OK.....I should have known that my Fantastic Vent had a problem when the PO boasted that he was giving me a new fan, still in the box! Today, my fan went KAPUT! Vent will open but the fan will not run. Soooooo, I'm thinking that I need to install the new one or maybe find a blown fuse?.....but, I've looked everywhere and I don't have an owners manual or installation manual. Checked the website and no luck. My question is....since I already have one installed, is there some simple EASY way to do this? For instance, do I need to go on top and scrape the sealant from around the old one to install the new one? UGH! Rook

Anybody got a Fantastic Vent Fan wiring diagram? Rook

Since the vent opens you know you have power. The fan switch is actually under the cover. If you go up on the roof after opening the cover you will be able to see it on the hinge side of the cover. You may need to remove a screw from metal bracket that the lift arm rides in so that you can disconnect the lift arm and open the cover all the way to make access to the nut easier. Try tightening the nut on that switch with the cover open. Watch your fingers in case the fan starts turning. I had a similar problem and this is what Fantastic Vent tech told me to try. You can over tighten the nut and the fan motor won't start either. So perhaps the nut needs to be loosened slightly.

After this if the fan still does not come on, call Fantastic Vent. They are indeed fantastic to work with and will help you: guaranteed.

You won't have to remove the caulk. The case that is caulked does not need to be replaced if you need to replace all the guts. This is not a difficult task. But talk to Fantastic Vent technicians first.

I would echo the tightening of the nut on the lift switch. I had this exact problem and according to Fantastic Fan, the nut gets a bit of corrosion on it and the contact is lost.

I was able to remove the screen, be SURE the fan speed switch is set to OFF, then using a small wrench, I was able to tighten the nut -- it just took a bit, perhaps 1/8 turn, and then all was well.

Fantastic fan folks are great -- if this doesn't do it, call them and they will help.

Fantastic Vent Fans are guaranteed for life. Just call the company and tell them what happened. Fix the one that is in there because it is easier. Save the new one for later or sell it.They will give you technical support and send you any part you need absolutely free of charge. Over the years I have had three failures in two MH and have always replaced the parts free. They are a great company.

I got the fan fixed! It was NOT the lift switch. The lead that supplies the 12V to the fan motor had slipped off the spade lug connection on the larger circuit board. It was a bugger to find and very difficult to get back on the lug, working overhead. I finally gave up getting the fan blade off the motor shaft so I could easily clean it. I did get the 3-32 allen set screw loose but the blade was frozen to the shaft and I simply could not get any leverage on it. This would have been a much easier job if I could have gotten on top of the coach.The tech at Fan-tastic Vents was very helpful.

Thanks for all the suggestions. Rook

You need NOT remove the fan blades from the motor to clean them. Take the entire motor/blade assembly out together (four screws from the top/outside) and dunk then entire unit in water and clean. YES, the Fantastic Fan motors are sealed and this is the way to clean them - per Fantastic Fan. They also recommend coating the blades with 303 to make future cleanings even easier.

Yep, that would have been easier, but at 76 years old, about 30 lbs overweight and legs and feet about gone......it doesn't seem wise to get on top of the coach! Actually, I can get up there and down......but it's the getting up from off my knees, with nothing to pull up on that's the killer!
