Lennox 12Y75 Motor

The Lennox 12Y75 Condenser Fan Motor is a heavy-duty, single-phase OEM replacement designed for high-demand residential and light commercial condensing units. Operating at 208-230V and 1075 RPM, this 1/5 HP motor provides the necessary torque for consistent airflow and thermal regulation in AC and heat pump applications. Built to strict Lennox HVAC 12Y75 standards, this unit serves as the direct replacement for Lennox 43W49, ensuring a drop-in fit without the need for mounting modifications or bracket adjustments.

This 42Y frame motor features a CCWLE rotation (Counter-Clockwise Lead End) and is engineered for permanent split capacitor (PSC) operation. When replacing the Lennox 12Y75 motor, technicians should note the 1.1 - 1.2 FLA rating and the requirement for a 5 MFD / 370V capacitor to maximize efficiency and protect the windings from premature failure. This OEM condenser fan motor is the standard service solution for maintaining factory-specified performance in Lennox, Armstrong, and Ducane outdoor sections.

• Direct OEM compatibility: Replaces 43W49, 100483-21, 10F79, and 100483-44, maintaining original equipment integrity.
• Optimized Performance: Specifically tuned for 1075 RPM operation to meet factory airflow requirements in 208-230V 1PH systems.
• Contractor-Grade Durability: Engineered for outdoor environments with a rugged 42Y frame to withstand high ambient temperatures and continuous duty cycles.

Is the 12Y75 a suitable substitute for a 1/6 HP motor?
Yes, this motor is rated for 1/6-1/5 HP applications, providing sufficient power for units originally equipped with lower-fractional motors while maintaining a 1075 RPM operating speed.

Does this motor include the run capacitor?
No, the capacitor is sold separately. It is a best practice for technicians to install a new 5 MFD / 370V capacitor whenever a new condenser fan motor is installed to ensure proper starting torque.

What is the direction of rotation?
The 12Y75 is configured for CCWLE (Counter-Clockwise Lead End) rotation. Always verify the fan blade pitch matches the rotation before completing the installation.
