This pre-purge and venting action is essential for safe operation, and the pressure switch relies on the inducer establishing proper airflow before the gas valve is allowed to open.\u003c\/p\u003e\u003cp\u003eWhen a draft inducer motor wears out, you'll often hear loud humming, grinding, or rattling from the furnace, notice the blower failing to start, or find the system locked out on a pressure-switch fault. Failed bearings or a seized motor will prevent the furnace from igniting at all.\u003c\/p\u003e\u003cp\u003eThe OEM \u003cstrong\u003e99K57\u003c\/strong\u003e arrives as a complete assembly matched to your Lennox furnace's airflow and mounting requirements, including the correct blower wheel and housing. Aftermarket substitutes can deliver incorrect CFM that trips the pressure switch or causes incomplete combustion. This factory-authorized part restores proper draft, safe venting, and reliable ignition.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081090384243,"sku":"LNX-99K57","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-99K57.jpg?v=1783760264","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-draft-inducer-motor-assembly-99k57","provider":"National HVAC Parts","version":"1.0","type":"link"}
