We had a recent freeze for several days and shortly after our upstairs thermostat completely went blank. I tried unplugging it from the wall and resetting the breaker but nothing worked. The A/C repairman came out today and went up into the attic. There is a small light switch on a post that says "Heat". It had been turned off. Turning it on was all it took to make the thermostat work.
The strange thing is that neither Hubs nor I have been in the attic for months! The repairman said there is no way it could have been tripped during freeze. We have a small screen that is loose in the attic and we think we have the occasional raccoon that gets in there. Could a raccoon have turned it off?! There is truly no other explanation unless we have a ghost.
