Replace the motor of a worn out fan with the Broan-NuTone genuine C350BNR replacement motor assembly. This is only compatible with the old NuTone model 696N with a housing size of 8 x 7-1/4 in (manufactured prior to the year 1999). It does not work with the 696N-R01, 696N-R02 and 696N-R03 fans with 7-1/4 x 7-1/2 in housings. This replacement motor assembly takes 10 min or less to install, easily snaps into your existing housing, does not require any wiring.
