Lennox 27H45 Motor

Upgrade or restore your HVAC system with the Lennox 27H45, a high-performance 1/6 HP condenser fan motor engineered for precision and reliability. Operating on 208-230V single-phase power at a consistent 1075 RPM, this PSC motor (Permanent Split Capacitor) is the direct OEM replacement for Lennox 27H4501. Designed with a 48-frame assembly and a 1/2-inch diameter shaft, it provides the exact mechanical fit required for Lennox, Armstrong, and Ducane outdoor units. Technical specifications highlight a 1.1 Amp draw and CCWLE rotation (Counter-Clockwise Lead End), ensuring optimal airflow through the condenser coil. For peak performance and to prevent premature winding failure, pair this motor with a new 5 MFD 370 VAC capacitor. Built with a durable sleeve bearing system and thermal protection, this motor maintains system efficiency and original sound levels in demanding residential and light commercial environments.

• Direct OEM Compatibility: Seamlessly replaces Lennox 27H4501 and related Allied Air components without field modifications.
• High-Efficiency Performance: The 1075 RPM 1/6 HP design ensures proper heat exchange across the condenser, maintaining SEER ratings.
• Rugged Construction: Features thermally protected windings and a 48-frame housing for continuous air-over duty in extreme temperatures.
• Standardized Installation: Utilizes a standard 208-230V 1Ph configuration for straightforward wiring to existing contactors and defrost boards.

What capacitor is required for the Lennox 27H45 motor?
This motor requires a 5 MFD @ 370 VAC run capacitor. Using an out-of-tolerance capacitor can lead to overheating and potential motor failure.

Is the 27H4501 the same as the 27H45?
Yes, the 27H45 is electrically and mechanically identical to the 27H4501 and can be used as a direct drop-in replacement.

What is the rotation direction for this replacement?
The rotational direction is Counter-Clockwise Lead End (CCWLE), which is critical for proper fan blade orientation and airflow direction.
