{"product_id":"773-383","title":"773-383","description":"The Dual Pressure Switch (0.55\" WC \/ 1.30\" WC) is a critical safety component designed for high-efficiency residential gas furnaces. As an essential air proving switch, it monitors the pressure generated by the inducer motor to ensure the exhaust venting system is functioning correctly before allowing the heating cycle to proceed. Specifically engineered for two-stage heating systems, this dual-function switch detects specific pressure thresholds to manage different performance levels. If your furnace is experiencing ignition failure, frequent cycling, or system lockouts, a faulty air pressure switch may be the cause. This replacement part ensures reliable operation, safe venting, and optimal energy efficiency for your HVAC system.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Compact\u003cbr\u003e\nApplication: Used in residential high-efficiency two-stage gas furnaces and HVAC systems to verify proper airflow and inducer motor operation.\u003cbr\u003e\nSpecifications: Dual-stage calibration with set points at 0.55 inches Water Column (WC) and 1.30 inches Water Column (WC); designed for air proving and safety lockout circuits.","brand":"BCFurnace","offers":[{"title":"YORK\/ETC DUAL PRESSURE SWITCH 0.55\" WC \/ 1.30\" WC \/ 773-383","offer_id":50572556501277,"sku":null,"price":285.7,"currency_code":"CAD","in_stock":true},{"title":"YORK\/ETC DUAL PRESSURE SWITCH 0.55\" WC \/ 1.30\" WC \/ 02435269000","offer_id":50572564103453,"sku":null,"price":285.7,"currency_code":"CAD","in_stock":true},{"title":"YORK\/ETC DUAL PRESSURE SWITCH 0.55\" WC \/ 1.30\" WC \/ S1-02435269000","offer_id":50572556534045,"sku":null,"price":285.7,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/921bb9e4f8ee48c891160c1c5195fc78.webp?v=1773967993","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-383","provider":"BCFurnace","version":"1.0","type":"link"}
