OEM Lennox Fan Motor — 15C76

The genuine OEM Lennox 15C76 fan motor turns the fan blade that circulates air through your Lennox system, providing the steady airflow required for efficient heat exchange and consistent comfort. It is built to the precise horsepower, speed, rotation, voltage, and frame dimensions Lennox calls out for your model, so it installs as a true bolt-in replacement.

Common symptoms of a worn fan motor include noisy or grinding bearings, a fan that hesitates, runs slow, or fails to start, overheating that trips the breaker or thermal overload, and reduced cooling or heating performance. In many cases a bad motor will also take out the run capacitor, so both are worth inspecting together.

Using OEM is important on Lennox equipment because the motor is matched to the blade pitch, cabinet airflow, and control wiring. An off-spec substitute can spin at the wrong speed, draw excess current, and stress the capacitor or control board. The 15C76 is a direct factory replacement that restores designed airflow, protects surrounding components, and keeps your system running quietly and efficiently.
