The genuine OEM Lennox 28G87 fan motor is a factory-specified replacement built to power the fan or blower assembly in compatible Lennox HVAC units. It circulates air across the coil and through the ductwork, and its speed, torque, and rotation are precisely matched to the system's design airflow to maintain proper comfort and efficiency.
Common failure symptoms: Warning signs of a worn motor include loud humming, rattling, or squealing, reduced or absent airflow, the motor overheating and cycling on its internal overload, or the fan failing to start altogether. Aging bearings and degraded windings can also cause breaker trips, short cycling, or an electrical burning odor near the unit.
Why OEM matters: Lennox engineers each motor to specific electrical and mechanical tolerances, including horsepower, RPM, capacitor rating, and mounting geometry. The authentic 28G87 drops in without adaptation and delivers the exact performance your system was designed for, unlike generic motors that risk airflow problems and early failure. Installing genuine OEM safeguards the reliability and rated efficiency of your Lennox equipment.
