BROAN-NuTone S99080592 Motor

The BROAN-NuTone S99080592 Motor is a high-performance, 120V ventilation solution engineered for precise fitment in multi-function ceiling units. Operating at 0.9 Amps with a maximum speed of 3000 RPM, this CCW rotation motor provides the torque necessary to maintain optimal CFM ratings in domestic exhaust systems. This specific induction motor features a 1-inch stack, a 2-prong plug, and two mounting studs on the rear for a secure, vibration-resistant installation. Built for durability in high-moisture environments, it is the primary drive unit for the fan assembly in several legacy and modern Broan-NuTone vent fan configurations, including heater/fan/light combination units.

As a veteran-grade OEM replacement motor, the S99080592 ensures electrical compatibility without the need for field modifications or wiring jumpers. The 7/32-inch diameter shaft includes a flat side to ensure a keyed, non-slip fit for the blower wheel. For contractors, this part offers an exact mechanical match for the 99080592, restoring system efficiency and reducing sones caused by worn bearings or imbalanced armatures in aging bathroom ventilation systems.

Common Questions

Is this the correct replacement for a squeaking bathroom fan?
Yes, if your model matches the 9905 or 665 series, a squeaking or grinding noise typically indicates worn motor bushings. Replacing the motor with the S99080592 restores quiet operation.

Does this motor include the fan blade or blower wheel?
This is the motor unit only. You will need to transfer your existing blower wheel to the new 7/32" keyed shaft or purchase a compatible wheel separately.

How do I verify rotation before installation?
This motor is CCW (Counter-Clockwise) when viewed from the shaft end. Always verify your existing fan's rotation requirement to ensure proper airflow direction.
