The Whirlpool WPW10157415 is a vital component for gas ranges, particularly as a surface burner orifice holder. It governs the flow of gas to your range burners. This small component typically screws onto the gas line and houses the orifice, a tiny nozzle that controls the amount of gas that flows through. When you crank the burner knob, the gas valve opens and allows gas to flow through the orifice and into the burner. The orifice size stipulates the intensity of the flame, consequently the orifice holder indirectly governs your cooking heat. This genuine Whirlpool part has been engineered to fit and function effectively in an array of Whirlpool, Jenn-Air, Kenmore, KitchenAid, and other compatible models.
