American Water 100093817 Thermocouple Lp Gas FG-30S30

Product Description

The AMERICAN WATER 100093817 is a replacement thermocouple designed for LP gas Flameguard water heaters, specifically the FG-30S30 model. A thermocouple is a safety device that monitors the pilot flame and sends a small electrical signal to hold the gas valve open. If the pilot goes out, the thermocouple cools, the signal drops, and the gas valve closes automatically. This OEM-style replacement restores that critical safety function. Installation is performed by licensed plumbers or water heater service technicians familiar with gas appliance safety systems.

This thermocouple is intended for use in LP (liquid propane) gas-fired Flameguard series storage water heaters. The Flameguard design incorporates a sealed combustion chamber with a flame arrestor screen to reduce ignition of flammable vapors near the appliance. Replacing a failed or degraded thermocouple on this type of unit requires matching the correct probe length, tip style, and connection fitting to ensure proper pilot sensing and gas valve compatibility.

Key Features

• Designed specifically for LP gas service on Flameguard water heaters
• Restores pilot safety shutoff function when original thermocouple fails
• Direct replacement for the FG-30S30 model application
• Part of the water heater components and accessories product line from American Water Heaters

Compatibility

Designed as a direct replacement thermocouple for the American Water Heaters FG-30S30 LP gas Flameguard series water heater.

Installation Notes

Installation should be performed by a licensed plumber or qualified gas appliance technician. Before servicing, shut off the gas supply to the water heater and allow all components to cool completely. Thermocouples thread into the gas valve connection and position the probe tip in the pilot flame path — ensure the tip is seated correctly in the pilot bracket for reliable flame sensing. Work must comply with applicable local plumbing and gas codes, including IFGC requirements for gas appliance servicing.
