{"product_id":"021-750","title":"021-750","description":"Ensure your heating system operates safely and efficiently with this high-quality replacement flame sensor rod. Designed for use in gas furnaces and HVAC units, this flame sensor plays a critical role in your system’s ignition sequence. It monitors the presence of a flame once the burner ignites; if a flame is not detected, the sensor sends a signal to the control board to shut off the gas valve, preventing hazardous gas buildup. Common symptoms of a failing flame sensor include the furnace starting and then immediately shutting down or the burner failing to stay lit. This durable sensor features a 1-inch detection rod and a total length of 3 1\/4 inches, providing a reliable connection and precise flame monitoring for residential and commercial heating equipment.\u003cbr\u003e\nType: Flame Sensor Rod\u003cbr\u003e\nSize: Small\u003cbr\u003e\nDimensions: 3.25 inches\u003cbr\u003e\nApplication: Commonly used in gas-fired furnaces, HVAC systems, and heating units to detect burner flame presence and ensure safety during the ignition cycle.\u003cbr\u003e\nSpecifications: 1-inch sensor tip with a 3 1\/4-inch total length including the insulator and mounting bracket.","brand":"BCFurnace","offers":[{"title":"Flame Sensor, 3 1\/4\" Total Length, 1\" Sensor \/ 021-750","offer_id":50341969592605,"sku":null,"price":107.62,"currency_code":"CAD","in_stock":true},{"title":"Flame Sensor, 3 1\/4\" Total Length, 1\" Sensor \/ SEN00007","offer_id":50341969625373,"sku":null,"price":107.62,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/a13761506b3646a78fe45b9a37258fc0.webp?v=1773966089","url":"https:\/\/bcfurnace.myshopify.com\/products\/021-750","provider":"BCFurnace","version":"1.0","type":"link"}
