It monitors combustion air pressure to verify proper inducer operation before allowing burner ignition, protecting against flue-gas backdraft and inducer failure. This switch carries dual set points of 0.73 inches WC and 0.43 inches WC, corresponding to the high-fire and low-fire stages of a 2-stage furnace. Installation is performed by licensed HVAC technicians as part of routine pressure switch replacement or combustion safety system service.\u003c\/p\u003e\n\u003cp\u003eThis pressure switch is specified for use on the MGC2 2-stage condensing and non-condensing furnace platform. The dual set-point design supports proper sequencing across both firing stages, ensuring the control board receives correct pressure confirmation signals at each stage of operation. It is suited for residential and light-commercial gas furnace systems where 2-stage burner control is employed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual set points: 0.73 inches WC (high fire) and 0.43 inches WC (low fire)\u003c\/li\u003e\n  \u003cli\u003eNormally open (NO) contact configuration\u003c\/li\u003e\n  \u003cli\u003eDesigned for 2-stage condensing and non-condensing furnace operation\u003c\/li\u003e\n  \u003cli\u003eMonitors inducer pressure to enable safe burner ignition sequencing\u003c\/li\u003e\n  \u003cli\u003eDirect OEM replacement for MGC2 platform furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on MGC2 2-Stage Condensing and Non-Condensing Furnaces as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePressure switch replacement is performed by a qualified HVAC technician. Before servicing, shut off power to the furnace at the disconnect and allow the inducer to come to a complete stop. The switch connects to the inducer housing port via a rubber hose; inspect the hose and port for cracks or blockages before installing the new switch. Follow local mechanical codes and the furnace manufacturer service manual for torque and wiring procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Pressure Switch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Points\u003c\/strong\u003e: 0.73 inches WC \/ 0.43 inches WC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: Normally Open (NO)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStage\u003c\/strong\u003e: 2-Stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Condensing and Non-Condensing Gas 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: 632515R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284007911730,"sku":"632515R","price":60.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277890.jpg?v=1781065860","url":"https:\/\/voomisupply.com\/products\/westinghouse-632515r-furnace-pressure-switch-0-73-0-43-wc-2-stage","provider":"Voomi Supply","version":"1.0","type":"link"}
