Front vent fan not shut off
Our 1999 Excella front vent turns on when vent is cranked open. When closing it should shut off and usually does.
On occasion it doesn't shut off. After many crank open/close cycles it will shut off no matter how far I crank open or closed it fails sometimes.
Is there a diagram of the vent or idea from the group on what it might be that is causing!
Thanks in advance!
Peace and Blessings..
