The genuine OEM Lennox 12G73 fan motor drives the fan that moves air across your Lennox unit's coil, a job essential to proper heat transfer and system efficiency. Whether pulling air through the outdoor condenser or circulating it indoors, this motor keeps airflow at the volume your Lennox equipment was designed to deliver, protecting the compressor from overheating and maintaining rated capacity.
Common failure symptoms: A failing 12G73 motor may hum without starting, run hot and cut out on its thermal overload, spin slowly, produce grinding or squealing bearing noise, or stop entirely. You may notice weak airflow, the compressor tripping on high pressure, or the unit not cooling despite running.
Why OEM matters: The Lennox 12G73 is matched to the correct horsepower, RPM, voltage, rotation, and shaft specifications for your system. A mismatched aftermarket motor can move too little or too much air, overload the capacitor, or fail prematurely. Choosing the factory OEM motor ensures a direct fit, proper airflow, and long service life in your Lennox equipment.
