Lennox 36K20 Blower Motor

The Lennox 36K20 Blower Motor is a heavy-duty, 3-speed direct drive blower motor engineered for consistent airflow in residential furnaces and air handlers. This 1/2 HP blower motor operates on a standard 115V single-phase power supply at 1075 RPM, drawing 9.0 Amps under full load. As a PSC (Permanent Split Capacitor) motor, it requires a 7.5 MFD 370V capacitor for optimal torque and energy efficiency. Built on a modular NEMA 48 frame with a 5.6-inch diameter, this unit features a 1/2-inch x 3-inch shaft and uses sleeve bearings for quiet, vibration-isolated operation. Designed for CCWLE rotation (Counter-Clockwise Lead End), it integrates seamlessly with belly band mounting systems common in Lennox and GCK075 series units. Replacing a failing OEM Lennox 36K20 prevents heat exchanger overheating and ensures your system maintains the static pressure required for effective climate control.

• Multi-Speed Versatility: Features 3-speed taps allowing precise airflow adjustment to match system CFM requirements.
• Direct Fit Compatibility: Replaces Emerson 47463-001 and K55HXKRK-9751, ensuring minimal downtime during field installation.
• Optimized Performance: The 1075 RPM motor speed provides the necessary velocity for standard ductwork without excessive noise.
• Durable Construction: Engineered with a sleeve bearing system and Class B insulation for reliable service in high-cycle HVAC environments.

What are the signs that my Lennox 36K20 motor is failing?
Technicians typically look for restricted airflow, "hunting" between speeds, or a humming sound indicating a bad HVAC capacitor or seized bearings.

Does this motor include the capacitor?
The 7.5 MFD 370V capacitor is essential for the PSC motor circuit and should be replaced alongside the motor to ensure proper starting torque.

Is the 36K20 motor reversible?
This specific model is typically configured for CCW lead end rotation; verify your fan wheel orientation and lead end rotation before securing the belly band clamp.
