Brother you just saved me a $200 service call, and gave me an excuse to get one of those nice app based thermostats. Plus it's my birthday today. It started off bad, but seeing that I saved at least $200, and learned a bit about my furnace, that's the best gift I've gotten all day.
I don't know ANYTHING about hvac..but recently had a recharge since i have a slight leak. I'm sure many have told you already but I just have to say, THANK YOU so much for all your videos. I've watched them to learn and understand what's going on so I can educate myself. You are doing the community such a service. You are concise, clear and don't spend your time wasted on technical jargon. IMO, that demonstrates how well you know and and understand what you do. Please don't ever stop sharing whatever you do, you are so absolutely appreciated by the community!
Wow! I can't believe what I've learned in less than one hour here. Thanks. I am an electrical and computer engineer, but until today, my central air system was just a big "black box" to me! Glad to have that cleared up.
OMG THANK YOU!! I tested the board numerous times, everything had power but the inducer didn't have power. Finally I found your video and jumped it using a paperclip and BOOM the furnace turned on and was making heat. Ordering a new thermostat now, thank you so much!
Jay, after replacing the control board didn't solve the no heat problem and numerous other checks using your vids, I verifieded with a paper clip at the furnace and then the thermostat that it is the thermostat that I replaced a few months ago either was bad then or more likely I didn't throw the breaker and ruined it. I have just ordered another Tstat. Thanks for all your help. You saved me again and never have had to spend the money on a teh visit
Man, you saved me! My thermostat was bad. Weird because I bought a honeywell cheapo several months ago. What happened is I turned on ac for the first time and heat seemed to come on and so did the compressor at the condenser. I turn off the thermostat and seemed like 7 to 8 minuets before it finally turned off. Anyway, I jumped red and yellow and boom , my ac is throwing cold air. I will be at home depot in the morning. Thanks man for this video and all your videos. I learned alot tonight.
So glad I found this video. I thought my contactor or short cycle relay was bad. After watching this and jumping the terminals I determined I had a bad t-stat. New batteries didn't fix it. New one installed today and everything works! Thanks for posting this.
Watched Several of his videos ... They are exceptionally informative in layman terms. His simple details on the videos leave little to question... My hats off to him! and thanks for saving me a wait and a service call.
I am very appreciative....you deserve to be recognized for the help you offer....believe me without your video I would literally bake in my apartment....I live in Arizona and someone I live with took the cover from the thermostat so I would have to suffer the heat.....Yes crazy right? But that person only wants to see me suffer...and be hurt....or have to struggle....anyway enough about that! Your awesome and I just want you to know that I am so grateful and could never thank you enough! You are needed for your knowledge in this matter. Thank you! Thank you! Thank you!
Great job! You are a very good teacher. Explained the essential elements of the problem/solution in a easy to understand and concise manner. Thank you!
One very important thing he forgot to mention is NOT TO JUMP "R" to "C" or be VERY careful not to touch the "R" to "C" as this will burn the fuse on the control board or trip the low voltage fuse inside the furnace. In most cases you will not even know you did this as it will not spark or anything. The fuse is like a car fuse that sits in a slot on the control board or sometimes a button on the housing where the control board sits.
R is usually the hot wire with 24 volts and C is the neutral wire, so if they touch it is like putting a wire from one hole in an outlet to another in the same outlet !! but because the voltage is 24 and not 110 or 220, it usually will not spark and not electrocute someone.
Yeah I just accidentally jumped R to C (red to blue in my case). Thanks for revealing the fuse in my furnace. Found it. Going to the auto shop tomorrow for a replacement 3A blade fuse.
Thanks, Jay. Great video. It helped me to determine my thermostat is bad. I had a power outage this morning. When power was restored my ac fan came on blowing harder than usual. I turned the thermostat to off and the fan continued to run. Only after shutting off the circuit breaker did the fan stop. So I did your test using a coated paperclip and snipping off the coating at each end of the paperclip. I jumped from R to Y and turned breaker back on. Outside unit came on to cool. I have been a subscriber for months! Thank you for helping so many people such as myself.
Great video. Thanks much! As a suggestion, I would first start with red and green wire (fan) with the jumper since there is no timer or limit switch on that circuit. By using the red and yellow (A/C) you might turn on the timer/limit switch because the A/C compressor has a high and low side for pressure and possibly damage the A/C unit. If you activate the A/C timer/limit switch, the A/C unit may not operate until the time/limit switch times out.
Just wanted to say thank you. Ac went out on my 8 year old house. Replaced capacitor and contactor because they are the least expensive parts but unit wouldn’t kick on. Turns out had a bad ecobee thermostat I bought after building new home.
Thank you again !!! You explained everything very simply on how to trouble shoot the thermostat , to eliminate the thermostat from the AC or the heating. I did this at my niece's house and found the problem was the thermostat . Thanks again !!!
Thank you for this great video (and series) Jay. My A/C wasn't starting up, so after some investigation I determined that the major components in the AC unit appeared to be fine but the contactor switch wasn't engaging. I viewed your video on the top ten reasons for that not working and landed here. I jumpered my thermostat and sure enough the contactor engaged and the unit started cooling so I knew with confidence that the thermostat was faulty. As a bonus I found an unused fifth wire running to my thermostat that I was able to connect to common on the furnace control board so that I could get a WiFi enabled replacement that didn't require batteries (it might even be the same Honeywell unit you have pictured in the video). I should also mentioned that the unit I replaced seemed otherwise fine - the display looked okay and the furnace fan was still blowing (I did replace the batteries as a cheap test anyway but it didn't help). So it would appear that a single system is capable of failure on a thermostat without the others necessarily being bad too. Thanks again - I loved being able to figure this out by myself without making a service call (or buying replacement parts at random to see if that might be the solution).
Glad to hear you were able to track down the problem and get it fixed! People like you are the best :) Many people would only watch one video for a couple minutes and then comment right away asking, "My AC doesn't turn on, what do I do?" You actually took the time to watch the needed videos and figure it out. Congrats on repairing it yourself! Next time around it will be easier ;) Thank you for commenting and sharing your experience!
Thanks for saving me from freezing, you are simply great. Everything you said worked as in your video, my heater is now running and the house is getting warm. If I understood right putting jumper wire between R and Rc will make both cool and heat work. Before I had the wire in Rc only and AC worked fine but heat didn't.
RC and RH are separated to accommodate systems that have two transformers. If you only have one transformer, you terminate to either one and have them jumped together. Most stats will have a factory jumper already installed as most systems have only one transformer.
Thank you for your Videos. They have helped me out a lot. And no the video was straight forward, and not confusing at all. We DIY People appreciate your work.
You Sir are a blessing Thanks so much for sharing. A friend had her condenser fan making noise so we ordered a new one but shot some lube into the shaft and now it is quiet 2 days now. that was a diff vid of yours
What if you are going from an older 4 wire thermostat to a newer thermostat that specifies a green, fan wire? The new thermostat is the Honeywell 6580 that you showed on video. The HVAC is a Rheem
There certainly are things that are much easier to understand, than they are to explain! You did a very fine job. (I even got it the first time, before the well summarized recap. Thank you for taking the tine to share!
Thanks for your explanation. I found this jumper wire by my air handler after an HVAC inspection. I thought something might had come loose, now I know they were probably using it to test it.
FYI, It just started getting warm and my A/C stopped cooling/working , the Cool temp was set to 83 and the current temp in house was 85. The fan in the house was working but I went outside to see if the compressor/fan were going but it was NOT. So, it was NOT being turned on by the thermostat ( or the fan/compressor/capacitors were bad ). So, I changed the batteries ( 2 AAs ) and then tried to turn on the Thermostat but it stayed in the OFF position no matter what the COOL or HEAT setting was. So I went to chatGPT AI and it said to press the RESET button on the thermostat ( using a small screwdriver to push into the reset hole ). Voila , the Thermostat re-booted and I was able to set the Cool temperature and startup the A/C. So, with a good DIY attitude and Jay you can fix things too !
Thank you so much! After watching three of your videos and following the trouble shooting suggestions I found: 1) we had an abandoned mouse nest in the outside A/C unit 2) our thermostat is faulty. I’m off to get a replacement now! Thank you again for saving me a ton of money and not having to make a service call!
So, replacing the thermostat made the outside unit start working again, but the air blowing through the vents still isn’t cold. :( Guess it’s time to call a repair guy?
@@kyla1828 My guess would be that the compressor outside is not coming on. Only the fan is running which makes it look like it's working normally. Perhaps a chewed wire or a bad capacitor? It is up to you though.. I have plenty of videos on the topic that you can use to track down the problem or it's time to call out a tech
My Symptom: Air Conditioning working fine with no Issues. But when I would turn on the heat I would get a wiring error on the Nest E103 W1. Note: the Compressor would short cycle in heat mode but not in cooling mode. After about 10 minutes of this I would get the crossed wrenches symbol on the Nest. This system has been working for 4 plus year prior to the error message. Love your AC videos! FYI I have a 5 Ton Trane handler and a Trane Model 4TWX8060A 1000CA Compressor. When I jumped the R1 and W1 to by-pass the Thermostat it blew the 5 amp fuse in the air handler. Not sure what I did wrong? However, once I got the fuse replaced I abandoned the thermostat by-pass test and re-did the R1, Blue Common, and W1 connections at the compressor and now all seems to be working. Thank you for all the helpful videos!!!
Thanks Pal. I have an 𝗢𝗟𝗗 Perfection furnace. Built like a tank, very simple. No heat so first I changed out the thermocouple, nope. Then checked out the transformer which was within spec. Next was the Baso switch, nada....I'm running out of stuff 𝙄 can do before I have to call a repairman. Didn't think the thermostat would be bad. But as a last ditch effort I checked it out per your video. 𝙎𝙪𝙘𝙘𝙚𝙨𝙨 !! the burners came on. Now to return the Baso switch and get a new thermostat.....𝙏𝙃𝘼𝙉𝙆𝙎!! Oh yes, 𝙇𝙞𝙠𝙚𝙙 𝙖𝙣𝙙 𝙎𝙪𝙗𝙨𝙘𝙧𝙞𝙗𝙚𝙙
U deserve more than words of million thanks... If I wanted to install a new ther... how difficult is it ? I never had to replace one b4 I got 4 wires, Red Green White n Yellow
I wish I could’ve seen this video before .. I remember I didn’t know what to do and i call an ac service.. but im glad i did subscribe to see all videos and learn more from a professional..
Hi again Madara! :) Thanks for subscribing and watching my videos! Hopefully from now on you will be able to fix all the problems yourself! With all the self-learning you are doing, I am sure you will figure out any future problems.
You are the best on how you explain the process of troubleshooting. I have question for you. One Smart termostat Nest was set to Heating. But the system turned on the AC during winter and caused the evaporator to freeze. For troubleahooting:- 1. Y1 is removed from the circuit board at furnace, and removed the Nest thermostat face. Y1 still connected on terminal plate of thermostate. And It read 24v on Y1 at furnace side while termostate is not even covered. If Y1 is removed from termostate terminal, it has no voltage down the Furnace side Y1. I believed the Y1 is getting power at terminal plate of thermostat. Which means RC was creating direct connection to Y1. What do you think?
Another excellent video but sadly nothing happened on jump. Have been going step by step at least I can rule out the thermostat. No fuse in sight, connector works when pushing in, have a Payne and no obvious or accessible float valve when I tried to check. The mystery continues thanks for sharing your expertise
Jay, help! Today I noticed that he AC unit wouldn’t come on at all, so here are the steps I did: First, I took readings with my multimeter at the thermostat. 24 volts Then I checked outside at the contactor and I had 24 volts going in. Came back to the thermostat and thought it could be a broken thermostat. So I created a little jumper cable like you said (running red to yellow), and bingo! The AC unit came on. So this indicated that I may have a bad thermostat...then, I messed up. Even though the compressor and the fan came on, I still didn’t notice any air blowing out of the vents in the living space. So I thought, oh, I must have to connect the red to the green one (fan) and the yellow (AC) together. Then I thought, “well, I might as well connect blue, yellow, green, and red together.” So I twisted all of them together (but first I shut off the disconnect). Then I flipped the disconnect on and now I have nothing. And when I went back to separating them and putting them back into their designated spot in the thermostat now I got nothing. No voltage, and the thermostat is completely dead now. Now I don’t know where to go...perhaps I blew a fuse or something? Any words of wisdom?
Hey Nick! Sorry to hear about your troubles! It sounds like either your thermostat may be bad or perhaps weak batteries? It would have been okay if you wired G, R, and Y together.. But G is for fan, R is a hot wire (24v) and C is a common. By connecting R and C, a direct short is created. Most likely your 3 amp fuse is blown. It should be in the furnace control board. After you replace the fuse or reset the little 3 amp breaker, I would watch this video next as to why the blower is not coming on: ruclips.net/video/JSgLGTAbDF8/видео.html
You sir are a wealth of knowledge! I'm subbed! I am having these issues at present and came across your channel and have been watching the videos you posted. My furnace just started short cycling recently and I am trying to troubleshoot it with out calling for repair but that option isn't off the table. I have a lennox elite g50uh. I don't have the on/off switch at the furnace so I have to trip the breaker. I cleaned the flame sensor though it really didn't look that dirty as compared to what the videos have shown it can look like but problem remains. I will replace it since it doesn't cost much and see if that fixes it. Blower fan starts, the igniter lights,, I get flame but it turns itself off. It either turns itself off quickly or turns on but stops shortly thereafter. I've wanted to replace the thermostat to something a bit more modern (and I'm not sure if this is the problem).
Thanks for putting your info out there, helped me get my furnace going again, for zero dollars out of my pocket. Trouble shooting is the hard part. Swapping parts is easy.
Exactly what I was looking for; thanks, esp. for the excellent camera work. As a bonus, I get to buy a new toy: magnetic jumper; never knew that was a thing.
You should look up heat pump thermostat wiring since it seems like that's what you have. Here's a short summary: RC is power to cooling, RH is power to heating. These two are often jumpered together (internally or with a jumper), as if you only have one R terminal. O or B is for the reversing valve O or B is the common. Just look what color wire goes to C in the furnace to confirm. Y is cooling W is heat G is fan
You're right the RC/RH are jumpered together. I followed your advice and when I connected the R and the Y, the AC started running so I have a problem with my thermostat
Hello and thanks for the help! I need to bypass the 2 speed fan control with capillary on my ancient central air unit until the new switch arrives. Blue,black and red wires. Thank you

Thanks for sharing the info. The water leaked from the roof on my wall and the thermostat got wet. I thought the unit would start working after drying, but it didn't even after completely drying the unit. I changed the battery as well but it didn't turn on. Does that mean the thermostat has gone bad? The unit is "Honeywell VisionPRO 8000 Programmable Thermostat". Your comment is much appreciated.
Well done and thank you for that awesome tip. My unit is not working and your advice, gives me more time to consider options. Great safety comments too, really appreciate you!! I do have a question, my issue with my AC is I accidentally disconnected the wires from the outdoor unit to the sensor. And the wiring the installer did was to connect to the same outdoor safety switch that brings the line to the load. I can't find any advice on how to reconnect the sensor wires.
Thank you for your vids - super helpful and appreciated. I have a problem with no power to my thermostat but power at the board. Happened last night during a rain storm - probably unrelated but not sure why it would just stop working like that. The breaker is fine and the board is getting power. Thermostat connection reading 27 volts at the board. I also checked if the the water pump was working or if the float tripped anything but it appears fine. Any suggestions on what else I should look into? Regardless, thank you for these vids. Really helps to understand 👍
I would like to say thank you. Your video was easy to understand and very informative. After following the steps you described i was able to determine that i had a faulty thermostat. Once again thank you.
Awesome video. It worked. Just one question and it's probably a stupid one. That's all I need to do until they can come fix the thermostat right? It's running now and will continue to run until I flip the switch. Is that a safe way to run it?
Thank you for the great video. I have a question with regard to the bypass. You mentioned that it is better to turn the furnace switch off After you find out if the thermostat is getting power to do the bypass. How can the motherboard gets power to turn on things if you switch the furnace off, am I missing something?
Thank you Dude!! Just replace my thermostat and the technician did not do a by pass from R to RC and my AC turned on. The oil provider ROB here in NY is charging mr for 125 dollars diagnostics and 215 per hour of labor and plus for parts and blah blah blah!! I just did it my self bypassing..
love the video. There is no power to my thermostat after checking with a meter and all breakers are good. There is power to the outside condenser. Any ideas of what to check next? This is a split system heat pump.
Great Videos! Very thorough and clear. I decided that some of those magnetic jumpers would have come in handy a few times so I ordered some. I was glad i thought to see if you had a link for them, which you did, so I cleared my cart and used your link instead. You deserve the support even if it is only a little.
Thank you so much for your explanation! You saved me a service call at the very least and possibly being upsold into a new system. My confidence level has risen!
If you have gas heat, you only jumper red to white as the white call will energize heat and the fan without green being jumped. Because gas heat fires the gas first while delaying the fan, the fan will be brought on by time delay. if you have a heat pump, wire red,green,yellow,orange....those four together will call for the indoor fan, the compressor and the reversing valve.
So if a thermostat isnt energizing G on the thermostat side. Can I bypass it by wiring G to C? Or do I have to jumper G to energize with cooling/heating respectively based on season?
Rob, thank you for adding your two cents. It was appreciated and I don’t have any emotional connection to whether you care about me or not… (like Others.)
My AC turns on and cools the house, but DOESN'T turn back on to cool the house again when it heats up again. Any idea what that can be from? Thank you for taking your time to read this and your videos are great!
Sounds like something is wrong with the thermostat. If it has batteries I would try replacing them first. If problem persists, then likely the thermostat is defective. Only way to check for sure would be to check voltages in the furnace with a meter.
@@WordofAdviceTV Thank you for the reply first off! I'm gonna swap out the batteries tonight and most likely purchase a new smart thermostat in the very near future.
thnak you so much for all your clear videos,you are actually helping lots of poor people,god bless you always my friend,cheersssss.......

So, I changed the batteries ( 2 AAs ) and then tried to turn on the Thermostat but it stayed in the OFF position no matter what the COOL or HEAT setting was. So I went to chatGPT AI and it said to press the RESET button on the thermostat ( using a small screwdriver to push into the reset hole ). Voila , the Thermostat re-booted and I was able to set the Cool temperature and startup the A/C. So, with a good DIY attitude and Jay you can fix things too !
Thank you so much! After watching three of your videos and following the trouble shooting suggestions I found: 1) we had an abandoned mouse nest in the outside A/C unit
2) our thermostat is faulty. I’m off to get a replacement now!
Thank you again for saving me a ton of money and not having to make a service call!
Glad to hear my videos helped! Thank you for watching and commenting!
So, replacing the thermostat made the outside unit start working again, but the air blowing through the vents still isn’t cold. :( Guess it’s time to call a repair guy?
@@kyla1828 My guess would be that the compressor outside is not coming on. Only the fan is running which makes it look like it's working normally. Perhaps a chewed wire or a bad capacitor? It is up to you though.. I have plenty of videos on the topic that you can use to track down the problem or it's time to call out a tech
My Symptom: Air Conditioning working fine with no Issues. But when I would turn on the heat I would get a wiring error on the Nest E103 W1. Note: the Compressor would short cycle in heat mode but not in cooling mode. After about 10 minutes of this I would get the crossed wrenches symbol on the Nest. This system has been working for 4 plus year prior to the error message.
Love your AC videos! FYI I have a 5 Ton Trane handler and a Trane Model 4TWX8060A 1000CA Compressor. When I jumped the R1 and W1 to by-pass the Thermostat it blew the 5 amp fuse in the air handler. Not sure what I did wrong? However, once I got the fuse replaced I abandoned the thermostat by-pass test and re-did the R1, Blue Common, and W1 connections at the compressor and now all seems to be working.
Thank you for all the helpful videos!!!
Thanks you so much! Your video are very very helpful!
perfect explanation, thank you Sir!
2:26 is the single most considerate thing i have ever seen in my life. faith in humanity restored.
Thanks Pal. I have an 𝗢𝗟𝗗 Perfection furnace. Built like a tank, very simple. No heat so first I changed out the thermocouple, nope. Then checked out the transformer which was within spec. Next was the Baso switch, nada....I'm running out of stuff 𝙄 can do before I have to call a repairman. Didn't think the thermostat would be bad. But as a last ditch effort I checked it out per your video. 𝙎𝙪𝙘𝙘𝙚𝙨𝙨 !! the burners came on. Now to return the Baso switch and get a new thermostat.....𝙏𝙃𝘼𝙉𝙆𝙎!! Oh yes, 𝙇𝙞𝙠𝙚𝙙 𝙖𝙣𝙙 𝙎𝙪𝙗𝙨𝙘𝙧𝙞𝙗𝙚𝙙
Word of Advice Thank you! Thank you! Thank you! I'm a 69 year old women and I just fixed my air conditioner!
U deserve more than words of million thanks... If I wanted to install a new ther... how difficult is it ? I never had to replace one b4 I got 4 wires, Red Green White n Yellow
I wish I could’ve seen this video before .. I remember I didn’t know what to do and i call an ac service.. but im glad i did subscribe to see all videos and learn more from a professional..
Hi again Madara! :) Thanks for subscribing and watching my videos! Hopefully from now on you will be able to fix all the problems yourself! With all the self-learning you are doing, I am sure you will figure out any future problems.
very good! stay short in explanation and right to the point! as shorter the videos, the better it helps!
You are the best on how you explain the process of troubleshooting. I have question for you.
One Smart termostat Nest was set to Heating. But the system turned on the AC during winter and caused the evaporator to freeze.
For troubleahooting:-
1. Y1 is removed from the circuit board at furnace, and removed the Nest thermostat face. Y1 still connected on terminal plate of thermostate. And It read 24v on Y1 at furnace side while termostate is not even covered. If Y1 is removed from termostate terminal, it has no voltage down the Furnace side Y1.
I believed the Y1 is getting power at terminal plate of thermostat. Which means RC was creating direct connection to Y1.
What do you think?
Another excellent video but sadly nothing happened on jump. Have been going step by step at least I can rule out the thermostat. No fuse in sight, connector works when pushing in, have a Payne and no obvious or accessible float valve when I tried to check. The mystery continues thanks for sharing your expertise
These hvac videos are amazing my dude!
Very helpful, thank you!
Thanks to your video I have heat on a chilly night.
Happy to hear that! :) Thank you for leaving a comment, stay warm!
Jay, help! Today I noticed that he AC unit wouldn’t come on at all, so here are the steps I did:
First, I took readings with my multimeter at the thermostat. 24 volts
Then I checked outside at the contactor and I had 24 volts going in.
Came back to the thermostat and thought it could be a broken thermostat. So I created a little jumper cable like you said (running red to yellow), and bingo! The AC unit came on. So this indicated that I may have a bad thermostat...then, I messed up. Even though the compressor and the fan came on, I still didn’t notice any air blowing out of the vents in the living space. So I thought, oh, I must have to connect the red to the green one (fan) and the yellow (AC) together. Then I thought, “well, I might as well connect blue, yellow, green, and red together.” So I twisted all of them together (but first I shut off the disconnect). Then I flipped the disconnect on and now I have nothing. And when I went back to separating them and putting them back into their designated spot in the thermostat now I got nothing. No voltage, and the thermostat is completely dead now. Now I don’t know where to go...perhaps I blew a fuse or something? Any words of wisdom?
Hey Nick! Sorry to hear about your troubles! It sounds like either your thermostat may be bad or perhaps weak batteries? It would have been okay if you wired G, R, and Y together.. But G is for fan, R is a hot wire (24v) and C is a common. By connecting R and C, a direct short is created. Most likely your 3 amp fuse is blown. It should be in the furnace control board. After you replace the fuse or reset the little 3 amp breaker, I would watch this video next as to why the blower is not coming on: ruclips.net/video/JSgLGTAbDF8/видео.html
Word of Advice TV , you are the best...nailed it! Thanks for the help!
just hot wired the thermostat and the furnace works. Thank you.
You sir are a wealth of knowledge! I'm subbed! I am having these issues at present and came across your channel and have been watching the videos you posted. My furnace just started short cycling recently and I am trying to troubleshoot it with out calling for repair but that option isn't off the table. I have a lennox elite g50uh. I don't have the on/off switch at the furnace so I have to trip the breaker. I cleaned the flame sensor though it really didn't look that dirty as compared to what the videos have shown it can look like but problem remains. I will replace it since it doesn't cost much and see if that fixes it. Blower fan starts, the igniter lights,, I get flame but it turns itself off. It either turns itself off quickly or turns on but stops shortly thereafter.
I've wanted to replace the thermostat to something a bit more modern (and I'm not sure if this is the problem).
Thank you so much for your videos and advice!
Thanks for putting your info out there, helped me get my furnace going again, for zero dollars out of my pocket. Trouble shooting is the hard part. Swapping parts is easy.
Exactly what I was looking for; thanks, esp. for the excellent camera work. As a bonus, I get to buy a new toy: magnetic jumper; never knew that was a thing.
What a terrific way of explanation 👌
Keep up the good work .
very educative. Thank you regards
You are THE man! Thanks.
A little help is much appreciated! On my board I don't have R by itself and C by itself. I have RC, RH, B, O, Y, W, G
You should look up heat pump thermostat wiring since it seems like that's what you have. Here's a short summary:
RC is power to cooling, RH is power to heating. These two are often jumpered together (internally or with a jumper), as if you only have one R terminal.
O or B is for the reversing valve
O or B is the common. Just look what color wire goes to C in the furnace to confirm.
Y is cooling
W is heat
G is fan
You're right the RC/RH are jumpered together. I followed your advice and when I connected the R and the Y, the AC started running so I have a problem with my thermostat
Expert always nice I love all your videos Jay. Thank you so much.
I liked the way you explained the video. Much easier to understand. I always be watching your HVAC video. It be helping me out. Thanks
Thank you for that info!
Thank you very much for your vídeos, I appreciate it very much !! Just one question to bypass the thermostat should the unit be off? Thanks
It doesn't have to be off. Just be careful not to touch R to C as that would be a direct short and will burn out the fuse.
Thank you for the HVAC thermostat test info.
No problem, thank you for watching!
Such a helpful video, thanks!
Hello and thanks for the help! I need to bypass the 2 speed fan control with capillary on my ancient central air unit until the new switch arrives. Blue,black and red wires. Thank you
You did a fantastic job, explained everything well on what was going on with everything. Used your testing method, fixed my issue. Thank you!

Thanks for sharing the info. The water leaked from the roof on my wall and the thermostat got wet. I thought the unit would start working after drying, but it didn't even after completely drying the unit. I changed the battery as well but it didn't turn on. Does that mean the thermostat has gone bad? The unit is "Honeywell VisionPRO 8000 Programmable Thermostat". Your comment is much appreciated.
Thank you for sharing!
I TRULY APPRECIATE your vid of CONCISE INSTRUCTIONS 👌🔧 😊
Happy to help! :)
Thank you for making these videos.
Well done and thank you for that awesome tip. My unit is not working and your advice, gives me more time to consider options. Great safety comments too, really appreciate you!!
I do have a question, my issue with my AC is I accidentally disconnected the wires from the outdoor unit to the sensor. And the wiring the installer did was to connect to the same outdoor safety switch that brings the line to the load. I can't find any advice on how to reconnect the sensor wires.
This actually worked I used foil as my wire jump
Thank you for your vids - super helpful and appreciated.
I have a problem with no power to my thermostat but power at the board. Happened last night during a rain storm - probably unrelated but not sure why it would just stop working like that.
The breaker is fine and the board is getting power. Thermostat connection reading 27 volts at the board.
I also checked if the the water pump was working or if the float tripped anything but it appears fine.
Any suggestions on what else I should look into?
Regardless, thank you for these vids. Really helps to understand 👍
I would like to say thank you. Your video was easy to understand and very informative. After following the steps you described i was able to determine that i had a faulty thermostat. Once again thank you.
Thanks for all your videos especially this one which showed I had a bad thermostat.
You're welcome! Glad to hear you were able to find what the problem is with my videos :) Stay cool!
Awesome video. It worked. Just one question and it's probably a stupid one. That's all I need to do until they can come fix the thermostat right? It's running now and will continue to run until I flip the switch. Is that a safe way to run it?
Thank you for the great video. I have a question with regard to the bypass. You mentioned that it is better to turn the furnace switch off After you find out if the thermostat is getting power to do the bypass. How can the motherboard gets power to turn on things if you switch the furnace off, am I missing something?
Great video, great help. Thanks
24 v dc or AC thank you Brian
Thanks for the good explanations and making clear the purpose of the various terminals and the wire color code..
Thank you Dude!! Just replace my thermostat and the technician did not do a by pass from R to RC and my AC turned on.
The oil provider ROB here in NY is charging mr for 125 dollars diagnostics and 215 per hour of labor and plus for parts and blah blah blah!!
I just did it my self bypassing..
love the video. There is no power to my thermostat after checking with a meter and all breakers are good. There is power to the outside condenser. Any ideas of what to check next? This is a split system heat pump.
Very cool 😎 Thanks for all your help
Clear and concise.
Great clip my friend
Very helpful . Thanks
Great Videos! Very thorough and clear. I decided that some of those magnetic jumpers would have come in handy a few times so I ordered some. I was glad i thought to see if you had a link for them, which you did, so I cleared my cart and used your link instead. You deserve the support even if it is only a little.
Thank you so much for your explanation! You saved me a service call at the very least and possibly being upsold into a new system. My confidence level has risen!
Great instruction! Clear and concise!
If you have gas heat, you only jumper red to white as the white call will energize heat and the fan without green being jumped. Because gas heat fires the gas first while delaying the fan, the fan will be brought on by time delay. if you have a heat pump, wire red,green,yellow,orange....those four together will call for the indoor fan, the compressor and the reversing valve.
So if a thermostat isnt energizing G on the thermostat side. Can I bypass it by wiring G to C? Or do I have to jumper G to energize with cooling/heating respectively based on season?
Nice. Next time dont add your 2 cents. Make your own videos. If your not willing to answer questions dont act like you care.
Rob, thank you for adding your two cents. It was appreciated and I don’t have any emotional connection to whether you care about me or not… (like Others.)
Where did the orange wire come from?
just what i needed. thanks so much!
Fantastic. Very informative.
What's up Jay? Thanks so much for your videos. They helped so much in my troubleshooting skills.
You're welcome! Thank you for watching :) Glad to hear they are helping with troubleshooting!
Very good info!
Thank you sir. Now I subscribed you. Its worked.👍👍👍
My AC turns on and cools the house, but DOESN'T turn back on to cool the house again when it heats up again. Any idea what that can be from? Thank you for taking your time to read this and your videos are great!
Sounds like something is wrong with the thermostat. If it has batteries I would try replacing them first. If problem persists, then likely the thermostat is defective. Only way to check for sure would be to check voltages in the furnace with a meter.
@@WordofAdviceTV Thank you for the reply first off! I'm gonna swap out the batteries tonight and most likely purchase a new smart thermostat in the very near future.
@@jodeci888 Sounds like a plan. Good luck, stay cool! ;)
Thank you again.
