{"product_id":"773-141","title":"773-141","description":"This high-quality replacement air pressure switch is a critical safety component for residential gas furnaces and heating systems. Specifically calibrated to a -0.68\" WC (Water Column) set point, this air proving switch monitors the draft created by the inducer fan to ensure combustion gases are being safely exhausted from the heat exchanger. If the venting system is obstructed or the motor fails to move enough air, this switch prevents the ignition cycle from starting, protecting your home from potential hazards. Replacing a faulty or failing pressure switch can resolve common furnace issues such as failed ignition, frequent cycling, or error codes related to airflow. Designed for precision and reliability, this component is essential for maintaining the efficiency and safety of your HVAC equipment.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard HVAC component\u003cbr\u003e\nApplication: Residential gas furnaces, forced-air heating systems, and HVAC inducer blower assemblies.\u003cbr\u003e\nSpecifications: Pressure Setting: -0.68\" WC (Water Column); Function: Air Proving\/Safety Interlock; Type: Negative Pressure Sensor.","brand":"BCFurnace","offers":[{"title":"LENNOX PRESSURE SWITCH -0.68\" WC \/ 773-141","offer_id":47251313197341,"sku":null,"price":106.8,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.68\" WC \/ 103018-05","offer_id":47251313328413,"sku":null,"price":106.8,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.68\" WC \/ 10301805","offer_id":49428870267165,"sku":null,"price":106.8,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.68\" WC \/ 103247-05","offer_id":47251313295645,"sku":null,"price":106.8,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.68\" WC \/ 10324705","offer_id":49428872036637,"sku":null,"price":106.8,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.68\" WC \/ 74W61","offer_id":47251313230109,"sku":null,"price":106.8,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.68\" WC \/ 74W6101","offer_id":49428876329245,"sku":null,"price":106.8,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.68\" WC \/ 80W53","offer_id":47251313262877,"sku":null,"price":106.8,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH -0.68\" WC \/ 80W5301","offer_id":49428876820765,"sku":null,"price":106.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/3038da24c40b4798b4f3970ea4155a46.webp?v=1773960866","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-141","provider":"BCFurnace","version":"1.0","type":"link"}
