{"product_id":"773-071","title":"773-071","description":"This high-performance air pressure switch is a critical safety component designed for modern gas furnaces and HVAC systems. As an essential air proving switch, it monitors the differential pressure created by the draft inducer motor to ensure flue gases are being safely exhausted from the combustion chamber. Calibrated to a precise 0.18\" WC (Water Column) set point, this sensor prevents the furnace from igniting if proper airflow is not detected, protecting your home from potential venting hazards. This durable replacement part is ideal for resolving issues where a heating system fails to complete its startup sequence or shuts down due to venting pressure errors.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard compact HVAC sensor\u003cbr\u003e\nApplication: Gas furnaces, forced-air heating systems, and draft inducer motor assemblies.\u003cbr\u003e\nSpecifications: Set Point: 0.18\" WC (Water Column); Type: Air proving\/safety vacuum switch; Function: Monitors inducer motor draft and venting pressure.","brand":"BCFurnace","offers":[{"title":"PRESSURE SWITCH 0.18\" WC \/ 773-071","offer_id":47251210273053,"sku":null,"price":136.44,"currency_code":"CAD","in_stock":true},{"title":"PRESSURE SWITCH 0.18\" WC \/ HK06WC075","offer_id":47251210371357,"sku":null,"price":136.44,"currency_code":"CAD","in_stock":true},{"title":"PRESSURE SWITCH 0.18\" WC \/ HK06WC085","offer_id":47251210338589,"sku":null,"price":136.44,"currency_code":"CAD","in_stock":true},{"title":"PRESSURE SWITCH 0.18\" WC \/ HK06WC097","offer_id":47251210305821,"sku":null,"price":136.44,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/003169c9335c4f688cdcdfcbb1112d0d.webp?v=1773967170","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-071","provider":"BCFurnace","version":"1.0","type":"link"}
