We purchased our 92 Excella on July 31st 2012. We have two Fan-tastic Vents in our AS. I cleaned them the hard way by reaching in and working around the blades, etc. the first and last time I did a thorough cleaning back in 2012.
This time I used the cleaning guide furnished on the Fan-tastic Vent website, removing the inside trim covers and loosening the 3/32 allen screws that hold the fans on their drive shafts. One blade came off it's drive shaft pretty easily, but the other will not budge. The metal ring in the center of the blade is frozen to the drive shaft. So far, I've tried some Blaster penetrating oil, dwell time (up to three days so far) and firm but not excessive wiggling combined with steady downward 9-3 position pulling as I rotated my hold on the blades (the fan motor and bracket are still secured to the top of the vent). I know I can remove the entire fan and motor, but I was hoping to remove the blade from the motor as I was able to with the other one.
I called FV and they said I should forget removing it, they know longer even recommend it, and said I should just clean it the best I can. If I have to I will
, but I thought I'd post here first and see if anyone else has run into this problem and over come it.
