The genuine OEM Lennox 67M61 draft inducer motor assembly is the venting blower responsible for evacuating flue gases from your furnace's heat exchanger and expelling them through the exhaust pipe. It runs a brief pre-purge before ignition to build a safe draft and satisfy the pressure switch, allowing the burners to light. Built to Lennox factory tolerances, the 67M61 restores correct combustion airflow and dependable furnace performance.
Common failure symptoms: a furnace that clicks but never fires, loud squealing or grinding at cycle start, intermittent heat, or recurring pressure-switch error codes. Worn bearings, debris in the wheel, or an electrical winding failure are the usual culprits behind a dead inducer.
Why OEM matters: Lennox furnaces depend on the inducer's precise CFM and vacuum to pass safety interlocks and burn cleanly. The OEM 67M61 arrives with the exact housing, wheel balance, and mounting geometry your unit expects, delivering a true drop-in replacement that prevents nuisance lockouts and preserves the rated efficiency an aftermarket motor may not reproduce.
