Lennox 72H73 Motor

The Lennox 72H73 is a high-performance condenser fan motor designed specifically for demanding outdoor HVAC applications. Built as a 48-frame motor, this authentic Lennox replacement part (also referenced as 72H7301) delivers 1/6 HP at 825 RPM, ensuring consistent heat exchange and airflow across the condenser coils. This PSC motor operates on 208/230V single-phase power at 60 Hz and features a counter-clockwise lead end (CCWLE) rotation, making it a direct fit for 10AC and HS23 series units.

Engineering details include a durable rolled steel frame and an aluminum flange for superior corrosion resistance in harsh environments. The motor utilizes a permanent split capacitor (PSC) design requiring a 5 MFD / 370 VAC capacitor (sold separately) for optimal torque and efficiency. With its 1/2-inch by 3-inch shaft and stud mounting, this 825 RPM condenser motor provides a reliable solution for restoring system performance and preventing high-pressure trips due to fan failure.

Key Benefits

• Direct OEM Fit: Drop-in replacement for 72H73 and 72H7301, eliminating mounting modifications.
• Thermal Protection: Integrated internal overload protection prevents winding damage during extreme ambient conditions.
• Corrosion Resistance: Rolled steel housing and aluminum components resist oxidation in outdoor settings.
• Quiet Operation: Precision-balanced internals reduce vibration and decibel levels during the cooling cycle.
• Broad Compatibility: Supports various Lennox, Armstrong, and Ducane outdoor condensing units.

Common Questions

What capacitor is required for the Lennox 72H73 motor?
This motor requires a 5 MFD 370 VAC capacitor. We recommend replacing the capacitor whenever installing a new motor to ensure long-term winding health and proper starting torque.

Can this motor replace a higher RPM condenser motor?
No. You must match the 825 RPM specification. Using a different speed will alter the airflow across the coil, potentially causing refrigerant pressure issues and compressor strain.

Is the rotation reversible on this unit?
No, this specific model is a Counter-Clockwise Lead End (CCWLE) motor. Always verify the rotation of your existing fan blade before purchasing to ensure proper airflow direction.
