Re: Bathroom Fan - When to replace?
I agree with Raven, check into replacing the motor first before swapping out the housing and related ducting. I've done this many times with older units that would have been a real pain to replace. Motors are easy and plentiful.
If you don't get anywhere with the manufacturer in getting a new motor, look in the phone book for local companies that specialize in electric motor repair. That is where I got the replacement motors for my applications. They will need your current motor to cross reference a replacement.
