It creates the negative pressure the pressure switch verifies before ignition, ensuring the burners fire only when proper venting airflow is established. This assembly is fundamental to both the safety and efficiency of the heating cycle.\u003c\/p\u003e\u003cp\u003eSymptoms of a failing \u003cstrong\u003e47M55\u003c\/strong\u003e include the furnace failing to ignite, a pressure switch fault code, loud humming, grinding, or rattling noises at startup, or a motor that runs slowly or not at all. Worn bearings, a seized wheel, or an open winding will prevent the pressure switch from closing, locking out the entire heating sequence.\u003c\/p\u003e\u003cp\u003eOEM matters because the \u003cstrong\u003e47M55\u003c\/strong\u003e delivers the exact airflow, RPM, and housing fit engineered for your Lennox furnace. A generic inducer may not generate the correct draft to satisfy the pressure switch or match the venting requirements, causing repeated lockouts. Install the factory-matched assembly to restore safe combustion, reliable ignition, and rated heating performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081104933235,"sku":"LNX-47M55","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-47M55.jpg?v=1783760240","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-draft-inducer-motor-assembly-47m55","provider":"National HVAC Parts","version":"1.0","type":"link"}
