The Whirlpool WP74007806 is an essential part of your Whirlpool cooktop. A wire harness combines a switch and a wire assembly. This component is critical for the ignition of your burners. When you turn the knob on your range to activate a burner, the switch in the WP74007806 assembly sends a signal over the wires. This signal activates the spark ignition module, which creates a spark and ignites the gas coming from the burner. In essence, this switch wire assembly connects your control panel to the spark ignition system, ensuring a smooth and safe gas lighting procedure on your cooktop. A faulty WP74007806 may cause issues with burner ignition, resulting in annoyance and cooking delays.
