Customer Question

AC not working, replaced the thermostat Jan. Now the AC isn't working.
JA: I'll do all I can to help. Tell me a bit more about what's going on so we can help you best.
Customer: The AC doesn't turn on. I have checked everything to make sure it was on, the main panel switch is on. The on off switch at the AC unit is on. I only have 4 wires at the thermostat, two red wires (1) is attached to RC the other is attached at R. Then nothing in Y, then I have two white wires, one attached to not used the other is attached to W.
JA: Is there anything else the HVAC Technician should be aware of?

Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am HVAC Guru an extremely experienced tech on the site and I try to get to as many customers as I can. I just picked up your question now. NOTE it takes time for me to type research and add links so please wait for me to respond back I can only do this so fast. Secondly I am not paid anything until you rate my service good using the STAR RATING LINK at the top of your page, the money is paid to the site not me directly.


A wire would have to be attached to Y otherwise the outside unit will not work so I would bet one of the white wires should go to Y...try and see.

All I ask is please use the Star Rating Link at the top of your page before leaving, that is the only way I am paid anything through the are greatly appreciated so thank you very much for using this service. If you have any other questions just post back to me here anytime!
