The AMERICAN WATER 100093816 is a replacement thermocouple designed for LP gas FlameGuard water heaters. A thermocouple is a safety sensing device that monitors the pilot flame and signals the gas valve to stay open when a live flame is detected. If the pilot goes out, the thermocouple cools and the gas valve closes automatically, preventing unburned gas from accumulating. This part is a direct replacement component for the FG-50T40 FlameGuard model and is installed by licensed plumbers or water heater service technicians during routine maintenance or pilot assembly service calls.
This thermocouple is specified for LP gas FlameGuard water heaters, specifically the FG-50T40 model. FlameGuard water heaters use a sealed combustion chamber design that requires components engineered to meet their ignition and safety system requirements. This part is suited for residential service work where the existing thermocouple has failed, shows signs of oxidation, or no longer holds the pilot valve open reliably after the pilot is lit and the reset button is released.
Specified as a replacement thermocouple for the AMERICAN WATER FG-50T40 LP gas FlameGuard water heater.
Thermocouple replacement on gas water heaters is typically performed by a licensed plumber or gas appliance technician. Before beginning, shut off the gas supply at the appliance shutoff valve and allow the unit to cool completely. The thermocouple tip must be positioned correctly in the pilot flame to ensure reliable signal output to the gas valve. Work must comply with applicable local gas codes and the manufacturer installation instructions for the FG-50T40 unit.
