S97020971 Broan-NuTone Blower Assembly for Exhaust Fans, Fixes Dead Fan, Weak Airflow or Loud Noise

S97020971 is a genuine Broan-NuTone bathroom exhaust-fan motor and blower kit. It replaces discontinued motor assembly S99080582. The kit includes a preassembled motor, blower wheel and mounting plate for select 90, 100 and 110 CFM Broan-NuTone ventilation fans.

A worn, seized or electrically failed motor assembly may contribute to a fan that does not run, produces weak airflow, hums, rattles, grinds or operates intermittently. Similar symptoms can also result from dust buildup, a blocked or disconnected duct, a stuck exterior damper, loose mounting hardware, damaged wiring or a faulty wall control.

Before ordering, confirm the complete fan model shown on the label inside the housing. Similar Broan-NuTone fan housings may use different motor plates, connectors and blower wheels. Disconnect electrical power before removing the grille or blower assembly. Clean the housing and duct opening before installing the replacement.

Is This the Right Part?

Confirm the complete model number before ordering. Similar Broan-NuTone fan housings may use different motor plates, connectors, blower wheel sizes and mounting points.

Common Symptoms

• Fan does not run at all when switched on
• Fan runs but produces weak or reduced airflow
• Loud grinding, squealing or rattling noise during operation
• Motor hums but blower wheel does not spin
• Fan runs intermittently or shuts off unexpectedly
• Excessive vibration during operation
• Motor overheats and trips thermal protection cutoff

Check Before Replacing

• Inspect and clean the fan grille, blower wheel and housing interior — heavy dust accumulation restricts airflow and causes overheating without motor failure
• Confirm the duct connection is intact and the exterior vent cap and damper open freely — a blocked or stuck damper produces weak airflow even with a functional motor
• Verify the fan is receiving correct voltage at the switch and that wiring connections inside the housing are secure
• Confirm the blower wheel turns freely by hand before condemning the motor — a seized wheel can stall a functional motor
• Match the complete fan model number on the housing label to the verified compatibility list before ordering

Installation Notes

1. Disconnect electrical power at the breaker before removing the grille or accessing the blower assembly.
2. Photograph the wiring connector and mounting plate position before disconnecting anything.
3. Remove the fan grille, unplug the motor connector, and unscrew the mounting plate from the housing.
4. Compare the new assembly against the original — confirm motor plate dimensions, connector type and blower wheel size match before installing.
5. Slide in the new S97020971, secure the mounting plate, reconnect the wiring, reinstall the grille, restore power and test operation.

Use a qualified technician when diagnosis or installation is outside your experience.
