{"product_id":"773-078","title":"773-078","description":"This premium two-stage air pressure switch is a vital safety component designed for high-efficiency residential gas furnaces. As an essential air proving sensor, it monitors the internal vacuum pressure generated by the inducer motor to ensure proper venting of combustion gases before the heating cycle begins. Specifically engineered for dual-stage heating systems, it features two distinct set points to manage airflow requirements for both low-heat and high-heat operations. Replacing a faulty pressure switch can resolve common furnace issues such as ignition failure, short cycling, or error codes related to venting. This durable replacement part ensures your HVAC system operates safely, efficiently, and reliably throughout the heating season.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Compact\u003cbr\u003e\nApplication: Used in high-efficiency two-stage gas furnaces and HVAC systems to verify proper inducer motor draft and venting safety.\u003cbr\u003e\nSpecifications: Dual-stage calibration; Low-stage set point: -0.67\" WC; High-stage set point: -1.25\" WC; Type: Negative pressure\/vacuum sensing.","brand":"BCFurnace","offers":[{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.67\" WC \/ -1.25\" WC \/ 773-078","offer_id":47251237175581,"sku":null,"price":85.94,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.67\" WC \/ -1.25\" WC \/ 0130F00443","offer_id":47251237208349,"sku":null,"price":85.94,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.67\" WC \/ -1.25\" WC \/ 9375VD-0050","offer_id":47251237241117,"sku":null,"price":85.94,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/0ba1d650a0344cba9ae59c4df111d657.webp?v=1773959907","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-078","provider":"BCFurnace","version":"1.0","type":"link"}
