This factory assembly pairs the motor with a precisely matched blower housing, creating the negative pressure your furnace needs to close the pressure switch and begin a safe ignition cycle. Reliable draft is essential to both furnace efficiency and safe operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A worn \u003cstrong\u003e12M55\u003c\/strong\u003e inducer commonly announces itself with grinding, squealing, or loud humming at startup, intermittent spinning, or complete failure to start. Since the pressure switch relies on inducer airflow, a failing motor frequently causes ignition lockouts and pressure-switch fault codes. Seized bearings and failed windings are the usual causes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Lennox engineers each inducer assembly to produce a specific airflow and RPM tuned to the furnace's venting and safety systems. Generic replacements can under- or over-draft, triggering pressure faults or poor combustion. The OEM \u003cstrong\u003e12M55\u003c\/strong\u003e guarantees the correct airflow, mounting pattern, and wiring connector for a dependable, code-compliant fit in your Lennox furnace.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081115648371,"sku":"LNX-12M55","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-12M55.jpg?v=1783760225","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-draft-inducer-motor-assembly-12m55","provider":"National HVAC Parts","version":"1.0","type":"link"}
