Shower/bathroom exhaust fan

I noticed the glued on foam insulation had come loose and was tangled in the fan and prevented the fan from working. Removed the roof cover to free the fan so all is well....just need to replace the foam strip, is there any better material to use that will stick better in an area that can be, humid, hot, dry, frigid, etc. BTW, checked the bathroom fan and that strip was also unglued just not tangled in the fan..

Thanks

Well campers are made for the outdoors whether you be in the cold or in the hot and humid Heat these seals are good for just about any use. One seal over the next doesn't make a difference

I had the same issue. Tried replacing with a thicker, tube style weatherstripping, but I found that the vent was harder to close and "seat" properly. So I replaced with similar type foam weatherstripping. I figure I may have to do that every two years, given how long the original lasted...

Better Idea

Ditch the foam seal altogether and get a roll of this:
https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1
Install it on the metal rim of the vent instead of the lid. I did this about three years ago, no leaks and no problems.
I also use this on the bottoms of the propane tanks to protect the sharp bottoms from rust and digging into the the dual propane bottle rack.
I had one roll for over ten years and the self adhesive inside the trim was still good, I use it anywhere I have a sharp edge that needs protecting.

I'm having the same issue with both of my exhaust fans. the shower fan got tangled and stopped rotating. I tried to take the fan apart from the inside and was able to get most of the weatherstripping removed.
What is the best way to access that area? From the inside or outside? If outside is there some resealing required? Thanks

The fan lid/cover can be removed from the outside by removing 3 screws that have rubber type washers, there is no sealant to replace. The lid is attached to the fan itself and not the roof. Once the lid is removed you can easily clear of debris and wipe out the dirt before reinstalling a foam or some other type of seal and then the 3 screws.

Im not sure I explained that very well, when you get on the roof and remove the 3 screws from the lid it will make sense.

Pop up Ventline Fan foam seal

Same thing happened in our 2017 23D. Removed exterior cover and took out cheapy foam seal. Put lid back on and left it that way. Did both fans and never had a problem with water coming in when pulled down in the closed position. When we got our 2019 FC 25 home that was one of the first things I took care of. Removed the same cheapy foam seal and put the lid back on. When we close the fan for travel it pulls close real nice. There is a substantial overlap when you pull that lid down. I have sprayed the roof with a hose when washing and waxing and have had no water coming in those Ventline Fans. Sooo...I do not see any reason to try and stick some other kind of self stick rubber seal in there. Works for us. Your results may be different. Happy travels.

Vent line shower fan gasket turned to dust on my 2015 FB30. Pulled and replaced with sponge tape. Whilst at it I pulled the bathroom fan and it had no gasket at all and never did. Put one on there as well. Now the little water drops on floor in front of toilet after towing in rain will likely be gone. Click image for larger version

Thank you guys... this just happened to us our last trip. I was able to take screen out and remove the tangled gasket. Now I know to use simple foam insulation to repair.

Another round of thanks from BC. Easiest fix in a long time.

Smile Using 1x1 foam in Ventline fan

I noticed sealing foam on the Ventline fan for the shower was exposed when the vent was closed. Investigating I found the installed 3/8 by 3/8 cheap foam to be completely inadequate for providing a seal when the vent is closed. I am disappointed that Airstream even delivered my trailer with such a lousy implementation.
Looking at the vent there is an outer channel surrounding the fan. It is pretty obvious that sealing foam with 1x1 cross section can fit in the channel. I purchased some 1x1 foam and installed it (https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1 ) . It seems to fit perfectly with about 1/8 extending upward out of the ring, which allows the cap/cover to seat nicely on the foam and fully close. The foam compresses easily. It took only a few minutes to remove the cover and insert the 1x1 foam. I am happy with the result.
