How To Test If You Have A Bad Home Thermostat 

For a beginner like myself, another great video that makes things so simple to understand.. Keep the videos coming professor!

Another great video, Sir. I now am sure that, I am able to trouble shoot the low voLtage circuit, because of you. i actually was able to understand you fully, because of the thoroughness you provided. I doubt it very much, that any one else out there could have explained this with such clarity. Thanks a million. I am in retirement, and I am now positive that I will be able to make some extra income, because of you. Been on a fix income, and barely making ends meet, I now will be able to service heat pumps for friends and relatives, and make some extra money. I thank you from the bottom of my heart SIR. God bless you.

Awesome video very thorough and detailed. Thank you.

🔥💯 OUTSTANDING video and demonstration 💯🔥 Thanks for showing the step by step of this. 🔥 Keep these videos coming. 💯

Great video Mike. Thank you for the knowledge.

It would be great to see a video on how to check how accurate the thermostat reading on the display is, and whether the built-in offset adjustment needs to be configured.

Great teaching on thermostat👍🏼😎

Great info. Thanks Mike.

Excelente video. Thank you.

Great Video 👍

That's fantastic

My in-laws a/c system went down. I discovered that the BACKPLATE for the nest shorted out. this caused the contactor coil to burn out , the fan to stay on and the 3-amp fuse to blow. I removed all the wires from the backplate and everything was fine. New backplate.

thank you Mike. my hvac unit has a nest tstat but i only have a red wire attached to one of my rc/rh terminals. but i have heat or air hows that possible if i only have one red wire attached to only one r terminal? i may have missed my answer in the video.

Thank you! Greatly appreciated. I have the same honeywell tstat and the fan comes on in heating and cooling modes. But when trying to turn on in just fan only on or circulation modes, the fan does not come on. How do I test to see if that is a tstat issue? Thank you!

Is there a video for install nest when there are 2 wires in R spot & then a jumper wire from R to Rc?

Hey again. I wish there was a way to directly message you. I'm still having some issues with my heat, and I need to try to replace the thermostat, or just return it could you please help me figure out how to connect this thermostat from the old mercury one? And potentially do some basic trouble shooting? I'd greatly appreciate it, thanks

For the style that completely pulls off the wall and runs on batteries, can't you test the thermostat itself directly by calling for heat or cool and probing the contacts for continuity? Instead of jumpering the wires in the wall.
