The genuine OEM Lennox Y8766 draft inducer blower motor assembly is a complete, factory-matched unit that moves combustion gases through the heat exchanger and vents them out the flue on compatible Lennox furnaces. Supplied as an integrated motor-and-housing assembly, the Y8766 makes replacement straightforward while restoring the exact draft and airflow your furnace was designed around.

Common failure symptoms include a furnace humming without ignition, loud rattling or grinding at startup, a pressure switch that won't close, recurring ignition lockouts, or a total loss of heat. Failed bearings, a damaged housing, or a burned-out winding within the assembly are the usual causes.

Why OEM matters: Lennox engineers the Y8766 assembly to precise speed, torque, and static-pressure standards that match the furnace's venting and pressure-switch requirements. Choosing the authentic OEM assembly guarantees proper draft, reliable safety operation, and quiet, durable performance that generic parts seldom match. Restore your Lennox furnace to manufacturer specification with the complete factory assembly.
