Westinghouse 903075 4-speed Blower Motor 1/3 Hp 240V

Product Description

The WESTINGHOUSE 903075 is an OEM-style 4-speed blower motor rated at 1/3 HP and 240 volts, designed to drive the supply-air wheel in forced-air furnaces and air handlers. Running at 960 RPM, this multi-speed motor allows the air handler to operate across different airflow stages, supporting both heating and cooling modes in a single system. Licensed HVAC technicians and experienced service professionals handle installation and replacement of this component. Its multi-speed design makes it suitable for systems requiring variable airflow without a full variable-speed ECM drive.

This motor is used in residential and light-commercial forced-air applications where a belt-drive or direct-drive blower assembly requires replacement. It is suited for installations inside Nordyne furnaces and air handlers where a 240-volt, 4-speed blower motor is specified. When replacing a failed or degraded blower motor, verifying the HP rating, voltage, RPM, and shaft configuration against the existing unit is standard practice before ordering.

Key Features

• 4 selectable speed taps for flexible airflow configuration
• Rated at 1/3 HP for typical residential blower assemblies
• 240-volt operating voltage for compatibility with standard residential supply circuits
• 960 RPM operating speed for steady, consistent airflow delivery
• OEM-style replacement designed to match original motor specifications

Compatibility

Designed as an OEM-style replacement blower motor for select Nordyne furnaces and air handlers requiring a 240-volt, 4-speed, 1/3 HP motor at 960 RPM. Confirm shaft size, rotation direction, and mounting configuration against the original unit before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the unit before removing the existing motor or handling any wiring. Verify that the replacement motor shaft diameter, rotation direction, and mounting bracket match the original before completing the swap. Follow all applicable local codes and manufacturer wiring diagrams when reconnecting speed-tap leads.
