How do I run wire for bath fan?

[wboudx]

Help. My ceiling fan in bath does not work. The problem is the wiring from the 12v DC distribution panel to the fan. I ran a wire across the floor from the same terminal on the distribution panel to the fan and it works. The question is how do I replace the wiring? It looks like it goes back from the fan but no matter which way it goes, I have no idea on how to re-run wire. I have a 2008 Flagstaff 831FKBSS.

Impossible to do as far as I know using the existing wirirng path. Think of trying to replace a wire in your house without tearing all the drywall apart, it would be next to impossible to pull the existing wire through all the curves and places it goes. You will more than likely have to get creative and choose a new path but I don't know how you would keep from having to run it across the ceiling to get it to the fan location.

Did you buy this trailer new? Did it ever work?

Yes, I did buy it new and yes it did work. I think we have used it on every trip and the last trip was 9/11/09. I am getting trailer ready for first trip since then when I noticed the fan did not work.

Your sure there isn't a fuse somewhere that went bad. I find it hard to believe that if it worked at one time that the wiring just went bad somewhere in between. If a wire would have been able to short or something it would have blown a fuse.

Very strange....

Have you tried rewiring with the old wire just to see if for some unknown reason it had a bad connection.

Wires seldom go bad, unless a rodent chews through them. When you ran the wire across the floor to the fan, did you connect it to the switch, or just straight to the fan? Get a voltmeter and verify you don't have 12 volts at the switch, then start worrying about the wire, or looking for a separate fuse. My suggestions anyway. If you don't have a voltmeter, a 12 volt test light will work for this problem. Let me know what you find, there are other steps that can be taken, before you replace the wire.

All trailers are different but here's some things to check.

My bath fan is on a wall switch with the light in the bathroom.
The wall switch needs to be on to use the fan even though
the fan has a switch on it also.

If you have a wall switch, pull it out of the wall and check for
loose or bad connection.
If you have a ceiling light anywhere near the fan pull it off
the ceiling and check for loose connections behind the light.

I'm betting on a loose wire nut behind some other device that's
in the same circuit.
To see what else is in the fan circuit, pull the fuse that powers the
fan and turn everything else ON and see what doesn't work.

Anything that doesn't work needs to be checked for a loose connection behind it.

Pull the fan itself out of the ceiling.
My fan has wires right next to it inside the fan cutout.
There could be loose wires there at the fan inside
the ceiling.

Pulling a new wire is your last resort.
Don't give up yet.

Good luck!

Keep us informed as to what the solution was. Hopefully it is just a loose wire somewhere accessible.

Duh!!!! Do I feel stupid. I spent an hour yesterday trying to figure out this problem. I checked the fuse and checked for voltage at the fan. I also ran a wire across the floor from the DC distribution panel to the fan. All the while, it was the switch on the wall turned off. I even had a label on the switch labeled "Fan",

Thanks for all the replies.

Glad to hear the the problem turned out not to be a problem.

Oh, well..... another happy ending!!!
