The genuine OEM Lennox Y4649 draft inducer blower motor operates the combustion venting system on compatible Lennox gas furnaces. It turns the inducer wheel to draw exhaust gases through the heat exchanger and expel them through the flue, establishing the airflow your furnace's pressure switch verifies before ignition is permitted.

Common failure symptoms include an inducer that hums but won't spin, loud grinding or squealing at startup, a motor that runs slowly or stalls, and repeated pressure-switch lockouts that leave you without heat. Worn bearings and failed motor windings are the most frequent causes, often preceded by intermittent starting problems and short cycling.

Why OEM matters: The Y4649 delivers the precise speed and airflow that your Lennox ignition sequence depends on. Non-OEM motors frequently vent too weakly to satisfy the pressure switch or run outside factory spec, causing nuisance lockouts, unreliable heating, and premature heat exchanger stress. The factory-correct Y4649 restores proper draft, dependable ignition, and rated efficiency while keeping your equipment warranty valid. In stock and shipping same day before 3PM CST.
