The Whirlpool W10818724 is a cooktop replacement for electric ranges manufactured by Whirlpool, Jenn-Air, KitchenAid, Maytag, Amana, Inglis, and Magic Chef. It's the smooth surface on which you cook, with the burners and heating equipment. Electric cooktops use electricity to generate heat, which allows for precise temperature control. Once fitted, the cooktop uses knobs or touch controls to activate the desired burner. The heating components then deliver heat to the cookware. This replacement cooktop has the advantage of restoring full functioning to your range if your current cooktop is cracked, damaged, or defective. Because it is a genuine Whirlpool item, it should be compatible and fit properly with your appliance.
