Hello, I am a relatively new trailer owner and my 120 volt is not working. I carelessly ran a dehumidifier plugged into my 2016 Wildwood / Forest River trailer while attached to an external power source. After several days to a week of running the dehumidifier the 120v system completely stopped operating. None of the breakers were tripped or fuses blown in the panel. The GFCI protected plug doesn't test or reset, so that didn't fix it. Everything that should work when running off the 12v battery works fine. Any thoughts and ideas of where i should be looking or what i might do to figure out where the issue is so I can repair it. Tanks in advance for your ideas, expertise, experience and time.
Best reagards, happy camping

Ok usually the power system lines up someting like this
Circuit breaker----GFCI outlet (1)---GFCI protected Outlet------GFCI Protected outlet ----- (perhaps more)
(1) Usually the GFCI itself is in the bathroom or restroom.
Outlets 2 and 3 are Kitchen and Patio... ONLY the GFCI itself has the buttons. the others are protected by it.
GFCI will not reset: Two or or 2.x common issues
1: Circuit breaker tripped.. they will not reset if the circuit breaker is tripped
NOTE this includes at least two circuit breakers in the park side of your power cord and others.
(Do other 120 volt things work?)
2: The problem that tripped it still exists.
UNPLUG EVERYTHING that is plugged into a GFCI or GFCI protected outlet.. Still "AutoTrips" (Trips as fast as you can reset it).
Check the patio outlet.. The caulking cracks, water enters.. GROUND FAULTs happen.
Next is a wire fault. If you use big ticket items (Some kitchen appliances can draw over 10 amps) that plug in the blasted "unibox" outlets in an RV (That would be the GFCI-Protected ones not the GFCI itself) can melt. Internally that is.
Rodents like the taste of Insulation it seems as well.
And finally.. yes they can go bad.
