AC Unit Question (fan/cool)

[Skins44]

Hello all. I have a 27' Outback. AC unit runs well, however occasionally to be on the safe side i power it off to use the microwave or wife needs the blow dryer. I have 30 amp and the hair dryer will trip the breaker almost every time.

My question, when i put the thermostat back to "cool" the AC doesn't always kick back on. I have to put it on "fan" for about 15-20 seconds, then flip it to cool.

Is this normal?
