OEM Lennox Draft Inducer Motor Assembly — 14L67

The genuine OEM Lennox 14L67 draft inducer motor assembly pulls combustion gases through the heat exchanger and pushes them safely out the flue before and during furnace operation. This assembly is matched to the exact airflow, mounting, and pressure specifications of your Lennox furnace, ensuring the pressure switch proves properly and the ignition sequence completes every cycle.

A failing draft inducer typically announces itself through loud humming, grinding, or rattling noises, a furnace that clicks but never lights, or repeated lockouts caused by a pressure switch that won't close. Worn bearings, a seized blower wheel, or an open motor winding all interrupt safe venting and prevent the furnace from firing, leaving you without heat.

OEM is critical for this safety component: the 14L67 delivers the precise draft and vacuum your Lennox pressure switch is calibrated to detect, so combustion byproducts vent correctly and dangerous flue gases never back up into the home. Installing the factory assembly restores reliable ignition, protects the heat exchanger, and preserves your Lennox warranty.
