OEM Lennox Blower Wheel — 45M36

The genuine OEM Lennox 45M36 blower wheel is the squirrel-cage fan that draws air across the heat exchanger or evaporator coil and pushes conditioned air through your ductwork. Precisely balanced from the factory, it delivers the correct airflow (CFM) your Lennox furnace or air handler needs for proper heating and cooling performance.

Over time a blower wheel can accumulate dirt, corrode, crack, or lose fins, throwing it out of balance. Common symptoms include weak or reduced airflow at the registers, loud rattling, humming, or vibration from the blower compartment, uneven room temperatures, and the blower motor running hot or tripping on overload. A dirty or damaged wheel forces the motor to work harder, driving up energy use and shortening its lifespan.

Installing the OEM Lennox 45M36 guarantees the exact diameter, width, bore, and rotation your equipment was designed around. Aftermarket wheels that don't match specification can create balance and airflow problems that stress the motor and bearings. The factory part restores quiet, efficient, properly balanced airflow for your Lennox system.
