{"product_id":"773-074","title":"773-074","description":"Ensure your high-efficiency heating system operates safely and effectively with this premium two-stage air pressure switch. Designed for dual-stage gas furnaces and HVAC units, this air proving switch serves as a vital safety mechanism by monitoring the pressure generated by the inducer motor. It is calibrated to detect specific pressure differentials of -0.10\" WC and -0.97\" WC, ensuring that the combustion process only begins when proper airflow is confirmed and the exhaust vent is clear. A common replacement part for furnaces experiencing ignition failure or intermittent cycling, this pressure sensor helps maintain peak performance and prevents hazardous operating conditions. Built with high-quality materials for long-lasting reliability, it is an essential component for residential forced-air systems requiring a precise dual-action vacuum switch.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard HVAC Component\u003cbr\u003e\nApplication: Used in two-stage gas furnaces and high-efficiency HVAC systems to monitor draft inducer pressure and ensure safe venting.\u003cbr\u003e\nSpecifications: Dual-stage calibration: -0.10\" WC and -0.97\" WC; Function: Air proving \/ Safety cutout; Configuration: Two-stage pressure sensing.","brand":"BCFurnace","offers":[{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.10\" WC \/ -0.97\" WC \/ 773-074","offer_id":47251218399517,"sku":null,"price":80.26,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.10\" WC \/ -0.97\" WC \/ 0130F00479","offer_id":47251218432285,"sku":null,"price":80.26,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.10\" WC \/ -0.97\" WC \/ 9371VO-HD-0138","offer_id":47251218465053,"sku":null,"price":80.26,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/98284c1810924762bf84fa0d247a1dd8.webp?v=1773957845","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-074","provider":"BCFurnace","version":"1.0","type":"link"}
