OEM Lennox Fan Motor — 38W84

The genuine OEM Lennox 38W84 fan motor drives the fan that moves air through your Lennox HVAC equipment, whether pulling air across the condenser coil in the outdoor unit or circulating conditioned air indoors. Proper airflow is essential for heat transfer and system efficiency, making this motor a core component of reliable heating and cooling performance.

Common failure symptoms: A failing 38W84 motor may run hot and cut out on thermal overload, hum without spinning, produce grinding or squealing bearing noise, or stop entirely — leading to warm air, poor cooling, a unit that overheats, or high-pressure trips. Worn bearings and open windings are typical end-of-life failures.

Why OEM matters: Fan motors must match precise specifications for horsepower, voltage, RPM, rotation direction, and shaft size. The Lennox 38W84 is engineered to your unit's exact requirements, ensuring correct airflow, proper amp draw, and long service life. A close-enough aftermarket motor risks improper airflow, premature failure, and strain on other components — which is why the factory-specified motor is the safe, lasting choice for your Lennox system.
