OEM Lennox Brushless DC Fan Motor — Y9507

The genuine OEM Lennox Y9507 is a brushless DC (ECM) fan motor engineered to drive the blower or condenser fan in your Lennox HVAC system. Its electronically commutated design delivers precise, variable-speed airflow that improves comfort, dehumidification, and energy efficiency compared with older single-speed motors. Because it is factory-matched to Lennox control boards, the Y9507 responds correctly to the system's speed commands right out of the box.

Common failure symptoms: When a brushless DC fan motor begins to fail, you may notice the fan starting and stopping intermittently, running at the wrong speed, humming or clicking without spinning, weak airflow at the registers, or a system error code reported by the control board. Overheating and hard shutdowns are also frequent signs of a worn motor or failing module.

Why OEM matters: Aftermarket motors often lack the exact winding specifications, module programming, and mounting geometry that Lennox equipment expects, which can cause airflow errors, premature failure, or void your warranty. Installing the authentic Lennox Y9507 guarantees correct fit, rated performance, and full compatibility with your unit's electronics for reliable, long-term operation.
