Pressure switches monitor the negative pressure created by the inducer motor to verify safe venting conditions before allowing the burners to fire. This switch is a safety-critical component in the furnace control sequence and is typically replaced by a licensed HVAC technician during a no-heat diagnosis or scheduled maintenance. Its dual setpoint design corresponds to the two firing stages of a 2-stage furnace, ensuring each stage is verified independently before ignition is permitted.\u003c\/p\u003e\n\u003cp\u003eThe 632523 is specified for use on MGC2 2-stage condensing and non-condensing gas furnaces. This makes it applicable to both standard-efficiency and high-efficiency residential furnace configurations within that product family. Installers working on 2-stage systems should confirm whether the failed switch is the high-stage or low-stage side, as this unit carries both setpoints in a single assembly, simplifying the replacement process on compatible MGC2 platform equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual setpoint design: 0.85 inches WC and 0.55 inches WC for 2-stage operation\u003c\/li\u003e\n  \u003cli\u003eCompatible with both condensing and non-condensing MGC2 furnace configurations\u003c\/li\u003e\n  \u003cli\u003eSafety-critical component that prevents ignition without confirmed inducer airflow\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement for straightforward field swap-out\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 gas furnaces as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePressure switch replacement is a licensed HVAC technician task. Always shut down the furnace and disconnect power at the disconnect switch before beginning any service on the control circuit. Inspect the rubber hose connecting the pressure switch to the inducer housing for cracks or blockages before replacing the switch itself, as a failed hose is a common cause of pressure switch faults. Verify the replacement switch setpoints match the original before reinstating power and testing furnace operation.\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\u003eSetpoint 1\u003c\/strong\u003e: 0.85 inches WC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetpoint 2\u003c\/strong\u003e: 0.55 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 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: 632523\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51283913408818,"sku":"632523","price":69.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277886.jpg?v=1781063108","url":"https:\/\/voomisupply.com\/products\/westinghouse-632523-furnace-pressure-switch-0-85-0-55-wc","provider":"Voomi Supply","version":"1.0","type":"link"}
