Lennox 12M55 Inducer Assembly

The Lennox 12M55 Inducer Assembly is a critical OEM replacement part designed for high-efficiency thermal performance in Lennox residential furnaces. This unit, also identified as the Lennox 12M5501, features a Fasco motor rated at 1/25 HP, operating at 208-230V and 3200 RPM. Engineered for durability, the draft inducer blower utilizes a robust metal housing and a steel wheel to facilitate precise flue gas exhaustion, ensuring the pressure switch closes consistently for a safe ignition sequence. As a veteran-grade furnace inducer motor, it replaces several legacy components, including 20L09, 42H00, and the LB-62533 series. During installation, verify the CWLE rotation (Clockwise Lead End) matches your existing blower configuration. This assembly includes the lead wires and transition gaskets required to restore optimal combustion airflow and prevent common pressure switch fault codes in Lennox HVAC systems.

• Direct OEM Compatibility: Ensures a drop-in fit for Lennox 12M55 and 12M5501, maintaining the original factory sequence of operation.
• High-Speed Performance: The 3200 RPM motor provides the necessary static pressure to clear the heat exchanger of combustion byproducts.
• Industrial Build Quality: Features a thermally protected motor and dual-sealed ball bearings for reduced operational noise and extended service life.
• Broad Application: Serves as a versatile replacement for various Allied, Armstrong, and Ducane part numbers.

• Is the Lennox 12M55 interchangeable with the 12M5501? Yes, these part numbers refer to the same draft inducer assembly and are functionally identical for all Lennox applications.
• Why is my furnace giving a pressure switch error? A failing inducer motor often fails to reach the required RPM or has a clogged inducer housing, preventing the pressure switch from sensing the necessary draft. Replacing the 12M55 assembly typically resolves this issue.
• Does this include the necessary gaskets? This genuine Lennox part is supplied as a complete assembly, designed to include the essential mounting components for a leak-free seal.
