{"product_id":"773-098","title":"773-098","description":"This professional-grade air pressure switch is a vital safety component for residential and commercial gas furnaces. Designed as an air-proving sensor, it monitors the negative pressure generated by the draft inducer motor to ensure proper venting and airflow before the ignition process begins. By accurately sensing a 1.29\" WC threshold, this switch prevents the furnace from operating under unsafe conditions, such as a blocked flue or a failing inducer fan. A high-quality replacement part, it is essential for restoring the reliability and safety of your HVAC system's combustion cycle. Durable and precision-engineered, this switch helps maintain optimal heating performance and efficiency throughout the winter season.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard HVAC Component\u003cbr\u003e\nApplication: Gas furnaces, air handlers, and HVAC heating systems requiring an air-proving safety sensor for induction motor verification.\u003cbr\u003e\nSpecifications: 1.29\" WC (Water Column) pressure rating, air-proving functionality, factory-calibrated setpoint.","brand":"BCFurnace","offers":[{"title":"TRANE PRESSURE SWITCH 1.29\" WC \/ 773-098","offer_id":47251255460125,"sku":null,"price":124.9,"currency_code":"CAD","in_stock":true},{"title":"TRANE PRESSURE SWITCH 1.29\" WC \/ SWT 02965","offer_id":47251255558429,"sku":null,"price":124.9,"currency_code":"CAD","in_stock":true},{"title":"TRANE PRESSURE SWITCH 1.29\" WC \/ SWT02965","offer_id":47251255492893,"sku":null,"price":124.9,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/2ca95eef4f2047a2a1f922af841f5878.webp?v=1773958005","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-098","provider":"BCFurnace","version":"1.0","type":"link"}
