It generates the induced draft that moves combustion gases through the heat exchanger and out the vent, producing the pressure the safety switch must sense before the furnace will light and fire safely.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms\u003c\/strong\u003e include a furnace that energizes the inducer but never ignites, rattling, grinding, or high-pitched squealing from the inducer housing, sluggish or seized motor operation, and repeated lockouts from an open pressure switch. These issues usually trace back to worn bearings, a burned winding, or general age-related wear, often starting as occasional no-heat calls.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The Y4642 is matched to the exact RPM, torque, and airflow your Lennox control board and pressure switch expect. A generic motor can vent too weakly to prove draft or run out of spec, leading to nuisance lockouts, inconsistent heat, and added strain on the heat exchanger. Installing the factory-correct Y4642 restores reliable venting and rated performance while protecting your warranty.
