{"product_id":"773-149","title":"773-149","description":"This high-precision Air Pressure Switch is a vital safety component designed for modern HVAC systems and gas-fired furnaces. Acting as an air proving switch, it monitors the pressure differential created by the inducer blower motor to ensure proper combustion airflow and venting. Rated at 0.59\" WC (Water Column), this switch prevents the heating cycle from proceeding if it detects a blockage in the flue or a failure in the venting system, protecting your home from improper exhaust. If your furnace is experiencing ignition failure or shutting down prematurely, this replacement pressure switch provides the reliable sensing needed to restore safe and efficient operation. Engineered for durability, it is a common fix for HVAC units requiring precise pressure monitoring.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard\u003cbr\u003e\nApplication: Used in residential gas furnaces, HVAC heating units, and inducer blower assemblies to verify proper venting and airflow before ignition.\u003cbr\u003e\nSpecifications: Pressure Setting: 0.59\" WC; Function: Air Proving\/Safety Interlock","brand":"BCFurnace","offers":[{"title":"ICP PRESSURE SWITCH 0.59\" WC \/ 773-149","offer_id":47251326730525,"sku":null,"price":104.81,"currency_code":"CAD","in_stock":true},{"title":"ICP PRESSURE SWITCH 0.59\" WC \/ 1013529","offer_id":47251326763293,"sku":null,"price":104.81,"currency_code":"CAD","in_stock":true},{"title":"ICP PRESSURE SWITCH 0.59\" WC \/ 1174276","offer_id":47251326796061,"sku":null,"price":104.81,"currency_code":"CAD","in_stock":true},{"title":"ICP PRESSURE SWITCH 0.59\" WC \/ IS20213-5216","offer_id":47259048870173,"sku":null,"price":104.81,"currency_code":"CAD","in_stock":true},{"title":"ICP PRESSURE SWITCH 0.59\" WC \/ IS202135216","offer_id":47251326861597,"sku":null,"price":104.81,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/7382d83f51dd459aac6218a725954247.webp?v=1773958217","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-149","provider":"BCFurnace","version":"1.0","type":"link"}
