This 8-inch flame sensor rod with an attached lead is a critical safety component for residential gas furnaces and HVAC systems. Specifically designed for use in Olsen and Airco heating units, this sensor ensures that your furnace operates safely by detecting the presence of a flame once the gas valve has opened. Utilizing the principle of flame rectification, the rod sends a microamp signal to the furnace control board; if the sensor fails to detect a flame, it immediately shuts down the system to prevent hazardous gas buildup. If your furnace is short-cycling or failing to stay lit after ignition, a dirty or oxidized flame sensor is often the cause. This high-quality replacement features a durable metal rod and a high-temperature ceramic insulator to withstand the intense heat of the burner assembly, restoring reliable ignition and efficient heating performance to your home.
