OEM Lennox Condenser Fan Motor — 11F04

The genuine OEM Lennox 11F04 condenser fan motor drives the fan blade in your outdoor condensing unit, pulling air across the condenser coil to reject heat absorbed from your home. Without steady, correctly-rated airflow, refrigerant pressures climb, cooling capacity drops, and the compressor is forced to work harder — making this one of the most critical components in your Lennox system.

Common failure symptoms include a fan that hums but won't spin, a motor that starts then stops as it overheats, grinding or squealing bearings, intermittent operation on hot days, and a compressor that trips on high-pressure lockout. A failed 11F04 often leaves the fan blade motionless while the rest of the unit still tries to run.

Why OEM matters: Lennox engineers this motor to exact horsepower, RPM, rotation, and mounting specifications for your equipment. Generic substitutes can mismatch bearing loads, capacitor requirements, and airflow ratings — leading to premature failure and reduced efficiency. Choosing the factory 11F04 guarantees correct fit, rated performance, and the longest service life for your Lennox condenser.
