This switch monitors negative pressure generated by the inducer motor during furnace operation. When the correct draft pressure is established, the switch closes to allow the control board to proceed through the ignition sequence. It is a direct service part intended for installation by licensed HVAC technicians performing pressure switch diagnostics or component replacement on qualifying furnace models.\u003c\/p\u003e\n\u003cp\u003eThe WESTINGHOUSE 632499R is specifically used on the G7SA Upflow\/Horizontal furnace configuration. This single-port design is appropriate for upflow and horizontal installations where a single pressure tap is required. Replacement is typically prompted by a failed draft-proving circuit, nuisance lockouts traced to the pressure switch circuit, or physical damage to the switch body or port fitting. Confirming inducer performance and hose integrity before replacing the switch is standard diagnostic practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.60 inches WC setpoint — normally open SPST configuration closes on rising negative pressure\u003c\/li\u003e\n  \u003cli\u003eSingle-port design matches original equipment port arrangement on G7SA furnaces\u003c\/li\u003e\n  \u003cli\u003eDirect OEM-style replacement — maintains original control board interlock logic\u003c\/li\u003e\n  \u003cli\u003eUpflow and horizontal installation compatible per G7SA application requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on the WESTINGHOUSE G7SA Upflow\/Horizontal Furnace as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePressure switch replacement on gas furnaces is performed by licensed HVAC technicians. Shut off power to the furnace at the disconnect switch and allow the system to de-energize before removing the switch or disconnecting wiring. Inspect the rubber pressure hose and inducer outlet port for cracks, blockages, or moisture before installing the new switch, as a faulty hose is a common root cause of pressure switch failure. Follow applicable local mechanical codes and the furnace manufacturer service instructions when reassembling and testing the draft-proving circuit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Pressure Switch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: Normally Open (NO) SPST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 0.60 inches WC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Configuration\u003c\/strong\u003e: Single Port\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: G7SA Upflow\/Horizontal 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: 632499R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284042875186,"sku":"632499R","price":36.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277896.jpg?v=1781067008","url":"https:\/\/voomisupply.com\/products\/westinghouse-632499r-furnace-pressure-switch-0-60-in-wc","provider":"Voomi Supply","version":"1.0","type":"link"}
