{"product_id":"773-051","title":"773-051","description":"This premium 2-stage air pressure switch is a vital safety component for high-efficiency gas furnaces. Designed as an air-proving switch, it monitors the differential pressure generated by the draft inducer motor to ensure that combustion gases are being safely exhausted before allowing the furnace to ignite. Featuring dual-stage calibration at 1.60\" WC and 0.81\" WC, it is specifically engineered for two-stage heating systems, ensuring precise performance during both low-fire and high-fire cycles. If your heating system is experiencing ignition failure, intermittent cycling, or triggering pressure switch error codes, this replacement part is essential for restoring safe and efficient HVAC operation.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard HVAC Component\u003cbr\u003e\nApplication: High-efficiency two-stage gas furnaces and residential heating systems requiring air-proving safety controls.\u003cbr\u003e\nSpecifications: Dual-stage sensing; High-stage setpoint: 1.60\" WC; Low-stage setpoint: 0.81\" WC; Air-proving functionality; Designed for induced-draft combustion systems.","brand":"BCFurnace","offers":[{"title":"PRESSURE SWITCH 2-STG 1.60\" WC \/ 0.81\" WC \/ 773-051","offer_id":47251032604957,"sku":null,"price":146.96,"currency_code":"CAD","in_stock":true},{"title":"PRESSURE SWITCH 2-STG 1.60\" WC \/ 0.81\" WC \/ 319893-401","offer_id":47251032670493,"sku":null,"price":146.96,"currency_code":"CAD","in_stock":true},{"title":"PRESSURE SWITCH 2-STG 1.60\" WC \/ 0.81\" WC \/ HK06MB023","offer_id":47251032703261,"sku":null,"price":146.96,"currency_code":"CAD","in_stock":true},{"title":"PRESSURE SWITCH 2-STG 1.60\" WC \/ 0.81\" WC \/ HK06NB023","offer_id":47251032637725,"sku":null,"price":146.96,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/8b7008f461d94366b3c20dbc8ae844f1.webp?v=1773957392","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-051","provider":"BCFurnace","version":"1.0","type":"link"}
