{"product_id":"773-286","title":"773-286","description":"Ensure the safety and efficiency of your heating system with this premium two-stage air pressure switch. Designed for modern high-efficiency gas furnaces, this air-proving switch monitors the vacuum pressure generated by the inducer motor to verify proper combustion airflow and venting. By sensing specific pressure thresholds, it acts as a critical safety limit, preventing the furnace from igniting if it detects dangerous venting conditions or mechanical failures. This dual-stage component is engineered for HVAC systems that operate at multiple speeds, providing precise monitoring for both low-heat and high-heat cycles. If your furnace is experiencing ignition lockout, frequent cycling, or failing to start, replacing a faulty pressure switch can restore reliable heating performance and ensure your home remains safe.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Small \/ Compact\u003cbr\u003e\nApplication: Used in residential two-stage gas furnaces and HVAC units to monitor inducer fan performance and ensure safe exhaust venting before allowing the ignition sequence to proceed.\u003cbr\u003e\nSpecifications: Two-stage operation; Low-stage set point: -0.08\" WC; High-stage set point: -1.49\" WC; Diaphragm-actuated safety sensor; Designed for multi-speed induction systems.","brand":"BCFurnace","offers":[{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.08\" WC \/ -1.49\" WC \/ 773-286","offer_id":47251946471709,"sku":null,"price":77.1,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.08\" WC \/ -1.49\" WC \/ 0130F00447","offer_id":47251946504477,"sku":null,"price":77.1,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/ed1b7cb3351a416f956d83b7f8819729.webp?v=1773967398","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-286","provider":"BCFurnace","version":"1.0","type":"link"}
