{"product_id":"120-684","title":"120-684","description":"Ensure the safety and reliability of your heating system with this high-performance furnace flame sensor rod. Designed to provide accurate flame detection for gas-fired furnaces, this component is essential for preventing unburned gas from accumulating in your HVAC unit. When the burner ignites, the sensor detects the flame's presence and sends a continuous signal to the furnace control board to keep the gas valve open. A faulty, cracked, or oxidized sensor is a leading cause of furnace short-cycling—where the heater starts and then immediately shuts down. This replacement part features durable, high-temperature resistant construction and a ceramic insulator to ensure long-lasting performance and consistent ignition throughout the heating season.\u003cbr\u003e\nType: Flame Sensor Rod\u003cbr\u003e\nSize: Small\u003cbr\u003e\nDimensions: Standard furnace sensor length\u003cbr\u003e\nApplication: Compatible with residential and commercial gas furnaces, forced air heating systems, and central HVAC units that utilize electronic ignition and flame rectification for safety.\u003cbr\u003e\nSpecifications: High-temperature resistant metal alloy rod, electrical grade ceramic insulation, and standard offset terminal for secure wiring connection.","brand":"BCFurnace","offers":[{"title":"YORK\/ETC FLAME SENSOR \/ 120-684","offer_id":50216937521437,"sku":null,"price":142.73,"currency_code":"CAD","in_stock":true},{"title":"YORK\/ETC FLAME SENSOR \/ S1-02532661002","offer_id":50216937554205,"sku":null,"price":142.73,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/d8961b89c3404c97adecb7534d9d9bfc.webp?v=1773964602","url":"https:\/\/bcfurnace.myshopify.com\/products\/120-684","provider":"BCFurnace","version":"1.0","type":"link"}
