So we had an hvac guy come look at it and our contactor had shorted out
and we needed a new one. He replaced it and it’s working great. I would
have someone look at it!
I am having the same problem. We have been using the nest learning
thermostat for 1.5 years and we haven’t changed anything. But we went to
turn on the AC today and it isn’t working. We haven’t changed the wiring
since the day we put it on.
