This premium Flame Sensor Rod is a vital safety and performance component designed for high-efficiency gas furnaces and HVAC systems. As a critical part of the ignition sequence, this rod detects the presence of a flame and sends a microamp signal to the furnace control board. If the sensor fails to detect a flame, it triggers a safety shut-off to prevent unburned gas from entering the home. If your heating system starts but shuts off after a few seconds, a corroded or faulty flame sensor is often the cause. This replacement rod is engineered for durability and high-temperature resistance, ensuring reliable flame rectification and preventing unnecessary system lockouts in Lennox, Armstrong, and Ducane equipment.
