I have 16 volts between common and power. Is it the transformer in the furnace? or in the condenser?

[@sinisternightmare405]

New tech here, I was told jumping R and C will short relay? Is that true and why?

Thank you my friend for a very good presentation.

[@yopeacee9472]

Awesome explanation, could you do a guide with maretted connections or is it the same as a terminal block for potential difference? Thanks.

[@kennethlobo4420]

Great explanation.

[@bnappi22]

[@heatherdavidson1667]

I don’t know where the board you are checking is. I know there is one inside the thermostat but that doesn’t seem to be the one you are checking. Is it on the furnace?

[@JumpermanTech]

This board was used as a reference. It could be a board or just a terminal block but the key is to focus on the thermostat cable entering your indoor unit/furnace. Follow that cable inside the indoor unit & you will find the board/terminal block you are looking for👍 Thanks for watching & stay tuned for new videos every week🔧⚡️

So Blue is just common ground?

[@josselindesir5409]

Good job

[@certicare]

I'm a DIY homeowner. Removed old thermostat a while ago for remodeling project. Didn't label anything because it seemed everything was obvious and correct... r to r, w to w, etc. Now, a month later, trying to install new nest thermostat. I'm getting 24 on multimeter for red coupled with each wire, yet thermostat not getting power. Any suggestions??? I've even tried reinstalling the old thermostat and that's not working either.

[@certicare]

No batteries on thermostat btw, powered via c wire

[@AxhuuL]

It all depends on how it’s wired at the furnace/air handler.

[@bigdaddy4975]

The nest needs a battery or a common wire or it won’t work.

[@theastuteangler]

Lol professional homeowners

[@TudyAB]

If the cover is off so is the control board how are you to test wires coming from the wall If the control board is set aside and how can you switch of and on auto/fan if the cover is off. This I find a little confusing, but I think it's me

[@bklynrizz714]

The board he's testing in the video is a supposed to be the control board you'd find inside your blower unit. The thermostat he keeps turning on and off is on the wall in the home.

[@carolconigliaro6130]

Power for the blower on a heat call might come from the sequencer.

[@simohvac9222]

nice video

[@JumpermanTech]

Simoooo! Thank you very much! Your feedback means a lot to me🙏 Stay safe out there & stay tuned for new videos every week!🔧

[@bigdaddy4975]

You can’t check the thermostat when you have the face off and try to operate the unit at the same time.

[@chamindarathnayaka9923]

Good job
