Pressure switches monitor the negative pressure created by the draft inducer motor during furnace operation. When the inducer establishes proper airflow, the switch closes and signals the control board to continue the ignition sequence. If pressure drops below the set point, the switch opens and locks out the furnace as a safety measure. This part is intended for installation by licensed HVAC technicians servicing gas furnaces.\u003c\/p\u003e\n\u003cp\u003eThe 632493R is designed for use on the G7SC-1 Upflow\/Horizontal furnace. This switch is appropriate for residential gas furnace applications where the appliance is installed in an upflow or horizontal orientation. Pressure switches in this category are a common service item, typically replaced when a furnace fails to advance past the inducer-proving stage of the startup sequence.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.60 inches WC setpoint for accurate draft proving during furnace startup\u003c\/li\u003e\n  \u003cli\u003eSPST configuration provides a simple open\/close signal to the furnace control board\u003c\/li\u003e\n  \u003cli\u003eSingle-port design for straightforward hose connection to the inducer housing or collector box\u003c\/li\u003e\n  \u003cli\u003eServes as a safety interlock, shutting down the ignition sequence when adequate draft is not confirmed\u003c\/li\u003e\n  \u003cli\u003eDesigned for G7SC-1 Upflow\/Horizontal furnace applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on the G7SC-1 Upflow\/Horizontal furnace as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Before servicing, shut off power to the furnace at the disconnect switch and close the manual gas shutoff valve. Inspect the rubber pressure hose and port for cracks or blockages before connecting the new switch, as a faulty hose is a common cause of nuisance pressure switch trips. Refer to the furnace wiring diagram and follow all applicable local codes during replacement.\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\u003ePressure Setpoint\u003c\/strong\u003e: 0.60 inches WC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Configuration\u003c\/strong\u003e: SPST (Single-Pole Single-Throw)\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: 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: 632493R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51283931267378,"sku":"632493R","price":36.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277950.jpg?v=1781063502","url":"https:\/\/voomisupply.com\/products\/westinghouse-632493r-furnace-pressure-switch-0-60-in-wc-spst","provider":"Voomi Supply","version":"1.0","type":"link"}
