GFI outlets

did you reset the GFI controlling those outlets? Should be receptacle with a test and reset button on it... might be hidden somewhere, like behind a tv or bathroom.

Check your circuit breakers and fuses.

Moved to Tech Issues forum from 5th wheels.

You can get a tester for outlets at your local hardware store, get one with the GFI test button. I've had to replace a GFI once.

Use a know good appliance plugged in to receptacle. If it does not work, push the test button. It should pop out. Then try to reset by pushing that button. If it does nothing, there is no power to GFCI.
Are you connected to shore power? GFCI only work on 120 volt system, either shore power or genset.
Reset circuit breakers. Turn all off applying light pressure toward off. Turn on main breaker, if equipped,, followed by branch breakers one at a time. Test receptacles with know good 120 volt item.

There is a breaker for the GFI inside the converter.

Even if it does not look tripped flip it off and then back on. If its not clearly marked turn 'all' the breakers on and then back on. Those breakers just don't always click off all the way, I've had that problem.

The other problem can be a bad GFI. These darn things look like they are ok and the switch goes on and off but they are broke. They get tired and need to be replaced.

I still bet its the converter breaker though since both are not working.

Just replaced ours for the 2nd time in 8 years, they wear out.

Common "none of my GFCI" causes
If none of them work, first check the GFCI itself, is it "Tripped", If so reset, does it trip again,, See below.
Now check the circuit breaker feeding it.. Is it tripped, Reset. If it trips again, see below
NOTE: in some cases the Circuit breaker may be the GFCI...

NOTE 2: IF YOU HAVE AN INVERTER... Then you have one of two configuratrions
Factory installed inverters typically have circuit breakers,, usually 2, sometimes more. on the inverter itself.. Now modern design practice is to place them on the rear where you need a flashlight, 4 hands and a mirror to find 'em so you can imagine my surprise when I went to help a fellow RVer and they were right there on the front in plain sight.

After market inverters.. May be like that,,, Or they may have a SUB PANEL inside the RV, usually near (mine is behind) the main breaker panel.

Tripped breaker prevents reset

Finaly note before we get to "Below"
A GFCI that trips immed on reset .. the sound is different than a "no power" attempt to reset,, Kind of a double click sound if it's tripping.


Below
If either the circuit breaker or the GFCI outlet is tripping.. First UNPLUG EVERYTHING that is plugged into a GFCI outlet.. if the Fridge does not work UNPLUG it (Plug is outside in the fridge access compartment)

If this fixes it plug in one at a time till CLICK it stops (HInt a night light in any affected outlet will show you quickly when it clicks)

If a GFCI still trips with everything unplugged... Check 1st the patio outlet,, Often the seal crachk, i tfills with water, and CLICK goes the GFCI.

If any GFCI outlets are in slides
under the slide are two junction boxes... I've heard of one (or both) of them getting filled with water and .. See last paragraph.
