- Explaining to home owners or do-it-yourselfer's about thermostat wiring. A step by process made easy to understand Air conditioning Thermostats. This is a show and tell video, I am showing what each white wire is a heat call yellow wire is the compressor, green wire is the indoor air handler fan, orange wire is the reversing valve, red wire is hot wire coming from transformer blue wire is common.
Comment with any questions!
Thanks for watching!

Thanks for this video you make it so easy to understand I’m a 62 year old woman , my thermostat just broke , quit on me and by watching your video i was able to get my cool air blowing by connecting the wires you specified is is 92 degree here , it will get me till tomorrow when i can go to home depot and get a new thermostat that i till have the guts to instal my self thanks to you !
Mr Jones you most definitely have saved more than a few lives helping people that are at risk of dying from heat stroke and heart failure ..im out of words and so very very greatful for you coming across this WAS NO ACCIDENT .. ..the lord works in mysterious ways indeed... God bless
you and all you do ..ima start crying
Thank you for taking the time to explain some of the basics of thermostats to help the DIYs out there. It would also help to explain that there are small relays in the thermostats that have contacts that can fail after so many repeated cycles of make - break and quite often the cause of the problems discussed that arise over time. Also explaining that the Letter Designations on the terminals correspond to the color of the wire used though that is not always a given in each and every installation. Cheers, Victor
Thank you …. I was able to reconnect the wiring on my thermostat for my heat with your helpful video without needing to pay for a service call!! It was not reconnected when moved during a remodel …. so thank you.
I watched a few other do-it-yourself thermostat replacement videos but I was left even more dumbfounded than when I first took on this project. Then I played yours and all my questions and concerns were thoroughly addressed. The fact that you took the time and explained not only what wire goes where, but what the function of each wire was, made the whole project crystal clear. And you were the only one to explain why RH and RC should be jumped. Now I'm off to kill the breakers and do the swap. Wish me luck! I'm going in!
OK. Project finished! I was a little concerned when the A/C didn't fire up right away, but maybe it just needed a minute or two to acclimate. Now it's working great! All I have left to do is to set the program. That should be simple enough. Thanks for all your help!
I am glad it helped
thx
Some of the relays have timers in them to protect the components.
On heat side they keep the fan running as the heat coils cool off.
On compressor side they keep it off so the freon liquid can disperse from the compressor so it doesn't lock up.
Never touched a thermostat, and I already feel like I can take on my new job. Seriously great video David Jones. You are making waves my friend.
This helped so much! Got a new thermostat and forgot to take a picture before removing wires and was so lost. you pointing out the jumper piece did the trick. thank you!
You're the man. This was very helpful to me to see the components to trace the wiring too! Thanks
Thank you. The Honeywell thermo manual said something different. This helped and got us heat. Thank you!
Thanks for sharing this - I was kind of struggling with some new thermostats and this info definitely did clear things up.
Thanks David! You helped my husband and I get our new thermostat working on a heat pump! You are awesome
I am glad it helped.. Thanks for watching
David Jones Mr Jones I have many years experience with auto electrical and took many classes . so in not 100% ignorant just 80% lol OK bought used rv to live in one night big rainstorm came through and filled 12v battery box with water and I experienced lights flickering etc . concluded transformer/battery charger fried out . .. I know I have to replace it but I am currently disabled and on very slim budget. . my question to you is my AC unit blower turns on but no cold air. I think the compressor is not turning on . is there a way to by pass thermostat just for a little while till I can afford new transformer / battery charger and new battery . I will replace them as soon as I am Abel to but the medication the doctors have me on raises my body temperature and I am quite uncomfortable with out AC . I know on a car you can easily do this but it not a car . any advice would help .. I have no voltage at the thermostat but AC blower motor works
David Jones.
David, thank you so much for a very detailed and informative video. I am a DIYer and a friend thinks their thermostat is bad. I am about to go and check it tomorrow and I would typically look for a wire that may have popped out or a bad thermostat cover that may have not engaged (snapped) back on to the base properly, as she removed it and changed the batteries. I hope she put the batteries in correctly !
Thanks again !! Well done.
Thanks for the video. There was a reference about the internal software that made me realize that the thermostat was default set up for conventional so I switched the setting to heat pump and the entire system worked perfectly. Thanks for saving me the $500 for a repairman.
Thank you sir. Your knowledge and compassion for taking care of your customers are commendable. I respect you and will call you . Thanks
Thank you so much for this video. My mom lives in Tennessee and she got a new thermostat and wired it wrong and didn't take a picture of how it was. This helps out a whole bunch.
Your common sense approach made the job simple. Thanks
I really appreciate this video and how to test the thermostat. My 81 year old Dad has an older Salem Travel Trailer and the thermostat had to be all the way up at 90% to be able to turn on. Today it quit put out heat all together. This video shows me how to test it...Thank you
you are so informative in your explanation>>>>
This is a nice video to guide you through and the real kicker is to talk to this very nice guy (David) to iron out any kinks. Thanks a lot for your help!
Excellent information provided in this video. Followed the steps and confirmed I had a bad thermostat, which I have now replaced. Everything running now as it should. Thanks for sharing your expertise!!
thank you for doing what no one else has done and explain what each wire does. makes it much easier to understand what your doing. in my case c is common i hooked it up to +24 volts instead of common. thank you...
Perfect! Thank you for your video, this was exactly what I needed. I was able to replace my thermostat w/o a problem.
Good overview - New thermostat is up and running. Thank you.
I never write comments but a great video really easy to understand and you helped me a LOT! Thanks for taking the time!
I appreciate your simplifying. You really make it understandable & easy. Thanks I'm Dave Overbey on TH-cam fight & defend.
thanks for watching
The world needs more people like you! I’m gonna give it a shot. Thank you.
Thanks. Watched a dozen videos that didn't help before finding this one. Turned out my thermostat was bad--only way I realized it was by twisting the control wires together as you suggested. I had thought it would be something else because the thermostat is only ~2 years old. Not thrilled with Honeywell, but very grateful to you for posting this video.
Best video I've ever watched it's straight to the point easy to understand he accomplished everything he was trying to and no more no less perfect
Thank,you I'm hooking up a lux the first one I've ever done and I appreciate you explaining what the wires mean..I hope I can do this alone
Thanks so much for making this clear. I was so confused between heat strip heating vs. emergency heating which i understand uses the same heat strip.
This is a great and useful video. No fluff, just the straight dope. Thanks.
I wish I lived closer to you, you would have another customer. Thank you sir explained really good.
Super helpful video. A while back I used it to learn the basic colors and directions for a 1991 mobile home electric heat pump and I was able to complete the thermostat installation. I was hoping to translate a 1953 gas furnace, but inside was TH1 and TH2 AND TR'S and jumper wires and it's a mess, so I think it's time for a professional. Lol
Thanks for doing your concise easy to understand videos on HVAC, I have learned a great deal from your efforts.
Thanks so much Mr. Jones. Great explanation...
You are a nice guy. Your "bypass" method of testing for bad thermostat is simple and useful. You share a lot of good info with good explanation. Good on ya.
You are awesome. After watching this I am not scared to tackle changing my existing Honeywell T8602D2018 thermostat to Honeywell TH9320WF5003 Wi-Fi
Just pay attention
You can do it
thanks For watching
Great video. Thanks. Very helpful.
Thanks for your help! You explained the definition of the wiring that got me up and running. Yup bad thermostat. Thanks again 👍🏼👍🏼
Best video ever , thank you, you just helped me to hook a thermostat to a window AC , most window ACs are not accurate with the room temperature , after that video which is what I need exactly to know what is those codes refers to, I know now where the power should go in and where to go out based on the temperature you set on the thermostat. Thanks again
Exactly what I needed, thank you!
Thank You so much for showing & teaching me how to replace my Thermostat, this was the best video I saw and I looked at a few and they did not go over what wire went where & what they do…
Mister I could give you a big hug. if I hadn't tried ur app I would be cold.my inlaw put me in a thermostat last winter but it never worked.tonight I had my grands over trying to keep house warm with stove but it was still chilly.I tuned to your app hoping to see what I could do to the thermostat put in last winter.i notice a small cardboard between the circuit connection barely visible that said quite remove. I just slid it out an that was the problem.this was something to me an thanks to your video I would still be cold. thanks for helping those that need help like me.
Thank you for the info it worked perfectly!
Thank you for posting this, it helped me install my new Honeywell digital programmable thermostat in a house that was built in 1953 -- and had two separate thermostats... one for the original oil heat system, and one for the retrofitted air conditioning that was installed in the 80s.. works like a charm!
Thank you so much this helped me a lot 👍🏾👍🏾👍🏾
I am very much convinced of this video, and the kind of explanation that you have to say is also very good, and by showing one thing, you give the message about it.
Thanks David. One thing that had me puzzled was that I had Blue wire in the bundle, but the terminals on the Thermostat had no "B", rather there was a terminal marked "C"... I didn't know what C stood for until you explained it, or where I should put the Blue wire. Thanks again!
Thanks! I just replaced my old round Honeywell with a new programable thermostat. On my old Thermostat the Blue wire was placed on the Y terminal. When I wired up the new one I put the Blue on the B terminal. No wonder my AC compressor didn't come on. I didn't have a Yellow wire and had no idea that I was leaving the AC compressor with no control wire. Your video showed me just what I needed and taught me a lot. Now the blue wire is back on the new Y terminal and everything is working fine. I don't need a common wire? Thanks again.
+Ron Green I had the same setup myself yesterday. I noticed the blue wire went to the Y terminal on my old thermostat. I just wired the new thermostat the same way the old one was since it worked fine before. I hope David answers our question about the common wire.
Trying to change mine and notice my BLUE wire is connected to YELLOW terminal??? Do I wire the new thermostat the same, or, put blue to blue?
nice job been looking for someone to explain this in layman terms
THANK YOU!! You solved our AC Wiring Problem. Many thanks from Canada
This man is "the man".
my apartment ac would blow heat then ac and was not sure wtf was going on. I watched your vid and opened up the thermostat and the Orange wire and Yellow wire was reverse connected. After I plugged them in the correct connection AC unit is working now. Thanx for the video from 7 years ago. =)
I glad it helped to spread the love. Stay warm.
Great Video. Was able to diagnose and fix my problem of heat not blowing with heat pump. The orange wire not in the right spot.
Getting ready to install a Honeywell and this looks simple enough to do. Thanks.
Thank you. Very informative.
Very cool that you made this video! Great job!
Absolutely the best video explaining the wiring of a heat pump system with the thermostat. Excellent.
thank you
Thanks for the information. very informative.
Thanks for the 4 minute refresher on the wiring I've done it before but 15 years don't go along too well don't get along too well with my memory, thank you very much you are very informative ☆☆☆☆☆
Mr. Jones , You are Saint! Thanks for all you do.
He sure is ❤😊
Thank you so much!!!you just saved a phonecall and money. So great ful to people like you who like helping. Keep up the great work Sir.
Mr. Jones, you are the man. This is going to help me install my ecobee4.
Much appreciated. You are a nice person for sharing your knowledge and experience.
Many thanks.
Nicely explained. For people like me, a diagram is very helpful. Thank you
Thanks, I appreciate that.
Thank you for this video, this was very helpful.
thank you, this is very helpful.
Thanks, good information explained so even a dummy like myself can understand. You have a gift for this kind of thing. Keep up the good work.
Thank you so much, this just saved my night!
You have just saved me from freezing here in michigan! Thank You, Thank You, Thank You!
Hey Jenny, Bud here. Got a minute? If so, please call when you can? Thanx.
Thanks so much, I finally got the heat on
Excellent video. Thank you for sharing your skills.
I appreciate the video information and your desire to help those of us who don't know wiring and functioning of the thermostat.
I'm trying to figure out which wire will allow me run y thermostat without batteries.
Thanks for sharing your experience!
As luck would have it, this is the exact same thermostat I just used to replace the old mechanical one. I picked it up for a buck at a thrift shop, works fine!
Wonderful video. Thanks for showing the demo parts.
Thanks for sharing this video David. I am new to HVAC this is a very helpful!!!
thank you, thank you, for a novice this really helped me to understand the what was doing what in trying to see if the problem was the unit or not... again this was done very well.
Last Fall my AC compressor was coming on when the heat would turn on. I had turned the circuit breaker off for the AC so I could troubleshoot it in the spring.
Now that it is spring, with the AC power turned back on, the AC will not turn on. Both the blower fan motor and the compressor are not coming on in AC mode. The heat is working normally. I do also have the thermostat set in the HOLD mode so I could rule out a program error/issue with the thermostat. Any ideas. Thanks and very detailed video. I gave you a sub too.
Mr Jones, thank you for the educational videos, Im in NJ, Im wondering if I could wire my stream oil furnace and central AC unit to a single thermostat. i currently have a Honeywell T87F controlling the furnice, and a Honeywell T8112C controlling the AC unit. thank you
Thanks for this, between your video and another website reference.. I was able to gain the understanding of the system at the thermostat wiring level well enough to navigate my issue. I attempted to get my local HVAC technician to handle this matter initially, but his quote and subsequent rate was laughably ridiculous to me. I specified that my issue was: 1-2 wires being moved into a different terminal, a process that takes less than 2 minutes to resolve (excluding travel time) with a basic knowledge of those standards and a small flat-head screw driver. I look to empower local businesses and professional trades, but its ridiculous quotes and rates like that that turns home owners into do-it-yourselfers. It's pretty gratifying to solve my issue and 'save' $90 in 2 minutes of effort beyond the time it took to watch this video and read a couple paragraphs on a resource site, but I can't help but feel disappointed that I can't just delegate the matter to an individual who embodies and/or represents the industry without these obnoxious value of time and service, cost consideration. I mean, I feel at odds about the whole state of affair in these interactions.
This was an incredibly informative video. This stuff was just beyond my grap and you put right in reach. Made it much more simple. Thanks.
Thank you David! very helpful
Great video with easy to understand wording and excellent visuals!
thanks for posting this video! we were freezing! this video showed me my thermostat was bad and saved me a a bunch of money and my wife loves me again!
Great job. Now, please, explain Calculus. I know I'd finally get it.
I'm waiting if he will make a chemistry video.
Really helpful! It was nice to double check and make sure I had it wired correctly
thanks for watching
Thank you my thermostat is bad, you saved me some money, thank you very much
Great video well detailed!!!!! Thank u sir.
Mark Smith
I Absolutely Lovvvvveeeee! The Way You Teach... Wish I Could See The Thermostat a Little Better...
THANK YOU, FOR YOUR COMMETT
Excellent video ,,,very clear
thanks
Thanks for the info, very helpful. I need to install the new generation thermostats that works with ATT. this is up here in NY, if the c wire is not present, can I draw the 24 volts from the rh by pulling a jumper to the c so the thermostat gets powered?
Also is there another way to test the thermostat? I have tried 2 of them and neither went on for some reason although I had 24 volts at both the rh and the c
Did you do the program, it come factory set for gas not electric.
Have to reprogram settings.
Thanks for sharing your knowledge .
You did a nice job with this!
Thanks James
Wow, clean explanation. Thanks!!!!
I'm swopping out my old 2 wire round thermostat for a Honeywell focusPro TH6110D, the furnace is a Lennox Conservator G11E with 24volt transformer, that has heat only- nothing else, so if I get it right from your video I'll be connecting one wire to the RC/RH jumped terminals, and the other wire to the C common terminal.
My 2 wires don't have colors at all because when I brought the used but perfectly working furnace home years ago from work which replaced it with a 92% unit, I had to install everything myself including all the duct work, returns and the wiring to the thermostat, which since it was only 2 wires I used a roll of heavy speaker wire I had, but that was like 18 years ago so I have to go back and revisit it all now.
