{"product_id":"773-263","title":"773-263","description":"This premium 1.0\" WC Air Pressure Switch is a critical safety component designed for residential gas furnaces and forced-air heating systems. As an essential air proving switch, it monitors the pressure differential created by the draft inducer motor to ensure that combustion gases are being safely and effectively exhausted through the vent pipe. If the system detects that the pressure has not reached the required 1.0-inch water column threshold, the switch prevents the furnace from igniting, protecting the household from potential flue gas leaks. This high-precision sensor is a common solution for resolving furnace ignition failures, pressure switch lockout errors, and intermittent heating issues. Built for reliability and long-lasting performance, it ensures your HVAC equipment maintains peak safety and efficiency during the heating season.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Compact\u003cbr\u003e\nApplication: Residential gas furnaces, HVAC heating systems, and forced air combustion units.\u003cbr\u003e\nSpecifications: 1.0\" Water Column (WC) set point, air proving safety interlock, diaphragm-actuated.","brand":"BCFurnace","offers":[{"title":"PRESSURE SWITCH 1.0\" WC \/ 773-263","offer_id":47251442041117,"sku":null,"price":116.26,"currency_code":"CAD","in_stock":true},{"title":"PRESSURE SWITCH 1.0\" WC \/ SWT03926","offer_id":47251442073885,"sku":null,"price":116.26,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/21b000540b57429fbea3cd12f0ff9298.webp?v=1773960717","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-263","provider":"BCFurnace","version":"1.0","type":"link"}
