{"product_id":"773-182","title":"773-182","description":"This premium air pressure switch is a vital safety component designed for heating systems and furnaces. Functioning as an air-proving switch, it monitors the negative pressure generated by the inducer motor to ensure the combustion chamber is venting toxic flue gases correctly. If the pressure levels are incorrect, the switch prevents the ignition sequence from proceeding, protecting your home or facility from potential hazards. Ideal for HVAC repair and maintenance, this component is engineered to restore the proper operation of your heating unit when the original switch fails to close or stays stuck open. Its precise calibration ensures your furnace or unit heater operates at peak efficiency and remains compliant with safety standards.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Compact\u003cbr\u003e\nApplication: Used in high-efficiency forced-air furnaces, unit heaters, and commercial HVAC equipment to verify proper venting and inducer motor performance.\u003cbr\u003e\nSpecifications: Set point: -1.00\" WC (Water Column); functions as a vacuum-sensing safety interlock for gas-fired heating appliances.","brand":"BCFurnace","offers":[{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 773-182","offer_id":50509875675421,"sku":null,"price":142.4,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 34M77","offer_id":50509875773725,"sku":null,"price":142.4,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 34M7701","offer_id":50509875872029,"sku":null,"price":142.4,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 60J54","offer_id":50509875740957,"sku":null,"price":142.4,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 60J5401","offer_id":50509875806493,"sku":null,"price":142.4,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 65289100","offer_id":50509875839261,"sku":null,"price":142.4,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 85K37","offer_id":50509875708189,"sku":null,"price":142.4,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -1.00\" WC \/ 85K3701","offer_id":50509875904797,"sku":null,"price":142.4,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/9852abaf78f140dbb17c7e64c3496154.webp?v=1773958834","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-182","provider":"BCFurnace","version":"1.0","type":"link"}
