Alone grandmother needs help: AC intermittent

I am by myself expecting 4 small grandchildren in 2 hours. Airstream is in a campground. I came down yesterday and AC would not work. We have a Dometic Duo Therm with modes of fan, cool, heat pump and furnace. I have a local repairman come. He reset the circuit breakers, took off the interior cover and cleaned the filters. Air was working fine when he left. It was a cool day so I turned off the AC and left for a few hours. When I returned AC circuit breaker was off. I turned off the master and all other breakers (AC, hot water and one circuit with a white rectangular button) I turned them back on. Still have a problem. The zone 1 ( there is only one) is flashing and the air coming out starts out cool and then withing a minute turns very warm. I have the mode setting on cool and the fan on auto. Any suggestions as the repairman doesn't work on Saturdays.

It might be the campground power supply is overloaded because of hot weather and too many air conditioners running. This can lower the voltage you are getting, thereby increasing current and tripping the breaker. Can you have the voltage at your power pedestal checked?

Sorry you are having trouble. I agree with Doug, Have power/Amperage checked under load at the pedestal. If you have access to a good 30 AMP generator, try that.
