Have a bathroom fanTastic fan which has a 12v motor on it like this...

Fan Tastic Fan

I replaced the motor lift assembly about 3 months ago and fan worked fine opening and closing cover after flipping the switch... about 2 weeks ago I went to open the vent and the motor turned the knob about 3 turns and the vent opened about a inch or so and stopped. I had to turn the knob manually to open vent and have fan turn on. when I flipped the switch to close it nothing happened. Had to be closed manually... Same thing happens every time I go to use the fan...
I have 12 volts to the motor and thats about all I checked. Any suggestions as to what else could be wrong or what to check for?? I don't see any obstructions or anything in the way. The trailer is in the same location when the motor worked and when it stopped.
Thanks for any help.

There is a cutout switch that turns off the fan when the cover is closed.
That switch goes bad sometimes.
It may or may not have something to do with your problem.
It is a pin that gets pressed down by the cover when it is lowered. Fairly easy to bypass temporarily for testing purposes.
But tbh your description sounds more like an overload issue with the lift motor. Have you tried to grease the lift assembly? Or maybe something has become unaligned, a screw turned loose or something, and now the motor does not have enough power after the first turns? If that is the reason, and you crank it up further manually, I would expect the motor to not be able to crank it down either.

This happens to mine every once in a while, that pin switch sticks or has enough dirt and corrosion on it so it does not make contact. All I have to do to un-stick it is open and close the lid manually a couple inches a few times and it starts working again.

If that does not work, if you remove the screen, feel around for the switch and push it up and down a few times. Make sure to turn the fan off first [emoticon]

Please let us know what you figure out.

Thanks for the response, Is that pin on the lift assembly or somewhere else? will try some grease also. thanks

the switch u r talking about is that the same pin that the above poster talked about??? if so than u are saying its not on the lift motor itself but somewhere around the rim where the screen is?
thanks

The pin is in the upper surface of the fan housing, the side that faces the cover.
When the cover is lowered, it depresses the switch pin and cuts power to the fan to prevent it from running with the cover closed.
But your issue is with the lift motor, not with the fan itself, right?
I am not sure if that cutout switch has any connection to the circuit of the lift assembly. I just mentioned it as it is the one thing that gives problems pretty frequently.
Like I said before, your description sounds more like the lift motor is getting overloaded. But I have never had that type of Fantastic Fan myself, only the manual lift version.

Went out today again and tried it and when I go to open it the same thing happens. it turns about 2 turns and stops and the vent is open about a inch. I crank it up manually to the full open position and the fan turns on... when I went to close it the lift motor did turn and lowered the dome to about 3 ins from being completely closed and than just stops. Have to close it all the way manually... Just seems like the lift motor is struggling and very slow...... Maybe I got a bad motor and there are no returns or guarantee on them.
Any other suggestions or ideas.
THANKS AGAIN.

Almost sounds like a lubrication issue

The Pin switch people are talking about turns the FAN motor off if the lid is closed. DO not know (Since I don't have that model) if it has anything to do with the lift motor.

until you take the lift motor out and see what is wrong with it you will not know. did it get wet? is it hard to crank up manually?
here is a replacement one one that has a video talking about it Replacement Lift Motor for Fan-Tastic Vent
