Greetings all, I have a Marine Air 16000 Btu reverse cycle unit that runs and cools great. I have noticed in the past few months that every once in awhile (once a month) the unit will trip the main breaker in the panel. I cleaned the.unit and have great water flow. I looked in the archives but didn't find my particular issue. It does not trip instantly. Any one have ideas of how to trouble shoot?
