Norcold 3 Way Trips GFCI on Shore Power

Gherzig

I spent my first 4 days with my new to me 2021 Tab 400 testing out all the systems in my backyard.  The one issue (so far) which I am unable to figure out deals with the Norcold 3 Way fridge.  It works fine on propane but trips the house outlet gfci when on shore power.  I have it connected to a 15 amp outlet.  I ran it on propane for about 30 minutes and all went well.  I then switched to 15 amp shore power and the gfci tripped after about 15 minutes.  I tried other outlets and they all tripped immediately upon plug in. I tried a diffract cord and adapter, same result.  Would seem like a short somewhere but I would not know where to begin to look. Thank you.

Are you running any other appliances off of shore power while running the fridge?  Like the Alde and or AC.  If so that may trip the breaker.

It is not the breaker being tripped.  It is the GFCI.

Possibly a mis-wired outlet (use an outlet testing plug) or a defective GFCI.

Unfortunately I tried other outlets with the same result.

Plug the refrigerator into an extension cord and bypass the camper completely. If you have the ability to measure the amperage draw, that may reveal an issue with the refrigerator itself.

Is there some sort of EMS gizmo in the circuit ? They can trip up GFCI (pun intended).
