{"product_id":"773-014","title":"773-014","description":"The Lennox Pressure Switch (-1.00\" WC) is a vital safety component for residential gas furnaces and HVAC systems. Also known as an air-proving switch, this part monitors the negative pressure created by the draft inducer motor to ensure proper venting before the heating cycle begins. It acts as a fail-safe, preventing the furnace from igniting if it detects a blockage or a failure in the exhaust system. If your heating system is experiencing ignition issues or signaling a pressure fault, replacing the air pressure sensor can restore reliable operation. This high-quality component is designed for precise vacuum detection, ensuring your home stays warm and safe throughout the winter.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Compact\u003cbr\u003e\nApplication: Gas furnace safety circuits, draft inducer motor monitoring, and residential HVAC system maintenance.\u003cbr\u003e\nSpecifications: Pressure Rating: -1.00\" WC (Water Column); Function: Air proving and safety shut-off; Type: Negative pressure sensing.","brand":"BCFurnace","offers":[{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 773-014","offer_id":47251050791197,"sku":null,"price":109.04,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 100658-01","offer_id":47251050856733,"sku":null,"price":109.04,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 101256-04","offer_id":47251050922269,"sku":null,"price":109.04,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 51W92","offer_id":47251050889501,"sku":null,"price":109.04,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 95M22","offer_id":47251050823965,"sku":null,"price":109.04,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/b49b618127fc40029b9dbc36f4878b4d.webp?v=1773957390","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-014","provider":"BCFurnace","version":"1.0","type":"link"}
