Lennox 25J36 Motor

The Lennox 25J36 motor is a direct-drive condenser fan motor designed for high-performance heat pump and air conditioning applications. Operating at 208/230V, 1-phase, this 1/3 HP motor delivers a consistent 1075 RPM, ensuring optimal airflow across the outdoor coil to maintain critical head pressures. Built with a NEMA 48 frame and a 1/2-inch diameter shaft, it serves as a precise OEM replacement motor for various Lennox Elite and Signature series units. The permanently lubricated ball bearings and high-dielectric insulation are engineered for high-ambient environments, preventing premature winding failure. When replacing this unit, verify the microfarad rating of your run capacitor to ensure the start-up torque meets factory specifications. This HVAC replacement part is essential for restoring system efficiency and maintaining the factory-designed CFM output in residential and light commercial split systems.

• OEM Compatibility: Exact drop-in replacement for Lennox part number 25J36 and 25J3601, maintaining electrical integrity.
• Thermal Protection: Internal automatic reset thermal overload protection prevents motor burnout during high-static conditions.
• Efficient Performance: The Permanent Split Capacitor (PSC) design offers a balance of high torque and energy efficiency.
• Environmental Resilience: Features a totally enclosed air over (TEAO) enclosure to protect internal components from debris and moisture.

Common Questions

What capacitor does the Lennox 25J36 require?
This 1/3 HP motor typically requires a 5 MFD or 7.5 MFD / 370V run capacitor; always check the nameplate on the specific Lennox 25J36 unit for the confirmed rating before installation.

Can I use this motor to replace a different RPM rating?
No. You must match the 1075 RPM specification exactly to avoid over-amping the motor or causing refrigeration cycle imbalances due to incorrect airflow.

Is the rotation reversible on this condenser motor?
The Lennox 25J36 is typically keyed for specific rotation, but many Emerson/US Motors equivalents offer reversible rotation by swapping the internal lead connectors during the install.
