The Whirlpool WP9755451 Range Harness–Wire is an essential component of your Whirlpool range's ignition system. It is a set of wires that connects the spark igniter switches on your burner control knobs to the main electrical system. When you crank the ignition knob on a burner, the switch transmits a signal to the igniter via the harness. The igniter then generates a small spark that travels over the gap to the gas burner grate, igniting the gas and lighting the burner. This harness guarantees a smooth and dependable igniting process for all of your range burners. A working harness is required for safe and effective operation of your Whirlpool stove. A defective harness might result in problems such as burners failing to ignite.
