We plugged the 30a plug into a 220 outlet, it should have been into a 110 with an adapter. Do we to replace the converter or is there a fuse or something simpler to replace. First time on here, glad to get the help. Dave
Hard to say, you haven't given us any info to go on at all - make, model, year of camper or converter make / model. If it's a recent model converter you may have gotten lucky and simply blown a fuse, if an older model it's likely toast.
30 amp you probably pooped the breaker in the AC side of the power center in the camper. Check all of them.
The model of the converter is wf-8735-p, I've searched the internet and can't find anything. Have checked all the breakers, all fuses are good. When plugged into 110v, all the some things works (A/C, microwave) but no the DC stuff (lights, slides, water pump). But when we switch to the batteries, the DC things work. It seems like the converter is not converting when plugged into the AC side.
Sounds like its toast. If you do decide that you need one, I have a new one still in the box,,,,for half price, with buyer paying for the ride
Since it costs nothing to look - Look for a fuse inside the Converter (aside from the circuit breaker) - maybe like in the photo (an old Centurion converter, since removed from the Aliner, and replaced)
Is it this one? if so here is the manual https://wfcoelectronics.com/wp-content/uploads/2019/06/8700-Series-Manual-web.pdf It looks like there are two 20 amp fuses inside for the DC. I would check and replace them like Anthony Hitchings said it costs nothing to check. I would also check the fuse at the battery too.
I've been inside my WFCO because the large ceramic resistors broke off due to road vibrations (seems to be a relatively common problem looking at the amazon reviews). Be very careful as the large electrolytic capacitors may still hold a charge (they sure were for me). You can discharge them by shorting them with a screwdriver. Pretty sure there are some glass fuses on the board. But I'm not sure they would blow before another component when the wrong voltage was applied.
