Lochinvar & A.O. Smith 100111979 Sensor 318973-401 Specifically engineered for the RK-603DThe Lochinvar & A. O. Smith 100111979 Sensor is a high precision flame sensor designed for gas fired boilers and water heaters. As a critical safety component, this replacement flame sensor utilizes flame rectification to monitor the burner constantly. When the control module receives a signal of at least 10 microamps, it confirms a stable pilot or main burner flame, ensuring the gas valve remains energized. If the 100111979 sensor fails to detect
