Now THIS is really strange!

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.
 
Yes, we have a small screen in the attic that has come loose. I've been looking for a handyman that can fix it with no success. :(
You might want to nail a piece of 1/4" plyboard over it for now. Leave a gap or drill a few holes in it smaller than the width of a finger if ventilation is absolutely necessary.

Now you're in my shoes---wondering how this thing got moved or something ended up on the floor. Or why at nearly 4am someone knocks on my exterior door with 3 raps...or why the shower head was on one evening and I hadn't used it...or or or
Does seem hard to figure your switch thing out especially up in the attic where you don't use. Put a game camera on a post or nearby and check on it from time to time.
 
Now that the thermostat is working, I would flip the switch off and see if it continues working.

It’s far fetched but maybe the thermostat was fine until it went out and somehow needed that switch in the on position to give it a jolt.

Otherwise, I believe that a human somehow tripped the switch and it simply doesn’t ring any bells.

Occam's Razor, the principle that the simplest explanation with the fewest assumptions is usually the best one.

Darn varmits! 😁
 
Yeah, a racoon sounds like the most plausible explanation. It was extremely cold, and they are pretty clever at getting into places, especially when they may be seeking warmth. They have dexterous, hand‑like paws, curiosity about anything sticking out, dangling, or protruding, and a habit of testing objects to see if they move or open. There are plenty of stories of raccoons opening latches, turning knobs, flipping, switches, and unscrewing vent covers.

The curious thing to me is why that switch is up in the attic.
 
Is it a physical switch? Like a light switch or toggle switch? Or a push button electronic switch?

If it's an electronic switch sometimes a power disruption can cause a hiccup, think of your clock radio. I can easily understand the switch needing to be reset after a power fault.

If it's a physical switch I'd blame your husband, typical married couple arguing over the temperature. He probably thought he could be sneaky and shut the heat off without you catching on.😝

The actual A/C units are outside, but the venting is in the attic. So are the two water heaters.

It's like a light switch that is stuck on a vertical beam. It's just screwed on there. Couldn't be hubs because he spends most of his time upstairs and that's the thermostat that shut off. If anything, I'd be the one! :ROFLMAO:
