Lennox 68J24 Motor

The Lennox 68J24 (Model 68J2401) is a high-performance direct drive condenser fan motor designed for direct compatibility with Lennox HVAC systems, serving as the factory-authorized update for the legacy 100483-29 part number. This 1/3 HP condenser motor operates at 1075 RPM on a 208-230V single-phase circuit, pulling approximately 2.1 Amps. As a Permanent Split Capacitor (PSC) motor, it requires a 5 MFD / 370V capacitor for proper phase shift and torque. Built with a NEMA 48 frame, it features a 1/2-inch diameter shaft extending 2.75 inches, rotating in a CCWLE (Counter-Clockwise Lead End) direction. Manufactured by Nidec Motors for Lennox, this unit utilizes durable sleeve bearings and an open air-over (OAO) enclosure to ensure optimal thermal management during high-ambient summer operation. For contractors, this OEM component ensures the lead length and mounting bolt patterns match the original air conditioner specifications exactly.

Technical Key Benefits:

• Direct OEM Replacement: Replaces Lennox 68J24 and 100483-29 without the need for mounting bracket modifications or shaft cutting.
• Optimized Efficiency: The PSC motor design provides consistent 1075 RPM 1-speed operation to maintain factory-spec CFM across the condenser coil.
• Rugged Construction: Built by Nidec with a heavy-duty 48 Frame and all-angle sleeve bearings for quiet, vertical-shaft-up or shaft-down installations.
• Standardized Specs: Features a 0.5-inch flat shaft and standard 208/240V wiring for fast integration into existing residential and light commercial condensing units.

Common Technical Questions:

What capacitor is required for the Lennox 68J24 motor?
This 1/3 HP motor typically requires a 5 MFD / 370V run capacitor. Always check the motor nameplate during installation as capacitor requirements may vary by production batch.

Is this motor reversible?
No, this specific model is a CCWLE (Counter-Clockwise Lead End) rotation motor. Verify the fan blade pitch matches this rotation before installing.

Can I use this to replace a 100483-29 motor?
Yes, the 68J24 is the official updated part number and direct technical substitute for the 100483-29 model.
