I'm trying to replace a fan in my bathroom.The old one is a NuTone 668RP. I've managed to get all of the innards out of the old fan but can't figure out how the housing is attached. I don't see any screws or anything and it seems to be attached from the top. It's a downstairs bathroom so I can't get to the attic.

There's a stud on the "bottom" side (in the photo) but the side is not attached to the stud. I stuck my screwdriver up there and ran it along all four sides. Must be attached to the top somehow.

  • What make and model is the fan? Probably it was installed before the sheetrock was. – wallyk Oct 2 '16 at 20:56
  • @wallyk Thanks. I've added the photo. It just wasn't an option in the mobile site. Let me see if I can find the make and model. – Patrick McElhaney Oct 2 '16 at 20:58
  • Flanges outside the box attached to studs? – bib Oct 2 '16 at 21:01
  • No. As you can see I stuck a screwdriver up all sides and bent it in a bit. As far as I can tell it's attached from the top. – Patrick McElhaney Oct 2 '16 at 21:05

Okay, I found the same model on Amazon so I'm just going to replace the motor, fan, and light.
