On Lennox gas furnaces, the inducer creates negative pressure to safely pull combustion gases through the heat exchanger and out the flue, and this gasket is what keeps that pressure boundary intact. Even a small seal failure lets flue gases and air leak past the joint, undermining safe and efficient venting.\u003c\/p\u003e\u003cp\u003eCommon symptoms of a worn or cracked \u003cstrong\u003e46K90\u003c\/strong\u003e gasket include a whistling or air-rushing sound near the inducer, pressure-switch faults that lock out ignition, nuisance error codes, and reduced heating performance. Hardened, brittle, or crushed gasket material after years of heat cycling is a frequent culprit.\u003c\/p\u003e\u003cp\u003eChoosing the OEM Lennox \u003cstrong\u003e46K90\u003c\/strong\u003e gasket ensures the exact thickness, bolt-hole pattern, and high-temperature material Lennox engineered for your specific inducer assembly. Generic substitutes may not seal correctly, risking pressure-switch problems or combustion-gas leaks. Installing the factory-specified part restores a proper seal and protects the safe operation of your Lennox furnace.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081105490291,"sku":"LNX-46K90","price":159.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-draft-inducer-LNX-46K90.jpg?v=1783760204","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-draft-inducer-gasket-46k90","provider":"National HVAC Parts","version":"1.0","type":"link"}
