The inducer motor moves combustion gases through the heat exchanger and out the flue, maintaining proper draft throughout the combustion cycle. It is a direct component in the venting system and is typically replaced by a licensed HVAC technician during a furnace service or failure diagnosis. The variable-speed design allows the motor to adjust airflow based on system demand, supporting consistent combustion performance in downflow furnace configurations.\u003c\/p\u003e\u003cp\u003eThis inducer motor is engineered for use in downflow non-condensing gas furnace applications. Downflow furnaces discharge heated air downward through the supply plenum, and the inducer motor plays a critical role in maintaining negative pressure across the heat exchanger during operation. This part is suited for residential gas heating systems where the original OEM inducer motor has failed or requires replacement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable-speed motor operation for demand-matched draft control\u003c\/li\u003e\n\u003cli\u003eDesigned for downflow non-condensing gas furnace configurations\u003c\/li\u003e\n\u003cli\u003eOEM-style replacement for direct fit and function\u003c\/li\u003e\n\u003cli\u003eSupports proper combustion gas evacuation through the flue system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on the 140-45D1 Non-Condensing Gas Furnace.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Before servicing, shut off gas supply and disconnect electrical power to the furnace at the disconnect switch or breaker. The inducer motor assembly typically mounts to the inducer housing with fasteners and connects to the control board via a wiring harness — inspect the housing gasket for damage before reinstalling. Follow all applicable local mechanical and gas codes, including IFGC guidelines, when servicing combustion system components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Inducer Motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Speed\u003c\/strong\u003e: Variable Speed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow Direction\u003c\/strong\u003e: Downflow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFurnace Type\u003c\/strong\u003e: Non-Condensing Gas Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WESTINGHOUSE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 904979\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284053655858,"sku":"904979","price":418.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278142.jpg?v=1781067279","url":"https:\/\/voomisupply.com\/products\/westinghouse-904979-gas-furnace-inducer-motor","provider":"Voomi Supply","version":"1.0","type":"link"}
