FAQ

This assembly is compatible with natural gas water heaters from Reliance, Whirlpool, A.O. Smith, Kenmore, State, and American. It is specifically designed for use in many 300 and 301 series units, as well as various 30, 40, and 50-gallon residential models.
This unit replaces OEM part number 100112330. It also cross-references with part numbers 9007876 and 9007877.
You likely need a replacement if the pilot light refuses to stay lit, if the igniter fails to spark, or if the water heater burner will not engage. These issues are often caused by a faulty thermopile that can no longer generate the necessary millivolts to keep the gas valve open.
This kit includes the pilot burner, the 750-millivolt thermopile generator, the igniter wire, the pilot tube with ferrule nut, and the mounting bracket.
The installation is straightforward for those comfortable working with gas appliances. You will need to turn off the gas supply, remove the burner assembly from the water heater, and unscrew the existing pilot assembly from the mounting plate. Once replaced, ensure all connections are secure and check for gas leaks before relighting the pilot.
Always ensure the gas supply is completely shut off before beginning work. When installing the new assembly, be careful not to bend or kink the pilot tube or the thermopile wire, as these are sensitive components. After installation, always perform a soap-and-water leak test on the gas connections to ensure a proper seal.
