Operating on 115 volts, it provides four selectable speed taps, giving technicians the flexibility to match airflow to the specific duct system and furnace configuration. The counterclockwise (CCW) shaft rotation is critical to proper blower wheel performance and must be confirmed before installation. This motor is installed by HVAC technicians as a direct replacement in gas, oil, or electric furnaces where the original blower motor has failed or degraded.\u003c\/p\u003e\n\u003cp\u003eThis motor is suited for forced-air furnace applications where a 1\/2 HP, 4-speed, 115-volt blower motor is required. The four speed taps allow adjustment for heating and, where applicable, cooling airflow demands within a single system. CCW rotation makes this motor appropriate for blower assemblies that require a specific shaft direction to move air efficiently through the heat exchanger and into the supply plenum. It is typically found in residential furnace installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1\/2 HP output suited for residential furnace blower assemblies\u003c\/li\u003e\n\u003cli\u003e115-volt single-phase operation compatible with standard residential electrical service\u003c\/li\u003e\n\u003cli\u003eFour speed taps provide airflow flexibility across heating and cooling modes\u003c\/li\u003e\n\u003cli\u003eCounterclockwise (CCW) shaft rotation matches specific blower wheel configurations\u003c\/li\u003e\n\u003cli\u003eOEM-style replacement designed to restore original furnace airflow performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement blower motor for residential forced-air furnaces requiring a 1\/2 HP, 115-volt, 4-speed, CCW rotation motor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician. Always disconnect and lock out electrical power at the disconnect switch before removing the existing motor or handling wiring. Verify shaft rotation direction, speed tap wiring, and mounting orientation match the original motor before energizing the unit. Consult local electrical codes and the furnace manufacturer service documentation for any jurisdiction-specific requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 1\/2 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 115 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeeds\u003c\/strong\u003e: 4-Speed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotation\u003c\/strong\u003e: Counterclockwise (CCW)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 904859\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284060242226,"sku":"904859","price":437.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278105.jpg?v=1781067468","url":"https:\/\/voomisupply.com\/products\/westinghouse-904859-furnace-blower-motor-1-2-hp-4-speed","provider":"Voomi Supply","version":"1.0","type":"link"}
