{"product_id":"773-347","title":"773-347","description":"This high-performance dual-port air pressure switch is a vital safety component designed for Lennox gas furnaces and residential HVAC systems. Functioning as an air proving switch, it monitors the draft inducer motor to ensure proper airflow and venting are established before the ignition sequence begins. This prevents the furnace from operating under unsafe conditions, such as blocked vents or inducer motor failure. Featuring a precise 2.50\" WC (Water Column) set point and a reliable SPST (Single Pole Single Throw) contact configuration, this component is the ideal solution for repairing heating systems experiencing ignition failure, frequent cycling, or pressure switch lockout codes. Built for long-term durability, it ensures your heating equipment operates efficiently and safely throughout the winter months.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard HVAC control component\u003cbr\u003e\nApplication: Residential gas furnaces and high-efficiency heating systems requiring draft inducer airflow monitoring.\u003cbr\u003e\nSpecifications: Switch Type: SPST (Single Pole Single Throw); Port Configuration: Dual Port; Pressure Rating: 2.50 inches WC (Water Column); Function: Air Proving\/Safety Interlock.","brand":"BCFurnace","offers":[{"title":"LENNOX PRESSURE SWITCH DUAL PORT 2.50\" WC SPST \/ 773-347","offer_id":50568394211613,"sku":null,"price":647.08,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH DUAL PORT 2.50\" WC SPST \/ 58H30","offer_id":50568394244381,"sku":null,"price":647.08,"currency_code":"CAD","in_stock":true},{"title":"LENNOX PRESSURE SWITCH DUAL PORT 2.50\" WC SPST \/ 58H3001","offer_id":50568394277149,"sku":null,"price":647.08,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/c2d7037da2484c3ea17393e7333e2cee.webp?v=1773965927","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-347","provider":"BCFurnace","version":"1.0","type":"link"}
