Features: Thermopile replacement part is compatible for Reliance, for Whirlpool, for A.O. Smith, for Kenmore, for State Replaces old for A.O. Smith # 6911197, 9007872005, 100094024. Thermopile temperature reaches up to 1202°F (650°C) and generates 750mV of power. Heating to 750mV takes approximately 60 seconds (2 minutes), ensuring efficient . Flame should heat to the middle of the head sensor for optimal performance. Made of high-quality materials, our thermopiles are designed to withstand the rigorous demands of continuous use. With an internal resistance of about 4000mΩ at 25°C, they provide reliable and long-lasting performance. Thermocouple assembly acts as a temperature sensor, detecting heat and generating a voltage signal to open or close the valve for gas flow. It serves as a direct replacement for old or damaged parts, without requiring any additional modifications or tools. Quick and easy installation.
