Two going out at once makes me think of a power surge. Do you have a Watch Dog on the RV?

If it didn't blow, then it could be the breaker to the AC circuit. Also, check power to the thermostat.

Also, I'm not sure if newer RV'S use GFCI recepticals ahead of the AC unit. That wouldn't have been done on the RV'S I used to build. I would check that. Is the RV 30 or 50 amp?

With a Watch Dog it should cut all power. Without, you can lose one leg and it may be the one that powers AC units.

Man, that check was so basic that I missed it. Thanks. You nailed the best question. Are any 110 volt outlets working?

One of the quickest things you can try for major AC systems electrical loss is to go through resetting the circuit breakers - ALL OF Them. Start with the shorepower breaker at the park pedestal, then the mains breakers on the indoor AC breaker panel, then all of the branch breakers on the indoor AC panel. Switch each breaker completely OFF then back to the full ON position. Some tripped breakers only move slightly from the ON position and can fool you visually. This is a pretty quick check of the most common cause of loss of AC electrical power in the RV.
