw and re-adjusted so was in the flame path, and now it's working perfectly. Although you didn't mention that particular issue in the video, it still helped me narrow it down.
Thanks for watching. We're glad that the video helped you get your furnace working again after such a cold night. You are right that this video didn't go into all the details on the flame sensor. The flame sensor is actually just a rod that sits in the flame. It doesn't sense heat, it completes a circuit from the control board, through the flame sensor, through the flame to the burner or heat exhanger, and returns through the ground wire. The position of the flame sensor, a dirty flame sensor or a carbon buildup on the burner can all prevent this low voltage DC circuit from being completed. Hope this helps provide a little more context!
My furnace was igniting then shutting off then on again continuous with no heat. The sensor had very little corrosion but I cleaned it and reinstalled and works fine again. I appreciate your time in making this video. Saved me $$$ Thanks.
You're welcome, we're just happy that the video helped you get it running again!
Vance, you're a good teacher; a calming influence and a motivational spark. With your help, I'll fix this! Thank you.
Thank you Carol for your kind words! It means a lot to know that our videos are helping to inspire people! We really have made an effort to try to help people gain more knowledge so that they can do the repair themselves or just have a better understanding for when they communicate with a professional.

Thanks Vance! Our furnace turned off on Christmas and you have saved us a lot of money and a cold Christmas day. Vance you're the man. XD
You're welcome Jen! We're so glad that the video helped you keep your home heated on Christmas day!
Excellent video! I found that after remodeling work, even with the system off, all of my sensors got dirty. This video narrowed it down to the main culprit, but gave me the confidence to explore my system further and check/clean every sensor carefully. Just took a tiny bit of dust to throw some of them off.
Thank you, we're just glad that the video helped you out! The flame sensor is particularly sensitive to a buildup of dust or carbon as it relies on a small DC current to travel from the control board, through ions in the flame through ground. This is how it proves that a flame is present. The flame sensor is nothing but a small metal rod. Nothing special about it.
This should be the first line of attack when you have a "Short Cycling Furnace Problem". I almost gave up after cleaning the furnace and checking the Nest thermostat, fan limiter, limit switches, replacing the air filter and fan capacitor, etc... I was ready to call the HVAC professional when I decided to give Google another try, I entered "Why does my furnace keep turning on and off", and I found this section (3:13) in your instruction exciting, (holy sugar!) cleaning the burners and flame sensor monitors are the solutions to my problem after all. It took me a day and a half to figure it out, I lost half of my hair scratching my head, thank you very much for your help, this post really made my day...
Thank you for sharing! We are just glad that people are finding these videos helpful and when it comes to the flame sensor, it is the root of many furnace issues for a good number of people. Cheers!
Great video. It just confirmed my last fix is the right one. I had already been through cleaning the flame sensor, took the burners out and cleaned them, and thoroughly cleaned everything inside that I could, replaced the limit switches and the furnace would still decide to not ignite on occasion. I took the pressure switch tubing off and some water in there. After draining that and blowing it out good it has fired up without a hitch.
Thank you for watching, we're glad that the video helped you confirm and narrow down the problem.
THANK YOU! It’s 16 degrees on a Friday night here and my heater pilot would not stay on. It didn’t match your video exactly because the pilot would continuously light and go off within a couple seconds but the fan was blowing the entire time. Regardless, I cleaned the flame sensor (which barely looked tarnished) and it immediately fixed the problem. I cannot thank you enough!!!!! ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
You're welcome, we're just happy to help!
It could be an issue with the thermocouple, so it might re-appear. th-cam.com/video/3EKbSiAJyiI/w-d-xo.html
Also if you have a multimeter you can test the thermocouple voltage to see if it is producing enough voltage to keep the pilot flame lit. If you have a spark ignition then your furnace might work slightly different than the thermocouple example as before. You can test the voltage similar to the steps in this video: th-cam.com/video/Mx6rZA9Yxv4/w-d-xo.html

You're welcome, we're glad that you found the video helpful!
By far one of the best DIY videos. I'm very handy and have been fixing my own appliances etc for years, including putting a new circuit board on my furnace a few years back. Is was having short cycle issues for the past 2 years and have done EVERYTHING mentioned in your video except for ONE thing! No other video or website that I've come across has talked about or mentioned the LIMIT SWITCH!! Thank you and wish me luck!!
Thank you, we're glad that you found the video helpful! We really try to make all of our tutorials informative especially with graphics and concise information. Best of luck with the repair!
UPDATE!! I first want to say that this is the ONLY DIY video that mentioned the LIMIT SWITCH as a possibility. Well I'm here to update everyone and can now report that the LIMIT SWITCH was EXACTLY my problem. I had the Short Cycle problem for a couple of years and had done EVERYTHING to correct it myself. Well I finally heard this info and purchased a NEW limit switch online for $24..PROBLEM SOLVED!! I want to thank AMRE Supply for these videos and will now subscribe to their channel! Thank You AMRE, you guys are lifesavers!!
I'm a first time home owner. This helps a lot thank you
Thanks J Lo, we're glad you found this video helpful!
Thank you for your helpful video. Had a dirty flame sensor. Removed and polished, and now everything is back to normal. Thank you!!
You're welcome! We're glad that the video helped you out!
I had a problem and my furnace kept switching off after few minutes of heating in repeated cycles and that was the last issue you walked through. I had to change the filter which is just a month old and it fixed the problem. Can't understand how a one month old filter can cause a trouble but the solution you provided was spot on. Your videos are phenomenal and well explained to the point. A big thank you!
Thanks for watching, we're glad that you found the video helpful. Was the MERV rating different on any of the filters? If a filter was a higher MERV rating and more restrictive than the others, then it can cause the heat exchanger to overheat.
My experience: buy the least restrictive filter
They are cheap 1.50 - 3.00 $ each and replace often especially if you got pets who shed inside the house .plus more efficient at moving the cool air in summer
Awesome video, great info, excellent graphics and clear communication - Top notch work!

Never worked on a furnace and had it up and running in an hour. Thank You!!!
You're welcome, we're just happy to help!
This is a great video very detailed but I’d like to add something to this. If the heater keeps shutting down and you have done all this! Check your condensate pump line. It might be frozen if it is up in the attic and it’s like 6 degrees outside. So if your condensation pump is hooked to your heater it will shut it down as well.
Thank you for watching. Yes that is an excellent tip!
Great video. It was my limit switch...just needed cleaned with emory cloth. Furnace fired right up and kept going. Thank you for your time.
You're welcome, we're glad that the video helped you out!
Well done and very educational. I hesitantly called a guy out who started immediately with the 'I hope it's not the heat exchanger,' for which I'd throw him out. He was pretty good at testing everything methodically, as an engineer though I was questioning things - enough for me to realize he didn't get it and just wanted to throw parts at it. These things are not rocket science so I'm sick of these technicians who come out with more stories than Shakespeare. I learned more from you in 5 minutes. I already suspected he flame sensor, but will review limit switch as well. The 'tech' wanted to replace the circuit board for $1800! I found them online for under $100 (btw, that is what I used to do so I don't need his warning of electrocution or 'every year the fire departments find people in attics' (he said that!). The other annoying thing is finding info in materials or on company's website - everything just refers you to other criminals, I mean 'techs.'
Thank you for sharing your experience and we're glad that you found the video helpful. This was one of our goals with the furnace series is to help homeowners gain a bit of knowledge. People go through the same stress with vehicle repairs, a little bit of knowledge can help prevent a mechanic from doing unnecessary work or over charging for a simple repair. Also $1800 is highway robbery for a control board. With the power disconnected these boards are very simple to replace.
@@AmreSupply Yep, you will do far better being transparent and honest than these hacks out there trying to get rich off every single call. Good branding! I've not swapped the board because I've been doubtful and prefer to review the other items like you showed. Business is so easy, but there are still these old school clowns hanging on to ideas that 'people don't know' (tell 'em it's danegerous.'), they'll be gone soon enough, I hope.
I called a guy which costed $180 came over, and only cleaned my furnace, then suggested me to replace the furnace, but didn't solve my issue.
I cleaned they flaming rod myself and now it worked for about 3 months.
but now, the furnace works only when the cover is opened, as soon as I put the cover on, it stops, even with the filter took off. Could you help suggest what's the issue? thanks
@@shw4083 They suck, as do plumbers, AC techs, water heater and appliance people, someone is teaching them bad habits - how about honest work for honest pay? Crooks.
@@shw4083did you ever figure this out? My error code is reading limit switch, if I have both doors on it will run for 5 minutes then shut off then cycle again a few more times before lockout. If I leave the flame door off it will just keep running without shutting off.
Thank you! It took 5 minutes to clean the flame censors and now my furnace is working properly again.
You're welcome Anthony, we're just glad to help!
This is the best video I've found thanks for the tips
You're welcome we're just happy to help!
You mentioned in the beginning of this video the different kinds of safety switches - pressure switch, flame sensor, flame rollout switch, and the limit switch and what they do. I was wondering what the flame rollout switch does and the signs of when to replace it? Your videos are awesome and I love this channel. Thanks for all the education!
Thank you, we're quite glad that you're finding the videos helpful!
The flame rollout switch monitors the burners, if there is an airflow issue and the flames are "rolling" out the front of the burner, then the switch will disconnect power.
If you notice a lot of carbon buildup around the front or and the switch then that indicates a flame rollout issue, and that will need to be investigated further.
If there are no signs of a flame rollout, but the switch is having issues, then it could be a faulty switch. The flame rollout switch should have continuity at room temperature. If it doesn't then it's faulty and should be replaced. This kind of failure is not that common though.
Wow thanks to your video, I was able to diagnose my furnace and resolve the problem!!! Gratitude!
You're welcome, we're just happy to have helped out!
tks very much, it was a dirty flame sensor, cleaned and is now working, will buy another as a backup - great video
You're welcome Rj, thanks for watching! While you're at it its a good idea to have an extra furnace ignitor on hand as a backup. Ignitors are a common point of failure as well.
at first I was sure the problem was going to be the igniter but after watching that video and allowing the furnace to try starting with the front panel off I could see that the igniter was working fine and I had flame for several seconds before it would shut off. I tried checking the flame sensor and wasnt too hopeful because it barely looked dirty. a quick clean with some fine sand paper, put it back in, turned the system on and it's running perfect! I also think the electrical connection may have been loose so made sure that was tight. thank you so much for this great helpful video! saved me at least $150 for a service call and who knows if they would have tried to sell me something I didnt actually need. I hope this business model is working for AMRE. I was totally ready to order parts from you guys if I needed them.
Thank you for sharing your experience, we're glad the video helped you out! You are right a loose connection, corrosion on a terminal, or a frayed or broken wire can cause the same issues as a dirty flame sensor.
Overall AMRE has come a long way in 50 years we're fortunate to be able to help people out with these videos! Thank you for the support and we'll still be around next time one of your appliances or fixtures needs a new part! Cheers
@@AmreSupply right on! you guys are the best!
Thanks AMRE and this video. My furnace keeps turning on, ignitor would ignite gas then off for three cycles. It's a Lennox G40UH. The diagnostic lights indicate bad ignitor. So replaced ignitor. Still the same. Then cracked open a beer and watched this video. Symptoms point to bad flame sensor in second part of video. So I cleaned the flame sensor as instructed. Lo and behold, it worked.

Another potential issue that could cause furnace turning itself off after running (with gas on) for a short time is that the outdoor exhaust and intake ports/pipes were installed incorrectly. If both pipes have openings (outside) next to each other, such as both facing down, then the intake may be sucking in the exhaust gas, causing a lack of fresh air/oxygen for combustion. Fixed easily by making one pipe face out and other facing down. Though illustrated clearly in instruction manuals, some installers don't do this right.
Hi Boris, thank you for watching. That is a great point and another good thing to look for when troubleshooting this!
Should the exhaust face down(with a elbow?) Or just no fittings at all- what about fresh air intake-a 45 elbow-or straight pipe also

Hi I have question my igniter turn on three times then my fire starts and my light is blinking 3 short and 4 long ones once the fire starts then stay lit everything else is normal the only problem is my igniter light up 3 * then I'll leave my gas releases them the fire and I change all three senses what do you think the problem is
Best to check what that code is. The code is different for each model so check your furnace manual or the diagram which might be on the back of the furnace door.
Also if the furnace ignites but doesn't stay lit or takes several times to stay lit, then it might be worth cleaning or replacing the flame sensor. That would be the first place to start.
Im getting three short and for long(34) bryant. Model # 310aav036070adja.
Ignitor Light Up 3 times and shut off with the machine on then only gas and fires up
@@gomasmas5727 The 34 code for that model is a "Ignition Proving Failure" what you are seeing is the furnace try to light 3 times then shut down and lockout until trying again.
The furnace igniter could be faulty or starting to fail, you can learn how to replace it here th-cam.com/video/LAAYMOpVf-8/w-d-xo.html
Also the burners could be dirty and obstructed, it best to clean them as part of regular maintenance th-cam.com/video/1giPLrObYb4/w-d-xo.html

This video is very helpful, thank you! I do find my furnace shuts off due to water in the pressure switch tube. But after clearing the water for a week, I got water in my tube again. This happens multiple times this year. Do you have any recommendation for this issue?
Thanks for watching. Check the condensate tube and make sure that it can drain properly into the drain or condensate pump. Any restriction of this might cause a buildup of water in the pressure switch.
Awesome video! According to the video my flame sensor needed a cleaning. Furnace is up and running fine now, hopefully this solves the problem
Thank you! We're glad you found the video helpful! As well dirty burners can interfere with the flame sensor, so you have problems again, make sure that the furnace is clean!
@@AmreSupply The flame sensor was cleaned yesterday morning, the furnace work fine all day but now it has the same problem today. The flames comes on for about 10 seconds and then shuts off and the cycle just keeps repeating. What else could be the problem?
@@chueyang7221 For the flame sensor to work it needs to be positioned in the flame and the burners need to be clean.
There needs to be a path to ground from the burners to the furnace frame. If you have a multimeter you can test from the metal on the burner to the furnace frame to see if there is resistance or continuity. If there is no continuity then the flame sensor will not work as the circuit will not be completed.
As well make sure that the flame sensor connections are secure and that there is no corrosion on the terminals to the control board.
Thanks that video talks around what my furnace is doing but not exactly. My gas valve receives 25.8 volts but only for two seconds. The igniter is hot as can be but I don't think two seconds is long enough for the gas to flow/ignite.
Thanks for watching. The voltage is good as it should be around 24v to open the gas valve solenoid. The solenoid will need to stay open, which will require a sustained 24 volts. It is unlikely for this to be a problem with the flame sensor as the control board monitors the flame sensor voltage usually over 7 seconds before shutting off the gas valve. This seems like an issue with the control board as that is what is dictating the incoming voltage to the gas valve. The control board is difficult to test, but is relatively easy to replace. You can see how to access it in the video linked below: th-cam.com/video/4SY8lRl8HV0/w-d-xo.html
@@AmreSupply Tnx,I timed it and it is definitely under three seconds.
My furnace works just fine I just like watching these videos
Thanks for watching! We're glad that you're enjoying the videos!
