{"product_id":"773-089","title":"773-089","description":"This high-quality two-stage air pressure switch is a critical safety component designed for high-efficiency gas furnaces and HVAC systems. As an essential air proving switch, it monitors the vacuum pressure created by the draft inducer motor to ensure proper venting before allowing the heating cycle to begin. This dual-stage component is calibrated to detect specific pressure differentials required for both low-fire and high-fire operation, helping to maintain optimal combustion efficiency. If your furnace is failing to ignite or experiencing intermittent shut-offs due to pressure switch lockout codes, this replacement part provides a reliable solution to restore your heating system's performance. Engineered for precision and durability, it acts as a fail-safe to prevent the furnace from operating under unsafe venting conditions or obstructed flue pipes.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Used in multi-stage high-efficiency residential gas furnaces and HVAC systems to verify airflow and inducer motor operation during the ignition sequence.\u003cbr\u003e\nSpecifications: Two-stage operation; Set points: -0.35\" WC (Water Column) and -0.50\" WC; Function: Air Proving \/ Differential Pressure Sensing.","brand":"BCFurnace","offers":[{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.35\" WC \/ -0.50\" WC \/ 773-089","offer_id":47251254575389,"sku":null,"price":108.14,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.35\" WC \/ -0.50\" WC \/ 0130F00722","offer_id":47251254608157,"sku":null,"price":108.14,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.35\" WC \/ -0.50\" WC \/ 0130F00722S","offer_id":47251254640925,"sku":null,"price":108.14,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.35\" WC \/ -0.50\" WC \/ 9375VD-0326","offer_id":47251254673693,"sku":null,"price":108.14,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/5d8f2f4817a3417f94046c6520c23a2a.webp?v=1773957965","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-089","provider":"BCFurnace","version":"1.0","type":"link"}
