This premium flame sensor rod is a vital safety component for residential gas furnaces within the Lennox, Armstrong, and Ducane families. Designed to monitor the burner flame during the heating cycle, this sensor ensures that the gas valve remains open only when a flame is present. If your furnace starts and then shuts off after a few seconds, a soot-covered or failing flame sensor is often the culprit. Replacing the sensor rod is a common repair that restores reliable ignition and prevents your heating system from cycling or locking out. Engineered for durability and high-heat resistance, this replacement part helps maintain the safety and efficiency of your home's forced-air heating system.
