That fan is really filthy

Just happened to notice just how filthy the fan blades were getting so it was time to get them cleaned up.
Looking at how to do this, I knew it would have to be from the inside, as getting on top of the curved Alto roof is probably not the best way to go about it. To get at the blades, you need to remove the screen, which at first attempt was quite resistant A little internet research showed me just where to pry to pop it off, and sure enough, no problem. To remove the blades, first remove the screw that holds on the knob to open the cover, then remove the 4 screws that attach the inner panel. Next, I used an allen key to loosen the spindle nut and allow the fan to slide off.

Being able to reach outside now, I cleaned the motor and mounts as well as the inside of the cover. Put it all back together and it was as good as new.


  1. Jim, when you were doing this, did you notice any way to oil the fan bearings or is everything sealed?

    1. Everything is pretty sealed, but anything that moved got a squirt of WD, like the shaft, the cover hinge, etc. The other thing to keep an eye on is the little on/off interlock switch for the cover. It seems to stick down a lot. This is accessed from the roof, with the cover wide open.
