OEM Lennox Draft Inducer Motor Assembly — 83M56

The genuine OEM Lennox 83M56 draft inducer motor assembly pulls combustion gases through the heat exchanger and safely vents them out of your furnace before and during the burner cycle. Built to exact Lennox specifications, this complete assembly ensures proper draft, correct pressure-switch operation, and safe, efficient combustion.

Common signs of a failing draft inducer include the furnace not starting, a loud humming or grinding noise on startup, rattling or squealing from worn bearings, a pressure-switch fault code, or the blower running but no ignition following. Because the inducer must prove airflow before the gas valve opens, a bad motor typically results in a no-heat condition and repeated lockouts.

OEM matters for Lennox equipment because the 83M56 is matched to the exact CFM, housing dimensions, and electrical draw your furnace requires — off-brand substitutes can misread the pressure switch, disrupt venting, and compromise safety. This factory assembly drops in for correct draft and dependable operation, safeguarding both efficiency and your Lennox warranty.
