Replacing Fan Motor on Trailer Vent with MA10-20270

Updated 08/14/2019 | Published 08/13/2019

Question:

My fan has the tiny screw on the post to take the fan blades off. Is it a philips head screw or is it an Allen wrench?

I checked with the manufacturer and the tiny screw you're seeing is a set screw. You will use an Allen wrench/key to remove this. I'm attaching a picture with a set of installation instructions for you to refer to when you're replacing the MaxxFan Lift Motor # MA10-20270 . We don't have the new/updated instructions available, but where it refers to a nut holding the blades on to the motor shaft, this is now a set screw like you're seeing. All of the other steps will remain the same.
