Broan S90 and S90-A: Round Ceiling Bath Fan Motor Assembly Service
The Broan S90 uses a compact round housing with a motor assembly that mounts directly to the housing ceiling. The S90-A is the replacement motor assembly for this housing, sold as a complete motor and blower wheel unit. A motor producing grinding or squealing noise has a worn bearing and should be replaced before the shaft seizes. NuTone and Broan are sister brands, so an S90 labeled under either brand uses the same motor assembly.
Most Replaced Parts on the Broan S90
Motor Assembly for the Broan S90
The S90-A motor assembly replaces the complete motor and blower wheel inside the S90 housing. A motor with a worn bearing produces grinding or squealing noise and should be replaced promptly. The assembly slides out after the grille is removed and the motor plug is disconnected.
Blower Wheel for the S90
The blower wheel generates exhaust ventilation airflow. Lint and dust accumulate on the blades over time, reducing airflow capacity. Clean the blower wheel annually with a vacuum and soft brush.
Grille for the Broan S90
The round grille mounts with spring clips. A yellowed, cracked, or damaged grille can be replaced without removing the motor assembly.
Housing and Duct Connection
A housing that has pulled loose from the exhaust duct allows exhaust air to discharge into the attic rather than to the exterior.
