Hi joanbryant,
First, let me assume you don't have factory installed solar because the power setup is a bit different.
The output of the inverter that supplies power to the refrigerator (through a small transfer switch), has a GFCI outlet.
So the first question is, when you lose inverter power, does that GFCI outlet need to be reset on the inverter, or can you just press the Magnum Remote button inside the coach to start it again?
If the remote starts it, you may need to check for error codes on the inverter. There's a code display on the surface where the GFCI outlet is located (#4 in the drawing at the bottom).
