MaxxFan Roof Top Vent Will Not Fully Close

[dewdev]

In an effort to clean the MaxxFan, I got up on the roof and remove the exterior screeing and disconnected the linkage so I could fully open the vent for topside cleaning.

After putting everything back together, I ran the fan and the vent opened without any problem but when shutting the fan off the vent would only partially close. I had to get on the roof to push the vent fully closed. When pushing the vent closed, it had a slight hitch in the vent but then fully close. I tried operating the fan a second time and the vent opened with no problem but closing the vent only slightly closed. Closing by hand is not an option while camping as I do not take a ladder with me. Any suggestions would be greatly appreciated.

Thanks Richard

Did you reposition the spring arm that connects to the cover?  I recently rebuilt my fan when the gear housing self destructed.  In order for the cover to open and close correctly the gear must be aligned correctly.  If you merely disconnected the linkage then the gears should not have been affected.  The spring arm needs to be connected to the support frame that raises and closes the cover.

Here’s a pic with the arm attached to the frame that the cover attaches too after I put the new gear assembly in.

 

This is the spring arm of my destroyed gear assembly.

 

 

Here I’m holding the spring arm off the cover support.

Mike:

I have 2 arms that connect to the cover. (2018 Elite II) Both were reconnected to the cover. Is this what you are referring to?

The spring arm Mike is referring to is highlighted in the picture.

There is a spring arm that attaches to one of the arms, see the photo above that Mike highlighted.  If you did not remove the arms from the gear assembly it should close correctly.  If you removed the arms (that are connect by the hex shaft) from the gear assembly and didn’t reinstall it exactly in the same position that was in when removed that could be the problem.
