How to replace a spark igniter switch on a gas cooktop

This repair guide provides step-by-step instructions on replacing the spark igniter switch in a gas cooktop. The spark igniter switch is located on the stem of the burner control valve. Replace the spark igniter switch with a manufacturer-approved replacement part if the burners don't spark when you turn the burner control knob to the Lite position or if igniters spark constantly even when the burners are off.

Use these steps to replace a spark igniter switch in Kenmore, Frigidaire, Electrolux, Whirlpool, GE, KitchenAid, Maytag and Amana gas cooktops.
