OEM Lennox Draft Inducer Blower Motor — 20P68

The genuine OEM Lennox 20P68 is a draft inducer blower motor that drives the inducer assembly on your Lennox gas furnace. Its job is to pull combustion gases through the heat exchanger and push them safely out the flue, creating the negative pressure the pressure switch needs to prove venting before the burners light. Without a healthy inducer motor, your furnace simply won't fire.

Common failure symptoms include a furnace that hums or clicks but never ignites, loud grinding or rattling from the inducer housing at startup, a motor that runs slow or seizes, and repeated lockouts tied to an open pressure switch. Worn bearings, a burned winding, or a failed capacitor circuit are typical culprits — often preceded by an intermittent no-heat call.

Why OEM matters: Lennox engineers the 20P68 to the exact RPM, torque, and airflow spec your furnace's control board and pressure switch expect. A generic substitute can vent too weakly to close the switch or run out of spec, risking nuisance lockouts, safety faults, and premature heat exchanger wear. Choosing the factory-matched 20P68 restores rated performance and protects your warranty. In stock and shipping same day before 3PM CST.
