The genuine OEM Lennox 14B91 draft inducer blower motor powers the combustion venting on your Lennox furnace. It spins the inducer wheel to pull flue gases through the heat exchanger and push them safely out the vent, while creating the pressure differential the pressure switch needs to prove draft and allow ignition.

A failing inducer motor is a common cause of no-heat calls. Watch for loud humming, grinding, or squealing at startup, a motor that runs hot or cycles on thermal overload, intermittent pressure-switch lockouts, or a furnace that will not begin its ignition sequence at all. Worn bearings and weak windings are typical failure points as the motor ages.

The OEM Lennox 14B91 is matched to your furnace's exact airflow, RPM, and electrical requirements, so it seats correctly against the inducer housing and proves draft as designed. Generic motors can move the wrong CFM, cause pressure-switch faults, or fit poorly against the gasket surface. Install the factory-specified motor to restore safe, reliable venting and full heating performance for your Lennox equipment.
