Lennox 13H37 Motor

The Lennox 13H37 blower motor is a genuine OEM 1/3 HP replacement motor designed for high-performance air handling in specific Lennox residential and commercial units. Engineering for 208-230V single-phase operation at 1075 RPM, this 4-speed induction motor provides the torque necessary to maintain static pressure across various duct configurations. As a 48Y frame motor with a 1/2-inch x 3-inch shaft, it ensures a precise fit for older high-efficiency systems like the CHA16, CHP16, and GCS16 series. The CCW lead end rotation and 7 MFD 370 VAC capacitor requirement make it a drop-in solution for technicians looking to restore factory-spec airflow without modifying brackets.

Constructed with a rolled steel frame and aluminum flange, this Lennox 13H37 motor (also known as US Motors K55HXLCE-3608) is built to withstand the thermal stress of continuous air-over cooling. The 4-speed taps allow for granular control of CFM, ensuring the system can be tuned for both cooling and heating cycles. Whether you are performing a PSC motor replacement or a routine maintenance overhaul, utilizing this OEM Lennox HVAC motor guarantees electrical compatibility and physical mounting alignment, preventing the vibration issues often associated with generic multi-fit alternatives.

• Standard 48Y Frame: Ensures a direct mechanical fit into Lennox blower housing assemblies without mounting modifications.
• Multi-Speed Versatility: Features 4-speed taps to optimize HVAC airflow and system static pressure for specific tonnage requirements.
• OEM Electrical Specs: Matches the 2.1 Amp draw and 1075 RPM profile to maintain the original efficiency of the air handler.
• Industrial Construction: Utilizes self-aligning sleeve bearings and thermal protection to handle the rigors of continuous air-over (CAO) duty.

What capacitor is required for the Lennox 13H37?
This motor requires a 7.5 MFD / 370V run capacitor (sometimes cited as 7 MFD depending on exact production series) for proper startup torque and optimal running efficiency.

Can I use this to replace a 13H3701 part number?
Yes, the 13H37 is the direct engineering successor to the 13H3701 and serves as a functional and dimensional replacement.

Which Lennox models are compatible with this motor?
It is commonly found in Lennox CHA16, CHP16, CHP20, and GCS16 series units. Always verify the motor nameplate and rotation (CCWLE) before installation.
