Damper gets stuck closed
How can I fix the damper so it will open when the fan is turned on. This unit is 5 years old and runs very well. However, this week I noticed the damper won't open. I have to open the window and pull it open.
The damper on my fan would stick to the weather seal also. Try this. This isn`t easy, but I held open the damper, and I applied caranuba car wax to the damper and rubber seal it touches when closed. It has worked great. Spaying silicne on it did not work as well.

508 duct vent into Attic?
We purchased the 508 direct vent over a years ago for another applicaiton that we chose not to move forward with. Today, we are rennovating our 3rd floor apartment and would like to use this vent with duct connection to an attic vent. Is this possible?
I live it Marietta,Ga mine is vented in and unfished attic which is ok according to our local building codes. I suggest you check with your local building inspector or code inforcement dept.

Can I replace a Broan 509A with a 509S while retaining the exterior vents?
My condo installed with a Braun 509A (yes, A, see image!) when it was renovated many years ago (could be 30+ years). The fan has served us well but everything has a lifespan and it is desperately in need of upgrading and replacing. I planned on buying the 509S to replace it as it's the same size and model family.
The challenge I have is that accessing the fan from the outside is very difficult (we're on a high floor). I wondered if the 509S could be installed in place of the old fan from the inside retaining the existing venting to the outside from the old fan?
Thank you for your question on the model 509A through the wall exhaust fan. It does appear that you can use the exterior housing of the 509A with the new 509S. Please contact the Technical Service Department at 800-637-1453 for verification.
