Maxx Fan Possessed...or shorted...

[Sisababe]

I think my Maxx fan is possessed! Rain for three days...then a small drip from the fan I thought was condensation...now the fan is tweeting trying to turn on by itself intermittently for hours ...sounds like morse code... but won't respond to direct or remote commands...suggestions?

Easiest and quickest for tonight is to pull the fuse.

Finding it difficult to figure out which one controlls the fan...only lights, heater, fridge, etc labeled. How do I narrow it down?

There is a fuse in shroud of the fan itself ( mine anyway ). It's somewhere in the vicinity of the other control knobs. Have you got the instruction pamphlet? It's shown there.

I'll dig it out...thanks.

Yours is years later than mine, so I'm only guessing.

Nothing in the manual beyond operation but I opened it up and disconnected one of the harnesses and that seemed to do the trick.. all quiet...Thanks so much. I need my beauty rest! I'll contact Rease for replacement/repair instructions.

Found a picture of mine in my archive. It's the round button next to "in" and "out" switch. Unscrews and a glass fuse tube falls out and lands on the floor.

As you suspected the glass fuse is only on the old fan design. No removable fuse on the newer ones. Manual says this: "This MAXXFAN incorporates a self-resetting fuse on the circuit board located in the ceiling assembly. It can be reset by removing and re-applying power. If your fan fails to operate or needs reset, contact Customer Service at 316-832-4357 for assistance or solicit the aid of an electrical technician."

Sisababe: My suggestion would be to plug the circuit board back in. Pull and reinstall all 12V fuses or if disconnected from shore power simply throw the battery disconnect switch. This ensures power was killed to the fan. Then try the fan again. If it is still acting strangely it is probably a bad circuit board. If water did somehow get in and killed it you'll need to figure out why or the same thing will happen to a new board. I attached the circuit board part numbers for your reference, but it depends on which fan model you have. Since your trailer is so new and possibly still under warranty speaking to ETI is a good first step.
