Lennox 12L11 Motor
The Lennox 12L11 Motor is a heavy-duty, 3-speed PSC blower motor specifically engineered for high-static residential furnace and air handler applications. Operating at 208-230V and managing a 1/3 HP load, this 1075 RPM direct-drive motor ensures consistent static pressure performance across your heat exchanger and evaporator coils. As a veteran-grade OEM replacement motor, it features a standard 48-frame diameter and is built to handle the cycling demands of modern Lennox HVAC systems. When replacing a furnace blower motor, technicians should verify the 5 MFD at 370V capacitor requirements and ensure the motor rotation matches the blower wheel pitch to maintain design airflow. This HVAC replacement part is optimized for precise speed-tapping via the control board, allowing for field-adjustable CFM settings to meet specific temperature rise requirements during the cooling or heating seasons.
Key Benefits:
- 3-Speed Versatility: Direct-drive multi-tap leads allow for precise airflow tuning based on system static pressure.
- NEMA 48 Frame: Standardized housing size ensures compatibility with most Lennox furnace blower decks and belly-band mounts.
- High-Efficiency PSC Design: Permanent Split Capacitor operation provides reliable 1/3 HP output with lower amp draw.
- Broad Compatibility: Engineered as a direct drop-in for Lennox 12L11 and various OEM cross-references.
- 1075 RPM Performance: Optimized for standard direct-drive blower wheels to ensure quiet operation and balanced air delivery.
Common Questions:
What is the frame size and shaft dimension for the Lennox 12L11?
The motor utilizes a standard NEMA 48 frame with a 1/2-inch diameter shaft, typical for residential Lennox furnace motor assemblies.
Does this motor require a run capacitor?
Yes, as a PSC blower motor, it requires a 5 MFD / 370V run capacitor (sold separately) to maintain proper torque and thermal protection.
How do I identify the speed taps for installation?
Technicians should refer to the wiring diagram on the motor shell; typically, the black, blue, and red leads correspond to high, medium, and low speeds for 2-stage or multi-speed configurations.
