The genuine OEM Lennox 67M64 draft inducer motor assembly draws combustion byproducts through the heat exchanger and exhausts them safely out the flue. It energizes at the start of every heating cycle to establish a proper draft and close the pressure switch, giving the control board the green light to ignite the burners. Engineered to Lennox specifications, the 67M64 delivers the exact airflow your furnace needs for safe, efficient heating.
Common failure symptoms: no ignition despite a call for heat, rattling or buzzing noises when the furnace starts, short-cycling, or repeated pressure-switch lockout codes. These usually point to failed bearings, a cracked or unbalanced inducer wheel, or an open motor winding.
Why OEM matters: The pressure switch and combustion safeties on Lennox furnaces are calibrated to the OEM inducer's specific airflow and vacuum. Installing the factory 67M64 ensures a bolt-in fit with the correct wheel and gasket sealing surfaces, avoiding nuisance faults and keeping your system within its certified efficiency and safety limits — reliability that generic replacements often compromise.
