Unhappy Electrical blowing house ground fault

We plug in our No Bo 19.5 to our house 20 amp to get refrigerator cooled for the next trip. Tonight the ground fault is blowing every time we plug in the No Bo. This has not happened before.

Nothing is on in the camper, we have not turned the refrig on yet.

We checked our house circuit breaker and reset each. No difference
We used a different extension cord from camper to house. No difference

What else could be causing this?

Have you used this outlet before to power your No bo? Gfi outlets don't always get along with campers.

either move the cord to a non GFCI protected receptacle in the house

or

turn off the gfci circuit breaker in the trailer

or

run the extension cord directly from the house to the refrigerator

electrical problem

Valley duo - yes, this is the same outlet. We tried other exterior outlets with same result.

Chickdoe - We moved cord to non gfci protected and electricity stays on but were advised to not leave it this way over night.

If it is the gfci circuit breaker do we just buy a new one to replace it -- do these things go bad often?

Thanks, I really appreciate your help

electrical problem

Another perspective -- just for future reference

Just spoke with another person who has experienced this with his camper. A tiny speck of moisture in the 30 Amp receptacle on the camper can cause this to happen.

On the 19.5, the outside shower is directly above the electrical input, the spout for water from the roof drips directly down to it, and I think a water input is directly above it.

Right now we are taking it out of the camper, drying all parts then will put back together and caulk it all around. Hope this works and solves the problem

The GFCI breaker is not bad. The issue is the way they work. Some of the inexpensive GFCI breakers will appear to a good one in the same circuit as a fault. Try turning off the breaker in the distribution panel that controls the GFCI protected outlets ( bathroom etc) in the RV. This should be a different circuit than the fridge is on. If you can not do this. There is nothing wrong with being plugged into a non gfci outlet in the house. The large breaker in the campground pedestal is not GFCI protected.

Chickdoe, I asked a friend who is a mechanical engineer. He does not claim to be an expert but suggests we not leave it plugged in overnight as a precaution. Like maybe a fire could start while we're asleep. I didn't ask a lot of questions of him

GFCIs are designed to prevent electrical shocks to humans. Circuit breakers are designed to protect wiring against shorts and overloads. You are still going through the circuit breaker in you home panel. GFCIs do not prevent fires.
