The other night the breaker tripped On the electric panel I’m plugged into so I reset it and my 2 bathroom plugs still are not working and I tried to reset the GFI outlet but it still will not reset. All the fuses are good and no breakers in the 5th wheel are tripped. I ran out of ideas on what it could except for the possibility of the actual GFI plug itself.

Couple of years ago, at the dunes, major rain storm came in from the west.
Door side of the trailer was facing west.
Middle of the night, GFI tripped and I couldn't get it to reset so genny wasn't charging batteries.
In the morning, traced it down to the outlet next to the door had gotten water in it and caused the trip.
Got it all dry and back together, everything worked fine after that.
Just my experience.

GFCI outlets will NOT reset unless there is power coming into it.
