{"product_id":"773-016","title":"773-016","description":"This high-quality replacement pressure switch is designed for Lennox gas furnaces and HVAC heating systems. As a critical air proving component, it monitors the negative pressure created by the draft inducer motor to ensure proper venting of exhaust gases before ignition. Operating at a set point of -0.95\" WC (Water Column), this vacuum switch acts as a vital safety lockout, preventing the furnace from operating if it detects inadequate airflow, a failing inducer motor, or a blocked vent. If your heating system is experiencing startup failures or intermittent shut-offs, replacing the air pressure switch can restore safe and efficient operation. Engineered for durability and precision, this switch ensures your HVAC system maintains optimal combustion and indoor air safety.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard\u003cbr\u003e\nApplication: Used in residential gas furnaces and HVAC units to prove airflow and ensure combustion safety.\u003cbr\u003e\nSpecifications: Pressure Setting: -0.95\" WC (Water Column); Sensing Type: Negative Pressure\/Vacuum; Application: Air Proving and Safety Cut-off.","brand":"BCFurnace","offers":[{"title":"LENNOX PRESSURE SWITCH -0.95\" WC \/ 773-016","offer_id":47251045351709,"sku":null,"price":122.81,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.95\" WC \/ 101256-03","offer_id":47251045450013,"sku":null,"price":122.81,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.95\" WC \/ 51W91","offer_id":47251045417245,"sku":null,"price":122.81,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.95\" WC \/ 56M05","offer_id":47251045384477,"sku":null,"price":122.81,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.95\" WC \/ 56M0501","offer_id":47251045482781,"sku":null,"price":122.81,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/0bbef84478a640b588fa425b65335db6.webp?v=1773957404","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-016","provider":"BCFurnace","version":"1.0","type":"link"}
