1994 u240 bathroom fan not working

Are all rv bathroom fans interchangeable? The motor quit working. Can I just replace the motor or?

You should be able to replace the motor.

Nowadays they're a standard size, 14" x 14" I believe. I can't speak to what's in your 94.

I was able to find a replacement motor on etrailer.com on my last rig. I've also had the control board go out in one... wasn't able to fix that but managed to bypass it completely and just wire a switch in.

Is the vent open all the way? I seem to remember someone having a vent switch and if closed the fan wouldn't run.

14" by 14" is the standard hole.  My bathroom fan has a magnetic reed switch to prevent you from running the fan with the cover closed.  I just jiggle speed switch.  For now.

I have Dometic Fantastic fans in my bathroom area.  Just need to figure out what you have and do a search. 

Like:  Amazon.com: DOMETIC K8017-00 Fan Blade and Motor Assembly - Standard Vent :...
That's the one that I have!

Brett, do you have a multimeter? Can you use it? If yes to both, start testing before you spend any money.

That's a 12vdc fan, so check that you have 12vdc coming to it. Then follow the wires (or check the schematic) and check at each switch. If power is present all the way, then replace the motor. If one of the switches is bad, replace it and continue.

I have found many times that the pin switch that makes the connection when the lid is raised that is the problem.
