OEM Lennox Condenser Fan Motor — Y8764

The genuine OEM Lennox Y8764 condenser fan motor spins the fan blade in the outdoor unit of your Lennox air conditioner or heat pump. It pulls ambient air across the condenser coil to reject the heat absorbed from inside your home. This airflow is essential to condensing the refrigerant back into a liquid and keeping the system operating at its rated efficiency and pressure.

Common failure symptoms include an outdoor fan that won't spin, a unit that runs but doesn't cool, high head pressure that trips the compressor on overload, a humming motor that never starts, or a blade that spins slowly. Failed bearings, an open winding, or a shorted run capacitor circuit are frequent causes, and overheating outside the unit is a telltale sign.

Why OEM matters: the Lennox Y8764 matches the exact horsepower, RPM, rotation, and capacitor rating your condenser was designed around. An incorrectly matched aftermarket motor can move too little air, overload the compressor, or fail early from improper amperage. The factory part ensures correct fit, proper heat rejection, and long, reliable service for your Lennox outdoor unit.
