I have an issue with the heat side of the Marine Air in my 95' 330 Sundancer. When I turn on the heat, everything starts up normally. Good water flow, clean filter, compressor starts right up and sounds good, and fan runs. I usually set the fan to run on 6, but the problem happens either on auto or on manual. Before the cabin gets up to temp. the unit shuts down, and the display flashes between --- and the set temperature. The sound that it makes at shutdown is as if you would shut the power off while the unit was running...a large depressuring sound. The breaker does not trip, and the fan keeps running if I have set it in manual at 6. It will eventually start back up on its own and continue to heat for maybe 2 or 3 minutes, then does the same thing. It will eventually get the cabin up to temp, but it takes quite some time. By the time I get this fixed, I probably won't need heat any more, but fall will be here quicker than I think if I don't get this resolved soon.

I am going to try and find someone in the area that will work on marine air units, but I thought I would throw it out here to maybe get some ideas or directions to look for.

Forgot to mention that this does not happen when the air is running.
