{"product_id":"773-412","title":"773-412","description":"This high-quality furnace pressure switch with hose is a critical safety component designed for modern gas furnace heating systems. As an air proving switch, it monitors the negative pressure created by the inducer fan motor to ensure proper venting of combustion gases before ignition occurs. With a precise set point of -0.27\" WC (Water Column), this switch prevents the furnace from operating if a venting obstruction or motor failure is detected, protecting your home from potential safety hazards. If your heating system is failing to ignite or displaying error codes related to the draft inducer, a faulty pressure switch may be the cause. This replacement kit includes the necessary flexible tubing for a secure and reliable connection, ensuring your HVAC system returns to peak efficiency and safety.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Used in residential gas furnaces and HVAC systems to monitor inducer motor draft and ensure safe combustion venting.\u003cbr\u003e\nSpecifications: Pressure Rating: -0.27\" WC (Water Column); Includes vacuum hose\/tubing; Air proving safety functionality.","brand":"BCFurnace","offers":[{"title":"Pressure Switch with Hose, -0.27\" WC PF \/ 773-412","offer_id":50572959449373,"sku":null,"price":48.63,"currency_code":"CAD","in_stock":true},{"title":"Pressure Switch with Hose, -0.27\" WC PF \/ 1192373","offer_id":50572959482141,"sku":null,"price":48.63,"currency_code":"CAD","in_stock":true},{"title":"Pressure Switch with Hose, -0.27\" WC PF \/ ICP1192373","offer_id":50572960039197,"sku":null,"price":48.63,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/7ecd307079da4a5bb918bd1318f32992.webp?v=1773966184","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-412","provider":"BCFurnace","version":"1.0","type":"link"}
