We have a Waeco frig in our 2006 288 Vista that will not get cold on 12v DC but runs perfectly on 110 v shorepower. Our battery configuration is three batteries, one dual purpose battery dedicated to the port engine and one for the starboard engine, and I just replaced the ships system battery with a group 31 Marine/RV deep cycle battery. When on 12v power, the compressor will start and the shut off after 10 seconds or so and you can hear what sounds like a fan running. After a minute or so, the compressor will kick on, run for a short duration and then shut down. While in this cycling mode, the frig stays cool, but not cold and the items in the freezer defrost. It appeared it wasn't getting enough power, but when switching on the port and starboard engine batteries, the result is the same. Anyone have any thoughts on what could be going on? Thanks for your consideration.
