Rheem AP15105 Flame Sensor Rod

This Rheem component is a flame sensor rod designed to detect and confirm the presence of a flame in gas heating systems. The primary function of this device is to ensure that gas is only supplied when a flame is present, thus preventing unburned gas from being released into the system. Constructed from durable materials, it features an elongated rod shape for easy installation and optimal performance. The sensor operates by generating a small electrical current when heated by the flame, which signals the control board that combustion is occurring. This safety mechanism helps to maintain efficient operation and reduce the risk of potential gas leaks or explosions.
