{"product_id":"773-287","title":"773-287","description":"Ensure your heating system operates at peak safety and efficiency with this high-quality dual-stage air pressure switch. Specifically engineered for high-efficiency gas furnaces, this air-proving switch monitors the pressure generated by the inducer motor to verify proper venting before the ignition process begins. By detecting precise pressure differentials at two distinct stages, it prevents the furnace from operating under unsafe conditions, such as a blocked flue or a failing draft inducer. This reliable component is an essential replacement for HVAC systems experiencing startup issues, frequent cycling, or safety lockout codes related to airflow verification.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nApplication: High-efficiency two-stage gas furnaces and residential HVAC heating systems requiring air-proving safety verification.\u003cbr\u003e\nSpecifications: Dual-stage configuration; Setpoint A: -0.10\" WC; Setpoint B: -0.75\" WC; Function: Air proving and combustion safety.","brand":"BCFurnace","offers":[{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.10\" WC \/ -0.75\" WC \/ 773-287","offer_id":47251966656797,"sku":null,"price":68.86,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.10\" WC \/ -0.75\" WC \/ 0130F00469","offer_id":47251966689565,"sku":null,"price":68.86,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/064174eb333f48fba9b2b03c591abfe7.webp?v=1773959714","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-287","provider":"BCFurnace","version":"1.0","type":"link"}
