{"product_id":"773-396","title":"773-396","description":"This premium air pressure switch is a vital safety component designed for high-efficiency furnaces and HVAC systems. Functioning as an air proving switch, it monitors the vacuum pressure generated by the inducer motor to ensure that combustion gases are being properly vented before allowing the heating cycle to begin. Rated at a precise 1.0\" WC (Water Column), this switch prevents the system from igniting under unsafe conditions, such as a blocked flue or a failing vent motor. It is an essential replacement part for restoring the reliable and safe operation of residential and light commercial heating equipment.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard HVAC component\u003cbr\u003e\nApplication: Commonly used in gas-fired furnaces, packaged heat pumps, and air handling units to verify inducer motor performance and airflow safety.\u003cbr\u003e\nSpecifications: Pressure Rating: 1.0\" WC (Water Column); Type: Air Proving Safety Switch; Application: Combustion environment monitoring.","brand":"BCFurnace","offers":[{"title":"YORK\/ETC PRESSURE SWITCH, 1.0\" WC \/ 773-396","offer_id":50572854427933,"sku":null,"price":114.06,"currency_code":"CAD","in_stock":true},{"title":"YORK\/ETC PRESSURE SWITCH, 1.0\" WC \/ 02435780000","offer_id":50572854493469,"sku":null,"price":114.06,"currency_code":"CAD","in_stock":true},{"title":"YORK\/ETC PRESSURE SWITCH, 1.0\" WC \/ S1-02435780000","offer_id":50572854460701,"sku":null,"price":114.06,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/1efeb9a7e40840dba13261b2b0a12e59.webp?v=1773966476","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-396","provider":"BCFurnace","version":"1.0","type":"link"}
