It creates the induced draft that pulls combustion byproducts through the heat exchanger and out the vent, generating the pressure differential the safety switch must confirm before the burners can light.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms\u003c\/strong\u003e include a furnace that runs the inducer but won't ignite, grinding, whining, or rattling noises from the inducer housing, slow or intermittent motor operation, and repeated lockouts caused by an open pressure switch. Bearing wear, a shorted winding, or age-related fatigue typically precede complete failure, often showing up first as random no-heat events.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The Y4637 is engineered to the exact RPM and airflow your Lennox furnace's board and pressure switch are calibrated for. A generic replacement can under-vent, fail to close the switch, or operate out of spec — inviting nuisance faults, unreliable heating, and extra wear on the heat exchanger. The factory-matched Y4637 restores dependable draft and rated performance while preserving your warranty.
