Lennox 72L05 Motor

The Lennox 72L05 Motor is a high-performance 1/10 HP condenser fan motor designed for precise thermal regulation in Lennox outdoor units and compatible HVAC systems. Engineered for 208/230V single-phase operation at 1075 RPM, this 42 frame motor ensures consistent airflow across the condenser coils to maintain optimal heat exchange. This direct drive motor features a durable sleeve bearing design and a 1/2-inch by 2-inch shaft, making it a drop-in OEM replacement part for technicians servicing residential and commercial air conditioning equipment. Built for continuous air-over duty, the 72L05 provides the reliability required in demanding environments, with a CWLE rotation and a requirement for a 5 MFD @ 370 VAC capacitor. Whether you are replacing a failed condenser motor or performing preventative maintenance, this 72L05 motor offers the mechanical integrity needed to restore system efficiency and prevent compressor overheating.

• Optimized Performance: Specifically tuned for 1075 RPM to provide the exact CFM required for matched Lennox condenser coils.
• Easy Installation: Features a standard 42 frame size and 1/2" diameter shaft for seamless mounting in existing bracketry.
• Industrial Grade Construction: Built with thermal protection and a single-speed, 1/10 HP design to withstand peak summer cooling loads.
• Broad Compatibility: Directly replaces part numbers 72L0501 and 20390801 across Lennox, Armstrong, and Ducane brands.

What capacitor is required for the Lennox 72L05?
This motor requires a 5 MFD 370 VAC run capacitor (not included) for proper startup torque and efficiency.

Can I use this as a replacement for a 1/8 HP motor?
Technicians should verify the amp draw and RPM; however, the 72L05 is specifically rated at 1/10 HP. Using a lower horsepower motor than the original specification can lead to premature failure.

What is the rotation direction?
This model is configured for Clockwise Lead End (CWLE) rotation. Always verify the fan blade pitch before finalizing the installation.
