27 FT Holiday Rambler

I went back out to the camper a few hours later last night and it was down to 64 degrees inside. I set the thermostat up to 66* so it would kick off. I then set it lower again to see if it would kick back on. The Cool On icon just flashed again and nothing happened. Maybe it's because I'm trying to turn it back on too soon and there's some kind of safety built into it? But that wouldn't explain why it did that the first time, before the AC kicked on...

I know my home thermostat does have a time out on the AC control so it will give the compressor about 15 minutes to bleed off before attemping to restart. Apparently you can smoke a compressor if you try to restart it while it still had residual pressure?

Yeah, when the pressure is still there, the startup surge is fighting a really bad dead-head on already hot windings, and it is pretty tortuous on a compressor. Once or twice isn't terrible, but if it happens regularly its a death sentence. I don't think my RV AC has that, but it usually just trips the breaker if it hasn't sat for at least a couple minutes.

This evening when I get home, I'll kick on the AC so it can cool down a bit, then set the temp warm enough for it to kick off. But this time I'll just leave it sit and see what happens.

My other camper still has the original Duo-Therm thermostat. It's not digital. On that one, when the thermostat cycles, the AC unit stays running but the blower kicks off. I don't know if that's how it's supposed to be, or if it’s got something wrong too.
