{"product_id":"773-323","title":"773-323","description":"This high-precision air pressure switch is a critical safety component designed for residential gas furnaces and HVAC systems. Also known as an air proving switch, it monitors the pressure generated by the draft inducer motor to ensure the venting system is clear and operating at peak efficiency before allowing the heating cycle to proceed. With a factory-calibrated set point of 0.35\" WC (Water Column), this switch prevents the furnace from operating under unsafe conditions, such as a blocked flue or mechanical failure. Replacing a faulty pressure switch can resolve common heating issues, including ignition failure and system cycling problems, ensuring your home remains warm and safe during the colder months.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard\u003cbr\u003e\nApplication: Used in forced-air gas furnaces and HVAC heating units to prove combustion air flow and monitor inducer motor performance.\u003cbr\u003e\nSpecifications: Pressure Setting: 0.35\" WC (Water Column); Function: Air proving and safety interlocking; Connection Type: Standard terminal and hose ports.","brand":"BCFurnace","offers":[{"title":"PRESSURE SWITCH 0.35\" WC \/ 773-323","offer_id":49643004494109,"sku":null,"price":100.86,"currency_code":"CAD","in_stock":true},{"title":"PRESSURE SWITCH 0.35\" WC \/ 1011739","offer_id":49643004526877,"sku":null,"price":100.86,"currency_code":"CAD","in_stock":true},{"title":"PRESSURE SWITCH 0.35\" WC \/ 1193107","offer_id":49643004559645,"sku":null,"price":100.86,"currency_code":"CAD","in_stock":true},{"title":"PRESSURE SWITCH 0.35\" WC \/ HQ1011739TR","offer_id":49896000422173,"sku":null,"price":100.86,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/8e382c36c125457d88fdcba7e27bac16.webp?v=1773957361","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-323","provider":"BCFurnace","version":"1.0","type":"link"}
