Fantastic Fans won't run...

[nagorider]

2012 25' Cloud...the fans open and close, but the motor does NOT turn either of the roof fans...circuits, fuses, etc are fine. Popped the screens to ensure nothing was binding the blades and they turn freely by hand..thoughts??
Heading to Yellowstone this week so probably won't be needing the fans much, but....

Fans only run with the doors open. Power to fan verified? Switch turned on?

Where is the thermostat set? If it's over in the red they likely won't run.

Check the thermostat knob on the Fantastic Vent. If the knob temp is set too high the lid will open but the fan will stay off. Hope this helps.

Check IN/OUT switch; also, make sure fan speed dial switch is NOT turned to OFF. I think there is a fuse in the bezel; but if OPEN/CLOSE motor works, this is probably OK. Also, lid must be opened about halfway or more for fan motor to run. If you only have the lid opened an inch or two, the fan motor will not run.

All of the above are sound advice. If all else fails, call Fantastic Vent at this number: 800-521-0298 and they will be very happy to help you troubleshoot the problem in real time, while you're standing in your coach. Very nice, helpful people. They are in Michigan, currently on Eastern Daylight Time.

Try opening the lid, and wiggling the cutoff switch that turns the fan off when the lid closes.90+% of the time, the switch isn't making contact, and the motor won't run.

I also have a similar problem but with only one fan. The lid opens the temp switch is on the cool side. I was on Assateague at the time and the wind was strong so I am wondering if the wind could have damaged it.

Thanks

Anything is possible, but they wind test them to 100+ mph, so it's unlikely.

The wind clearly was not that strong (It did feel that way when I was riding my bike).

As it appeared to be free spinning , it was going in the opposite direction from the one in the back, is it possible something broke in side the fan?

Thanks

That also seems unlikely, since they are reversible. I understand the factory installed ones don't have reverse, but it's just a matter of installing a switch with reverse.

The one I installed has the reverse switch.

No, they spin freely in either direction.

[urnmor]

Umm Now I wonder if the switch is not making contact. I will try one more time and if it does not work I will call the company. I have worked with them before and they were great to work with.

Thanks for all the input...very much appreciated...
I did about everything possible to get the 2 fans to run...its a new trailer, both fans failed to turn, but other functions were intact...it made no sense...so this am I called Fantastic Fans...
Raymond on the other end immediately know what was up...they had gotten a bad batch of switches (weak springs, poor lubrication, missing corrosion resistance) which control the fan motor....he had me pull the screen off...follow the ground wire back to the hinge and feel around for a plunger type switch...at the full extension of my fingers thru the fan and fumbling with the plunger switch, it suddenly sprung up and upon removal of my hand the fan was spinning....OK, way to go Raymond!!
Not so much luck with the fan up front...the plunger is stuck in the down position. I will crawl up there tonight to see if I can't free it up.
Fantastic Fans is sending replacement parts free of charge. It is evidently a very easy fix...famous last words!? We are leaving for Yellowstone on Thursday, so I won't have a permanent fix by then, but at least I can get one of the fans going if needed...
Thanks again for all the input...this forum rocks!!
