The refrigerator in my boat is not feeling well. The compressor and fan run for about 3 seconds, and then it shuts down. Every minute or so it tries to restart with the same 3 second run and shut off. This is a Nova Kool RFU8000DC running on 12 volts DC. I checked on the web, this little fridge costs almost 2,000 bucks! Ouch. Anybody have a clue why it does this? Fred Tug 44
