I have a 2004 Larson Cabrio 240 which has the factory installed air conditioning system made by Anchor Marine Comfort Systems. It has always worked great. We put the boat in a slip Friday night and turned on the AC, which cooled the cabin right down. However, when we came back Saturday morning it was blowing warm. I have cleaned the strainer, and it is pumping water out like it should. I checked the two fuses on the control box and they are fine. I turned it to heat and that works. Left it off for 24 hours in case it was frozen up but that didn't help either. Any other ideas before I have to pay someone to come look at it?
