{"product_id":"773-010","title":"773-010","description":"This dual-stage air pressure switch is a vital safety component designed for high-efficiency residential gas furnaces. Engineered to monitor the pressure differential created by the draft inducer motor, this switch ensures that the heating system operates safely by verifying proper airflow and venting before allowing the ignition process to begin. As a two-stage air proving switch, it features precise calibrated setpoints of 0.22\" WC and 0.43\" WC, allowing the HVAC system to modulate correctly between low-fire and high-fire heating cycles. Replacing a faulty or sticking pressure switch is essential for resolving furnace lockout issues, preventing hazardous venting conditions, and maintaining optimal combustion efficiency in multi-stage furnaces. This durable component is a reliable solution for restoring the safety and performance of your home heating equipment.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard furnace component\u003cbr\u003e\nDimensions: unknown × unknown × unknown\u003cbr\u003e\nApplication: Used in residential gas furnaces and HVAC systems with two-stage heating cycles to monitor inducer motor pressure and ensure safe combustion airflow.\u003cbr\u003e\nSpecifications: Two-stage operation; Low-stage setpoint: 0.22\" WC; High-stage setpoint: 0.43\" WC; Differential pressure sensing; Snap-action electrical contacts.","brand":"BCFurnace","offers":[{"title":"CARRIER PRESSURE SWITCH 2-STG 0.22\" WC \/ 0.43\" WC \/ 773-010","offer_id":47251008356637,"sku":null,"price":1018.66,"currency_code":"CAD","in_stock":true},{"title":"CARRIER PRESSURE SWITCH 2-STG 0.22\" WC \/ 0.43\" WC \/ HK06WC077","offer_id":47251008389405,"sku":null,"price":1018.66,"currency_code":"CAD","in_stock":true},{"title":"CARRIER PRESSURE SWITCH 2-STG 0.22\" WC \/ 0.43\" WC \/ HK06WC082","offer_id":47251008422173,"sku":null,"price":1018.66,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/1ddcfcdde9684e1e95ef7a979d425697.webp?v=1773957261","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-010","provider":"BCFurnace","version":"1.0","type":"link"}
