okay---sounds like what you have is a Broan(brand) bathroom exhaust fan. but yeah---to COMPLETELY rebuild, refurbish & restore a Broan, you can buy the kit to do so, online. That way---you don't needta do a buncha work, installing a new one--rewiring, cutting, drilling, crawling upstairs, etc. You just plug-n-play the new fan motor, heating element & light bezel inta the existing fixture. yup. Given that the original install was about 20 years old, being able to obtain this kit was a time & labor saving. Yup. I boxed up the old parts(some of which were still usable) in the new box, and stored it in the attic. Yeah, I know that goes against the current trend of dumpstering everything, but oh well. Thankk Mee.
