The confusing part of this is 1) that both thermostats' displays disappeared (even though only one was powered up) and 2) that the power to both was restored without any intervention on my part.

Last week was the first trip of the season where I had the A/C on. The outside temp was 70ºF and 30% humidity but after a while it got up to 80ºF inside. So I turned on the front unit. It cooled for several hours, running normally, then just stopped. I checked the breaker panel, nothing tripped. I checked the 50 amp on the pedestal. No problem there. Both the front and rear thermostats displays were out, nothing showed. After about an hour, the displays reappeared and the air conditioner worked. What would cause this? 2000 Monaco Dynasty
