How to replace a range spark igniter electrode

This DIY repair guide gives instructions on how to replace the spark igniter electrode for the surface burner on a freestanding gas or dual-fuel range, but can be adapted to a built-in range as well. Replace the spark igniter electrode with a manufacturer-approved replacement part if you see physical damage or if the spark won't light the burner because the ceramic insulation below the electrode tip cracks.

This basic procedure works for Kenmore, Frigidaire, Whirlpool, Maytag, Amana, GE, LG and Samsung ranges.
