Your problem could lead to a more serious issue. Norcold had a recall some years ago because their units were overheating, leaking cooling fluid and causing fires. Their fix was to install a Thermistor in the power line. You can probably find more info on this at the Norcold website or a google search. There is a class action law suit that they just lost but the time to get in on it has past. I would suggest that you look into your problem deeper and maybe have a technician check out your Norcold frig for the afore mentioned problem.

We need more info about your fuse problem. What exactly is going on when this happens, you know what I mean. Was the generator running, had you just switched over to shore power or generator power. Had yo just turned it on for the beginning of the season. Had you just loaded it up with food. Was it just switched over from gas to electric.
These things need to be know to help you better answer the question. Getting this info will also help you better understand what is going on with the system.
