OEM Lennox Draft Inducer Motor Assembly w/ Gasket — 16A66

The genuine OEM Lennox 16A66 draft inducer motor assembly, supplied complete with its mounting gasket, pulls combustion gases through the heat exchanger and pushes them out the flue before and during furnace operation. This forced draft is what allows the pressure switch to close and the ignition sequence to begin, making the inducer one of the most critical components in your Lennox furnace.

Common symptoms of a failing inducer include a loud humming or grinding noise at startup, a motor that runs slowly or not at all, an open pressure switch that halts ignition, and a furnace that repeatedly locks out on error. Worn bearings and burned windings are typical failure points after years of thermal cycling.

Installing the OEM Lennox 16A66 ensures the correct airflow rating, blower wheel balance, and electrical characteristics your furnace's control board expects. Because it ships with the matching gasket, you get a complete, leak-free installation. Aftermarket substitutes can move the wrong volume of air and cause chronic pressure switch faults — this factory assembly restores reliable, safe venting.
