The Whirlpool 12001296 is a suitable equivalent kit that includes both the igniter and knob for your Whirlpool range's surface burner. The igniter is an essential component that produces the spark required to ignite the gas on your cooktop. When you turn the knob, it triggers a switch that feeds current to the ignition. This current produces a little electrical spark that jumps over the distance between the igniter tip and the burner head, igniting the fuel. This kit has been made for Whirlpool ranges with an electronic ignition system rather than a pilot light. Replacing a malfunctioning igniter and knob is an obvious repair that may be completed at home with only a screwdriver.
