The genuine OEM Lennox 47H12 draft inducer motor assembly pulls combustion gases through the heat exchanger and safely vents them out of your furnace before the burners ignite. It creates the negative pressure the pressure switch needs to prove proper draft, making it a critical safety and performance component in compatible Lennox gas furnaces.
A failing 47H12 often announces itself with loud humming, rattling, or grinding noises, a furnace that won't ignite, repeated pressure-switch lockouts, or a blower wheel that spins slowly or seizes. Worn bearings, a burned-out motor winding, or a cracked inducer housing are typical causes of failure.
OEM matters here because the 47H12 is precisely balanced and airflow-rated for your Lennox model — a mismatched inducer can starve the burners of draft or trip safety controls. This factory assembly ensures correct RPM, proper venting, and reliable pressure-switch operation, restoring safe, efficient heating to your Lennox furnace.
