Whirlpool 12002788 Range Igniter Switch With Shield

The Whirlpool 12002788 is an indispensable part for your gas range, specifically the igniter switch with shield. This switch is responsible for starting the spark that lights your cooktop's gas burners. When you turn a knob on your range, the igniter switch activates. This transmits a little electrical current to the igniter, which is a small metal rod placed near the burner. The current generates a spark that travels across the gap between the igniter and the burner cap, igniting the gas that flows from the burner orifice. The shield around the switch protects it from heat, oil, and spills that may occur during typical cooking.A malfunctioning igniter switch could be the cause of burners that fail to ignite or require repeated attempts.
