The Whirlpool WP7431P066-60 Range Surface Burner Spark Module is a vital component for your electric range cooktop. It is responsible for generating the spark that illuminates the gas burners on your stove. When you turn a burner knob, the ignition module generates a high-voltage spark that passes across the igniter electrode before entering the burner cap. This ignites the gas, which produces a flame. Without an operational spark module, your burners would not light and you would find yourself impossible to cook. A faulty spark module is a characteristic reason for gas ranges refusing to ignite. Replacing an incorrect spark module is a simple repair that can be performed by a do-it-yourselfer or an authorised appliance professional.
