If your bath fan is noisy or just doesn’t seem to move enough air, there’s an easy fix that doesn’t require any new wiring, venting or ceiling patching. Nutone’s No. 690NT Bath Fan Upgrade Kit ($30 to $40 at home centers or online) fits several models of Nutone, Broan and Nautilus fans. You’ll find the model number of your fan stamped on the metal plate that the fan motor is attached to. To see if your fan can be upgraded, go to nutone.com and type “690NT” into the search box. The Web page lists model numbers and shows photos of the compatible fans.
