OEM Lennox Combustion Air Blower, 2-Speed — 16X30

The Lennox 16X30 is a genuine OEM 2-speed combustion air blower (draft inducer) built for Lennox gas furnaces. It pulls fresh combustion air through the burners and pushes exhaust gases out through the flue, establishing the pressure the furnace's pressure switch needs before the ignition sequence can begin. The two-speed design lets the furnace match airflow to each firing stage for quieter, more efficient operation.

Common failure symptoms: the furnace will not ignite or locks out on a pressure-switch fault, you hear loud humming, grinding, or rattling from the inducer at startup, the motor runs hot or cycles on and off, or the blower fails to spin up at all. Worn bearings, a seized wheel, or an open winding are typical causes.

Why OEM matters: the 16X30 is engineered to the exact CFM, wheel geometry, and electrical spec your Lennox control board expects. An OEM unit keeps the pressure switch calibrated correctly and preserves the furnace's safety and efficiency ratings — a generic substitute can throw pressure faults, shorten motor life, or void warranty coverage.
