Gasket on exhaust fan

[chipr]

The gaskets on both of our exhaust fans (WC and shower) have been failing. Initially, it sounded like a piece of thin plastic film was hitting the fan blade and now it seems a foam gasket has failed. (See attached image).

I took off the bottom cover but that does not provide access. Does anyone have experience with this kind of failure? What kind of repair is it? Is it a simple gasket replacement or something more? Easy to access and replace? Will I have to reseal the unit from the roof?

Many thanks!

If I remember correctly, there are screws on the pull handle, going through a hole in the metal strip into the handle. Take those off, remove the handle, get on a ladder outside the trailer and pull the vent cover off. Replace the old 1/4" weather stripping with some new stuff from Home Depot and reassemble. At least that's what I did.

I replaced the exhaust fan gaskets on my 2015 27’ from the roof. Three screws hold the fan cover in place. I believe the original gaskets are not form fitting to the cover, rather a straight strip. I used some 1/4” foam weather stripping from HD.

Mine came off and I just trashed it and did not replace. The fan cover has a lip that extends down over the fan body so it will not leak and it’s never going to be air tight anyway. Been that way for 3 years without a problem.
