One possibility, again related to GFI, on our former DP, it had the norcold refrigerator, If I plugged into shore power in storage, a GFI circuit, when the refrigerator was on AC it would trip the GFI, no ac power in the coach except through the inverter. It was fine plugged in at any campsite we stayed, but consistently tripped the GFI in my storage garage. If I left the refrigerator off, all was well. Fortunately the Gemini refrigerator does not have that problem. I never did solve that issue, but we could never leave the refrigerator on while in storage, and running on propane was not an option, since its stored in a closed garage.
