I reread the post.
Sail switch in thermostat if it happens again, needs to be checked.
Failures start of intermittent and then completely. They are like a set of points in an old condenser ignition if a car.
Some people up try to run the ac's on low instead of auto. They freeze up from lack of air volume through the ac. It freezes up and won't do anything sometimes. Sometimes it will kick the breaker.
Other times after all the ice is gone but it may be balky and take a while.
AC in some campgrounds up there we found very low voltage. Sometimes it would start out showing normal voltage and after a fe minutes of high load from several campers or ac's the corroded wiring would heat up and switches would pop or not and low voltage might burn up motors and electronics. If it showing low volts , run your generator instead.
