OEM Lennox ECM Blower Motor Assembly — 97W65

The genuine OEM Lennox 97W65 is a complete ECM (Electronically Commutated Motor) blower motor assembly engineered to move conditioned air through your Lennox furnace or air handler. This variable-speed motor modulates airflow to match system demand, delivering consistent comfort, quieter operation, and lower energy consumption than a standard PSC motor. Because it ships as a full assembly, installation is straightforward and factory-matched to your Lennox blower housing.

When an ECM blower motor begins to fail, you'll often notice weak or inconsistent airflow, the blower cycling on and off unexpectedly, unusual humming or grinding noises, error codes on the control board, or a complete loss of air movement even while the furnace fires. Ignoring these symptoms can strain the heat exchanger and reduce overall system efficiency.

Choosing OEM matters with Lennox equipment. The 97W65 is built to Lennox's exact electrical and mechanical specifications, ensuring proper communication with the furnace control board, correct rotation and torque, and a true drop-in fit. Aftermarket substitutes can cause airflow imbalances, nuisance faults, and premature failure. Protect your investment with the part Lennox specified.
