Lennox 92W51 Motor

If you are servicing a residential or light commercial unit and the fan has seized or is pulling high amps, the Lennox 92W51 Condenser Fan Motor (Interlink Model 100483-33) is the required OEM replacement. This is a 1/6 HP, 208-230V, single-phase motor designed to run at 825 RPM. Built with ball bearings rather than sleeve bearings, it handles the vertical mounting and high-heat environment of a condenser cabinet with significantly better durability. As a PSC (Permanent Split Capacitor) motor, it requires a 5 MFD / 370V capacitor for proper startup and run torque. It features a CCWLE (Counter-Clockwise Lead End) rotation and is housed in a standard NEMA 48 frame with a 1/2-inch by 2.9-inch shaft. This motor is the factory-authorized swap for several older part numbers, including 63W25, 92W5101, 98M36, and 11X75, ensuring the fan blade pitch and CFM delivery remain within original system specs.

Key Benefits for Contractors:

• Direct OEM Fit: Eliminates the need for "make-it-fit" modifications or belly band adjustments in Lennox Elite, Merit, and Signature Series units.
• High-Efficiency PSC Design: Maintains factory energy ratings and prevents common overheating issues associated with generic motors.
• Ball Bearing Construction: Optimized for vertical stud mounting, providing longer service life in harsh outdoor conditions.
• Broad Cross-Reference: Replaces 63W25 and 92W5101, making it a versatile truck-stock item for Lennox service calls.

Common Questions:

Is this a multi-speed motor?
No, the Lennox 92W51 is a single-speed motor optimized specifically for 825 RPM condenser fan applications where constant airflow is critical for head pressure control.

Which way does this motor rotate?
This motor is rated for Counter-Clockwise Lead End (CCWLE) rotation. Always verify the fan blade pitch before installation to ensure proper airflow direction through the coil.

Should I replace the capacitor at the same time?
Yes. To ensure the 92W51 motor operates within its 1.0 Amp rating and to prevent premature winding failure, it is industry best practice to install a fresh 5 MFD / 370V capacitor during the motor swap.
