OEM Lennox Blower Motor — 86W87

The genuine OEM Lennox 86W87 blower motor drives the indoor fan that circulates conditioned air through the ductwork of your Lennox furnace or air handler. Properly matched airflow is essential to safe combustion, effective heat transfer, and even temperatures throughout the home. This factory-specified motor delivers the correct speed and torque your Lennox system was engineered around.

Telltale signs of a failing blower motor include weak airflow from the registers, the fan not spinning at all, loud humming, squealing, or grinding, a motor that runs hot or trips on thermal overload, and frequent system short-cycling. Because the blower shares its load with the heat exchanger, a failing 86W87 can also cause the furnace to overheat and lock out on a limit fault.

For Lennox equipment, OEM is the safe choice. The 86W87 meets Lennox's exact electrical and dimensional standards for a true bolt-in replacement and proper integration with the control system. Aftermarket motors risk airflow mismatches, vibration, and shortened service life. Keep your Lennox running as designed with the genuine part.
