Lennox 28M89 Motor

The Lennox 28M89 Blower Motor is a high-performance 1/3 HP HVAC replacement motor engineered for precision airflow in residential and light commercial air handlers and furnaces. Operating on 115V single-phase power at 1075 RPM, this 4-speed furnace motor (48 frame size) provides the versatility needed to tune system CFM for optimal static pressure and heat exchange efficiency. As a genuine OEM Lennox part, the 28M89 ensures a direct drop-in fit, featuring a 5.6-inch diameter and a 1/2" x 3" shaft to eliminate common mounting issues and vibrations associated with universal alternatives. This PSC blower motor is designed for CCWLE (Counter Clockwise Lead End) rotation and requires a 7.5 MFD 370 VAC capacitor for proper startup and run performance. Built with thermal protection and sleeve bearings, this motor is a reliable solution for maintaining indoor air quality and consistent climate control in compatible Lennox, Armstrong, and Ducane heating systems.

Common Questions

What capacitor is required for the Lennox 28M89 motor?
This motor requires a 7.5 MFD / 370 VAC run capacitor (sold separately) to ensure correct torque and amperage draw during operation.

Can this motor replace a single-speed or 3-speed blower motor?
Yes, the 4-speed capability allows for increased flexibility; however, you must ensure the 115V rating and 48 frame mounting match your specific blower housing.

What is the rotation direction of the 28M89?
The motor is designated as CCWLE (Counter Clockwise Lead End), which is common for standard residential furnace blower assemblies.
