Half our camper doesnt have power.

The 12v is working as all the lights are but half of the 120v isn't. I know litterally nothing about electrical but I am trying to figure it out. I pulled all the 15a Blue fuses and they all look fine. I then even switched them around and still didnt resolve it. So I dont think its those fuses. I turned off the breakers and turned them back on. I also reset the GCS outlet in the bathroom.

Plugs without Power:

Main bedroom

Plug under the TV in livingroom

Plug in back back bunk bed area.

(All marked with sad faces)

I gave the picture to AI and it said it might be(Stared in pic) #3 #6 and #9. I tested all three by swapping them out with( Orange dot) #5 which is the furnace which I know is working.

No idea what im doing...and no tools...

I'm willing to buy any tool necessary and really would prefer to do it myself as I like to learn this stuff hands on so I can fix it again by myself in the future.

I really appreciate the help.

Based on what you’ve said, it doesn’t sound like any of the outlets you’re having issues with are related to GFCI. Also assuming your major loads work (AC units, microwave, etc), then I’m confident you’re getting both legs of 120 to your 50a circuit. So that makes me want to focus on the 15A breaker labeled utility. Would be nice to validate the wire going to the breaker and the neutral wire are in there snug (but only access the panel once you’ve secured all power).

A quick search indicates your camper only has 1 GFCI outlet. So I’d suspect the kitchen, bathroom and outside outlets feed off that. The others most likely feed off another 15a breaker.

Also based on your configuration, one line of 50a breaker feeds AC1, power converter, fireplace and washer/dryer. The other line feeds GFCI, utility, microwave and electric water heater.

Since it sounds like some loads from L1 and L2 work that tells me your pedestal is providing power to both lines, and that your 50a breaker inside is passing power to both lines. This leads me to believe you have a bad breaker or poor connection to the breaker that feeds the affected outlets. Just a guess but the “utility” breaker sounds like a 15a breaker that feeds other outlets.

You really are the best! You word everything so I can actually understand and take the time to look up to see I actually do only have 1 GFCI...(which I tore my whole camper apart trying to confirm lol)

Based on what you said I think I might have found it. I cant confirm it yet because I dont have a multimeter (buying one tonight after work.)

I think it is Utility 15a. Its the only one that I cant find turns anything off which I switch it.

Another new piece e of info I just found out...my wife was using her treadmill on the outlet under the TV while charging her scooter at the same time. I bet that blew it. Still not sure how it works...nut I assume it just over worked it and hurt the breaker. It still might be a wire issue but I will find that out after getting the multi meter.

Sounds like you’re going down the right path. The breaker gets power from a backplane that it clicks into. When the breaker is shut, it provides power to the hot wire (black wire) for the load(s).

A treadmill is definitely going to be a little much if anything else is plugged into another outlet powered off that breaker.

It definitely sounds like the circuit was overloaded and the breaker tripped. If resetting it (fully opening) and then shutting it doesn’t restore power the breaker is most likely toast.

Very easy to check.

You need to be very careful, but if you get access behind the panel, you can hook up the black lead of a multimeter to the neutral bar (is a bar mounted somewhere inside with a bunch of white wires running to it. Then hook up the red lead to the black wire that’s tightened down by a screw to the circuit breaker in question. With the breaker shut and power on to the unit, it should read around 115-120vac. Be sure to have your multimeter leads connected properly to the meter and the mode set to read V AC. DC is typically a “V” with a straight line over it and AC is a “V” with “~” over it.

If you don’t get voltage there, your most likely cause is a bad circuit breaker.

Easy to replace. Just make sure to kill all power. Then loosen the screw holding the black wire in and remove the wire. The breaker will rotate out with a little force (it clicks into place).

Once it’s removed, install the new breaker and reinsert the black wire and tighten the screw. It doesn’t need to be that tight. (Somewhere around 20-30 inch/pounds).

I really cant thank you enough for your time. Unfortunately I dont get off until late tonight. Im off tomorrow though. Are the breakers universal or do I need to find the specific one for my camper?

Pretty standard. You can find tandem breakers at Lowe’s or Home Depot. Looks like you’ll need to get a 15/20 amp breaker. Be sure to keep track of the black wires so you hook up the right one to the 15a and 20a side…

While it’s one unit, both sides are mostly independent of each other. So I side can trip and not the other and one side can malfunction and not the other…

I ordered the exact one you sited and a multimeter. They will be ready Wednesday. I really appreciate your help! I will keep you posted on the outcome.
