Lennox 13H36 Motor

The Lennox 13H36 Motor is a high-performance direct drive condenser fan motor designed for critical cooling applications in residential and light commercial units. Operating at a nominal 1/4 HP and 825 RPM, this PSC motor provides the high-torque start and efficient continuous-run performance required to maintain head pressure in Lennox HVAC systems. This unit is electronically and physically identical to part 13H3601, ensuring a drop-in replacement for technicians servicing legacy or modern heat pumps and air conditioning condensers. Built with a 48-frame diameter and engineered for 208-230V single-phase power, it features a counter-clockwise lead end (CCWLE) rotation. For maximum performance and to prevent premature failure, it is professionally recommended to match this 1/4HP 1Ph 825RPM motor with a 7 MFD 370V capacitor. Its thermally protected design and rugged construction allow it to thrive in high-ambient outdoor environments where standard motors typically fail.

Key Benefits

• Direct OEM Compatibility: Verified as the exact replacement for Lennox 13H3601, eliminating mounting and wiring guesswork for field contractors.
• Optimized Airflow: The low-speed 825 RPM design is specifically tuned for large-blade condenser fans to reduce decibel levels while maximizing heat dissipation.
• Industrial-Grade Build: Features a resilient 5.6-inch diameter 48Y frame and robust bearings designed for the continuous air over (CAO) duty cycles common in summer peak loads.
• Standardized Integration: Uses common 208-230V wiring configurations with single-phase power, compatible with a wide range of Allied, Armstrong, and Ducane systems.

Common Questions

Is the 13H36 compatible with a 3-speed fan setup?
No, this is a single-speed 825 RPM motor designed specifically for condenser fan applications where constant airflow is required to regulate refrigerant temperatures.

What capacitor does the 13H36 require?
Technical specifications for this 1/4 HP motor designate a 7 MFD / 370 VAC run capacitor. Verification of the existing capacitor's microfarad rating is essential during any motor swap.

Does this motor include the fan blade?
This part number refers to the motor only. When installing, ensure the existing fan blade is balanced and free of debris to prevent shaft vibration and bearing wear.
