{"product_id":"773-242","title":"773-242","description":"This professional-grade 0.35\" WC Air Pressure Switch is a crucial safety component designed for heating systems and gas furnaces. Functioning as an air proving switch, it monitors the pressure within the draft inducer motor to ensure proper ventilation and exhaust flow before the ignition process begins. By detecting the specific pressure threshold of 0.35 inches of water column, this switch prevents the furnace from operating under unsafe conditions, such as a blocked flue or a failing inducer motor. This reliable sensor is essential for maintaining the efficiency and safety of your HVAC unit, providing peace of mind and protecting your equipment from potential damage during the heating season.\u003cbr\u003e\nType: Air Pressure Switch \/ Air Proving Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Residential gas furnaces, HVAC heating systems, and draft inducer assemblies.\u003cbr\u003e\nSpecifications: Pressure Setting: 0.35\" WC (Water Column); Function: Safety Interlock and Airflow Proving","brand":"BCFurnace","offers":[{"title":"PRESSURE SWITCH 0.35\" WC \/ 773-242","offer_id":47251823690013,"sku":null,"price":206.19,"currency_code":"CAD","in_stock":true},{"title":"PRESSURE SWITCH 0.35\" WC \/ 42-24194-01","offer_id":47251823722781,"sku":null,"price":206.19,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/2834547db33742d88e7656034a40cbec.webp?v=1773967371","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-242","provider":"BCFurnace","version":"1.0","type":"link"}
