We've been sitting in a campground for 7 days, running the A/C daily until yesterday. About mid-afternoon the thermostat goes dark, no other 12v system blinked and the 110v was working well as we were watching TV.

At first we turned the thermostat off and back on after a minute or so. It lit up and A/C started fine.   The A/c ran for a few more hours than off again. We turned it off again and this time we just reset a circuit breaker as well. The system returned to normal and ran through the night and is fine now.

Of course our RV tech can diagnose unless it's not working... Any suggestions?

Thanks,

Jeff
