Lennox 35K59 Motor

The Lennox 35K59 Blower Motor is a high-performance 1/3 HP furnace motor designed for consistent airflow in residential and light commercial HVAC systems. Operating at 115V and 1075 RPM, this 4-speed motor offers versatile performance for air handlers and furnaces requiring precise cfm adjustments. Built on a 48 frame with a permanent split capacitor (PSC) design, it features a 1/2" x 3" shaft and is engineered for horizontal mounting using a belly band. This OEM replacement motor (cross-reference 47464-001) ensures proper static pressure handling and system efficiency. For professional installation, technicians should verify the 7.5 MFD 370 VAC capacitor and CCWLE rotation to match the existing blower wheel configuration. This robust motor replaces multiple legacy part numbers, including 88H79 and 49K70, providing a reliable solution for restoring peak airflow performance in Lennox and Allied Air equipment.

Common Questions:

What is the correct rotation for the 35K59?
This motor is specified for Counterclockwise Lead End (CCWLE) rotation. Always confirm your blower wheel’s directional requirement before installation.

Does this motor include the capacitor?
No, the 7.5 MFD 370 VAC capacitor is sold separately. It is a standard best practice to replace the run capacitor whenever installing a new blower motor.

Can this replace a 3-speed Lennox motor?
Yes, provided the voltage (115V), horsepower (1/3 HP), and physical frame match. The additional speed tap offers more flexibility for system balancing.
