Lennox 59837 Flame Sensor Rod

The Lennox 59837 Flame Sensor Rod is an essential safety component that is used in gas-fired heating products such as furnace and boilers. It is a metallic rod usually measuring 6.0 Inches in length and 3/16 Inches in diameter and is fitted into the burner assembly. The rod is designed to sense the ionization current that occurs at the time of burning of the flame. This current passes through the rod to the control board to maintain the position of the gas valve. If the flame is extinguished, the current stops, and the control board turns off the gas supply to avoid a leakage. This critical safety feature will guarantee the safe and proper functioning of your HVAC system.
