We have the igniter you need to repair your water heater. In a gas water heater, the igniter is the part that ignites the natural gas that burns to heat the water. We stock igniters made to fit a number of water heater models, including Suburban, Atwood, Weil-McClain AHE, GV, HE II, Rheem, AO Smith, and more. Be sure to check the specifications of your water heater so you can select the correct part.
