{"product_id":"773-034","title":"773-034","description":"The Lennox Pressure Switch 0.8\" WC is a vital safety component engineered for residential gas furnaces and high-efficiency HVAC systems. Functioning as an air-proving switch, it monitors the draft pressure created by the inducer blower motor to ensure combustion gases are being properly vented. If the system detects insufficient airflow or a blocked vent, this vacuum-actuated switch prevents the furnace from igniting, protecting your home from potential hazards. Calibrated to a precise 0.8-inch water column set point, this replacement pressure switch is essential for troubleshooting furnace ignition failures, pressure switch stuck open errors, and intermittent heating issues. It is a reliable solution for maintaining the safety and efficiency of your heating equipment.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Compact\u003cbr\u003e\nApplication: Used in residential gas furnaces and HVAC units to monitor inducer motor draft and ensure safe flue gas ventilation.\u003cbr\u003e\nSpecifications: Pressure Setting: 0.8\" WC (Water Column); Type: Air Proving\/Vacuum Switch; Application: Furnace Safety Control","brand":"BCFurnace","offers":[{"title":"LENNOX PRESSURE SWITCH 0.8\" WC \/ 773-034","offer_id":47251069272349,"sku":null,"price":289.54,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 0.8\" WC \/ 60L03","offer_id":47251069305117,"sku":null,"price":289.54,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH 0.8\" WC \/ 60L0301","offer_id":47251069337885,"sku":null,"price":289.54,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/8f0ac5f1dcab4aed914cc9ad6b4cb425.webp?v=1773957460","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-034","provider":"BCFurnace","version":"1.0","type":"link"}
