Lennox 12Y65 Motor

The Lennox 12Y65 is a high-torque condenser fan motor engineered for continuous-duty operation in residential and light commercial condensing units. This 1/4 HP HVAC motor operates at 1.7 amps and features a 825 RPM rating to maintain specific airflow static pressure requirements. Designed as a NEMA 48Y frame motor, it utilizes a permanent split capacitor (PSC) design requiring a 10 MFD at 370V capacitor for proper phase displacement and starting torque. The assembly includes a 1/2-inch diameter flat shaft with a length of 1.5 inches, ensuring compatibility with standard fan blade hubs. Reliability is supported by full ball bearing construction for reduced friction and a CCWLE rotation (counter-clockwise from lead end). This OEM Lennox replacement motor effectively restores system efficiency by providing precise thermal dissipation under varying load conditions, making it an essential component for technicians maintaining high-efficiency Lennox and Allied air conditioning systems.

• Direct OEM Compatibility: Engineered as an exact drop-in for Lennox 100483-43 and Allied 49W86, eliminating field modifications.
• Enhanced Durability: Features ball bearings and Class B insulation for superior heat resistance in outdoor environments.
• Efficient Performance: Optimized 825 RPM speed profile reduces noise levels while maintaining critical head pressure control.
• Thermal Protection: Includes integrated automatic reset overload protection to prevent stator winding failure during voltage fluctuations.

What capacitor does the Lennox 12Y65 require?
This motor requires a 10 MFD / 370 VAC capacitor for proper operation. Using an old or incorrectly rated capacitor can lead to overheating and winding failure.

Can this motor be used for 208V and 230V systems?
Yes, the Lennox 12Y65 is rated for 208-230V single-phase power supplies, making it compatible with the majority of residential split systems.

Is the rotation reversible on this model?
No, this motor is fixed for counter-clockwise rotation from the lead end (CCWLE). Verify your existing fan blade pitch before installation to ensure correct airflow direction.
