OEM Lennox Fan Motor — 72H73

The genuine OEM Lennox 72H73 fan motor drives the fan blade that moves air across your system's coil, a job that is essential for proper heat transfer and efficient operation. When this motor weakens or fails, airflow drops, refrigerant pressures climb, and your Lennox unit can no longer cool or heat as designed.

Common failure symptoms: a fan that hums but won't spin, a blade that spins slowly or stops entirely, loud grinding or squealing from worn bearings, a motor that runs hot and cuts out on thermal overload, or a system that trips on high-pressure and short-cycles. A failed condenser fan motor is a frequent cause of warm air from the vents on the hottest days.

Why OEM matters: the Lennox 72H73 is matched to the correct horsepower, RPM, rotation direction, voltage, and shaft dimensions for your equipment. A mismatched aftermarket motor can spin the wrong direction, overheat, or fail to move enough air, hurting efficiency and shortening compressor life. Choosing the factory 72H73 guarantees the right electrical and mechanical fit for dependable, rated performance.
