Elec Sys Trouble with 5th wheel furnace

[WanderLore]

97 areolite 5th wheel.
Turned on furnace, its propane with a blower. After about 15 mins blower quit and so did 12v lights. AC and electric outlets still work.
We've worked on it and looked online. Checked breakers, cords, etc. Can't seem to find the problem.
It rained pretty good for few days but dry now.
Have an electric heater going and the few outlets and microwave still work.
Unplugged the microwave but that didn't help.
Checked gfi and breakers and plugs.
Anyone have an idea? Hubby says something must have tripped somewhere but can't find it.

Stick a reference thread on main with a link to this one... lots of folks don't use the New Posts button, and don't go to the subforums regularly...

I know you said you checked breakers, but in my camper there is a "secret" fuse panel under the refrigerator. It is located next to the water pump and you have to unscrew a panel to get to it. Other than that, all I can think is maybe there is an inline fuse off the batteries? Good luck!

I think fuses also. under the Frig in my unit - a flop down cover, with automotive fuses controlling the 12v side, with tiny breakers for the 110v side

plugged in = 110v will work from outside source (house, pole, etc) but 12v side works from batteries and its 110v>12v converter. That 12v lights do not work is the primary indication that the 12v side is out of juice.

There is a separate 12 volt power supply that is charged off the 110 volt shore power. It could of been a fuse that tripped or if none of the 12 volt stuff works it might be a bad connection or even the power supply that recharges the batteries might have given up the ghost.

RV electrical, what a nightmare.

Start chasing bundles of wires to find the hidden fuse panel.

There may be a manual reset breaker near the house batteries.

The Atwood and Dometic furnaces in those run off of 12 volts, so if your 12v lights went out at the same time you need to find out why...but that narrows it down quite a bit.
Use a test light on your fuses...often they may appear good but have indeed failed. Replace the blown fuse with one of the same rating and see if it was just a fuse failure...many Chinese fuses are low quality and will fail for no obvious reason.
See if your converter is trying to charge the batteries. If not, carefully check the input voltage...if it is good you may have a failed converter. BTW, some converters use breakers as power switches...cycle them fully off, then on.
Let us know what you find

Also make sure you don't have a ground fault outlet that tripped, killing power to the converter...possibly on the outside.

It turned out to be bad inverter. Hubby hooked up a battery with solar and a charger. It all works great now. Thank you all for your help!
