OEM Replacement Motor for Broan HVAC

This new OEM replacement motor is built for Broan HVAC controls and fits the 503-B unit. It restores original airflow performance when the factory motor fails. The part carries the Broan-NuTone brand for direct compatibility.

Direct-fit design simplifies installation

The motor matches the original mounting points and wiring so no adapters or harness changes are needed. Technicians can swap the unit without modifying the housing or control board. That reduces labour time on service calls.

Questions about this item

Does the S99080355 motor require periodic lubrication or brush replacement?

The OEM motor is a sealed unit designed for direct replacement without scheduled lubrication or brush service.

What thermal limit stops the motor first during continuous operation?

The internal thermal overload protector trips before the windings overheat, shutting the motor off until it cools.

How much noise and heat does the motor produce when running all day?

It operates at typical HVAC blower sound levels and the housing stays warm to the touch but within normal design limits.
