Norcold Portable Refridgerator/Freezer

I don't know about the portables, but had a neighbor with a Norcold in her rig. Her husband brought her up for work and dropped her off and headed home. Next day she realized her frige wasn't working. She called a service guy and a local dealer and they both wanted major dollars and just wanted to replace the unit. I looked on line and found a process where you ground a certain terminal and it resets. Worked great for several months until her job was don and she left. A Google search might find you some help and a lot cheaper.
