Fred,
I wonder if your fan actually experienced what mine is experiencing. The fan blade screws keep falling out where the bracket is attached to the motor.
When one screw is out and the other is loose, the blade droops. That may be how yours blade came too close to your slide fascia when the slides were closed.
I plan to add Loc-tite to all 8 of those screws
One other thing to watch. On about every other trip, check the bulbs for tightness if you have screw base bulb. In my previous trailer, my fan light used standard size screw base bulbs and one backed out and dropped on my kitchen island and shattered all over.
My fan light in this coach uses a small base screw in bulb. At a fuel stop I checked on the inside of the coach and found that one of the bulbs had fallen out and shattered on the top of my wood high-low table. Glass all over
I am not thinking of using a dab of glue from a hot glue gun at the edge of each bulb where it meets the top of the holder base.
BTW, please tell Lizzy the jam is awesome. Had it on an English muffin for dinner last night when I pulled into a CG in Albert Lea, MN. Ruby says thanks too. She helped me eat it
