{"product_id":"773-245","title":"773-245","description":"This premium Triple Air Pressure Switch is a critical safety and performance component designed for high-efficiency gas furnaces and HVAC systems. As an essential air-proving switch, it monitors three distinct pressure thresholds—0.85\" WC, 1.00\" WC, and 0.40\" WC—to ensure the inducer fan motor is creating the necessary draft for safe combustion. If your heating system fails to ignite or shuts down prematurely, a faulty pressure switch may be the culprit, preventing the furnace from verifying that exhaust gases are being properly vented. This multi-stage switch is engineered to provide precise monitoring for variable-speed and multi-stage heating units, ensuring reliable operation and protecting against the buildup of dangerous combustion byproducts.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Used in residential high-efficiency gas furnaces, multi-stage heating systems, and forced-air HVAC units to verify proper airflow and venting before ignition.\u003cbr\u003e\nSpecifications: Triple-stage configuration; Pressure setpoints: 0.85\" WC, 1.00\" WC, and 0.40\" WC; Function: Air proving and safety lockout.","brand":"BCFurnace","offers":[{"title":"YORK PRESSURE SWITCH TRIPPLE 0.85\" WC \/ 1.00\" WC \/ 0.40\" WC \/ 773-245","offer_id":47251934970141,"sku":null,"price":308.19,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH TRIPPLE 0.85\" WC \/ 1.00\" WC \/ 0.40\" WC \/ 024-34681-000","offer_id":47251935068445,"sku":null,"price":308.19,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH TRIPPLE 0.85\" WC \/ 1.00\" WC \/ 0.40\" WC \/ 02434681000","offer_id":47251935101213,"sku":null,"price":308.19,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH TRIPPLE 0.85\" WC \/ 1.00\" WC \/ 0.40\" WC \/ S1-024-34681-000","offer_id":47251935035677,"sku":null,"price":308.19,"currency_code":"CAD","in_stock":true},{"title":"YORK PRESSURE SWITCH TRIPPLE 0.85\" WC \/ 1.00\" WC \/ 0.40\" WC \/ S1-02434681000","offer_id":47251935002909,"sku":null,"price":308.19,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/566a0d7bef7c4da787e26f36ad9bb0b1.webp?v=1773966750","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-245","provider":"BCFurnace","version":"1.0","type":"link"}
