It monitors negative pressure generated by the inducer motor during furnace startup and operation, confirming proper venting before allowing ignition to proceed. The switch features dual set points of 1.40 and 0.30 inches water column (WC), corresponding to the low-fire and high-fire stages of a 2-stage furnace. Licensed HVAC technicians install this component as part of routine service or fault diagnosis on condensing furnace systems.\u003c\/p\u003e\n\u003cp\u003eThis switch is specified for use on 120-VD condensing gas furnaces. Condensing furnaces operate with high-efficiency heat exchangers and sealed combustion or induced-draft venting systems where inducer pressure verification is a critical safety interlock. A failed or out-of-range pressure switch is a common cause of fault codes related to inducer or draft proving failures on 2-stage systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual set points at 1.40 inches WC and 0.30 inches WC for 2-stage furnace operation\u003c\/li\u003e\n  \u003cli\u003eDesigned for condensing gas furnace applications with induced-draft venting\u003c\/li\u003e\n  \u003cli\u003eFunctions as a safety interlock, preventing ignition when inducer pressure is out of range\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement for 120-VD series condensing gas furnace platforms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on 120-VD condensing gas furnaces as specified by the manufacturer.

Shut off power to the furnace at the disconnect or breaker before removing the existing switch. Inspect the rubber hose or tubing connected to the pressure port for cracks or blockages, as degraded tubing is a frequent cause of pressure switch faults. Follow all applicable local codes and the furnace manufacturer's service documentation when replacing safety-interlock components.\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: 1.40 inches WC and 0.30 inches WC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStage Configuration\u003c\/strong\u003e: 2-Stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Condensing Gas Furnace\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: 120-VD 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: 632567\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51283967476018,"sku":"632567","price":72.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277893.jpg?v=1781064492","url":"https:\/\/voomisupply.com\/products\/westinghouse-632567-gas-furnace-pressure-switch-2-stage","provider":"Voomi Supply","version":"1.0","type":"link"}
