American Water Heaters Gas Control Thermostats

Overview

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. Key Features Designed for LP gas operation in FlameGuard water heater applications Direct replacement for the FG-50T40 model thermocouple assembly Functions as a pilot flame safety device that controls gas valve operation OEM catalog number 100093816 ensures correct fitment for specified models Compatibility Specified as a replacement thermocouple for the AMERICAN WATER FG-50T40 LP gas FlameGuard water heater.
