GFCI question
Our Dometic refrigerator is popping GFCI breakers when it runs on 120 volts. I pulled the heating element and it has three leads, one of which is the ground. Connecting these directly to a GFCI circ...

To answer the questions about the GFCI outlet/breaker - three different GFCI protected devices have tripped. One in the 110 outlet at the campground. I disconnected from that and went to the 30A campground outlet (with no GFCI protection)and the GFCI in my RV tripped. The refrigerator is plugged into that circuit. Finally, when I brought it home, I plugged it into a GFCI protected outlet and the home outlet is tripping. Clearly it is not a problem with the GFCI outlet/breaker.
I suppose it could be a very minimal ground fault. I know the GFCI breaker is supposed to trip at 5 mA, but using ohms law, (Volts = Amps x ohms) at 110V and .005A a resistance of 22,000 ohms could trip it. I don't know what the specs on my Fluke meter is but perhaps at 22,000 ohms it reads "infinite"? That is the only explanation that makes any sense to me. In any case, I'll have it replaced when the part arrives and we'll see what happens.
Thanks all!
