Lennox 32904 Motor
The Lennox 32904 Motor is a heavy-duty 115V 1/2HP blower motor designed for high-static pressure applications in residential and light commercial HVAC units. Operating at 1075 RPM, this 3-speed permanent split capacitor (PSC) motor allows for precise airflow adjustment to meet specific cooling and heating requirements. Built with a NEMA 48 frame and all-angle sleeve bearings, it provides reliable performance and vibration dampening in various mounting configurations. This direct drive blower motor features a 5-inch shaft length with a 1/2-inch diameter, ensuring compatibility with standard blower wheels and Lennox replacement parts. Utilizing Class B insulation for thermal protection, it is engineered to handle the demands of continuous cycling while maintaining electrical efficiency. Whether you are performing a furnace motor replacement or upgrading an air handler, the 32904 provides the torque and multi-speed versatility needed to restore system CFM to OEM specifications.
- Broad Compatibility: Direct-fit replacement for numerous Lennox and Armstrong furnace models, reducing field modification time.
- Multi-Speed Versatility: Triple speed taps for tailored airflow control across different seasonal modes.
- Enhanced Durability: Thermal overload protection prevents winding burnout during high-load conditions or voltage fluctuations.
- Quiet Operation: Precision-balanced rotor and sleeve bearing design minimize mechanical noise and resonance within the ductwork.
Common Questions
What capacitor is required for the Lennox 32904?
This motor typically requires a 7.5 MFD / 370V run capacitor; always verify the rating on the specific motor nameplate before installation.
Can I use this to replace a single-speed motor?
Yes, provided the frame size, voltage, and horsepower match, though you will only utilize one of the three speed taps for your primary application.
Does this motor include the mounting bracket?
This is the motor only; it is designed to fit into standard torsion flex mounts or belly band brackets common in Lennox air handlers.
