I have always been wondering about that issue with my 323. When I turn the refrigerator on, the compressor runs 100% of the time. My thought was that it was due to nonexistent insulation around the box, and lack of air flow around the compressor. It's been that way since the boat was first launched in 2005. I never did anything about it. The root cause could-be as simple as low refrigerant. I have no Idea what kind of refrigerant it uses, nor have I been able to locate a recharge port. Subsequently, the refrigerator has never really been used, the stove has never been lit, and the microwave has never been used... Everything stays pretty clean that way. Beer and boats don't mix anyway.
