OEM Lennox Fan Motor — 12Y65

The genuine OEM Lennox 12Y65 fan motor drives the fan that moves air across your Lennox system's coil, delivering the airflow required for proper heat exchange and efficient operation. Built to factory specifications for voltage, horsepower, RPM, and rotation, this motor provides dependable, long-lasting performance and is a direct replacement for the original unit.

Common failure symptoms: A failing fan motor may run hot and shut down on thermal overload, hum without starting, spin slowly, make grinding or squealing bearing noises, or stop entirely. When the motor quits, you'll often see the compressor overheat and trip, warm air instead of cool, or a high-pressure lockout as heat can no longer be rejected from the coil.

Why OEM matters: Fan motors must match the exact horsepower, speed, rotation, bearing type, and mounting of your Lennox unit — along with the correct capacitor rating — to move the designed airflow and avoid overheating. A mismatched aftermarket motor can overload, reduce capacity, and void warranty coverage. The OEM 12Y65 ensures a precise fit and factory-rated performance for a reliable repair.
