663LNB vs. 663LN
I have a Nutone 663LNB with a dying motor. Will the replacement motor for the 663LN (Nutone Fan Motor # 65878) work in its place?
Thank you for your question on the model 663LNB exhaust fan/light. The 65878000 would be the replacement motor for the 663LNB. You can get this motor through the “Shop for Parts” link at the top of our web site page.

Which direction does the impeller install?
I would assume that the flat part with the holes is on the upstream side and the blades on the downstream side, but want to be sure.
The impeller wheel should be attached so that the blades are towards the motor. If you have further questions, please feel free to contact our Technical support group at 800-637-1453.
