OEM Lennox Fan Motor — 12U70

The genuine OEM Lennox 12U70 fan motor is responsible for moving air through your Lennox system, turning the blower or condenser fan to circulate air across the coil for effective heat transfer. Manufactured to the original Lennox specification, it serves as a true drop-in replacement for the factory motor.

Telltale signs of a failing fan motor include reduced or inconsistent airflow, warm air where you expect cool, noisy operation such as humming, rattling, or squealing, a fan that won't start on its own, and a motor that runs hot and cuts out on its thermal overload. Addressing it promptly prevents added strain on the compressor and rising energy costs.

The OEM 12U70 is the right choice for your Lennox equipment because it's matched to the correct RPM, rotation, voltage, and bearing load your unit requires. Generic alternatives commonly miss one of these specifications and lead to noise, inefficiency, or early failure. This authentic factory part protects your warranty and delivers the fit, performance, and longevity Lennox engineered into your system.
