The Whirlpool WPW10340992 is an indispensable part for your refrigerator's ice maker functionality. It's a wire harness, or arrangement of electrical wires, that serves as a communication interface between the ice maker and your refrigerator's main electrical system. This wire harness transfers power and signals between these components.Imagine the ice maker as a factory that requires instructions and ingredients to manufacture ice. The wire harness functions as a conveyor belt. It provides electrical current to run the ice maker's pump and other components. It also transmits signals from the ice maker to the refrigerator's control board, notifying it of the ice maker's status, such as the water fill level or the ice bin's capacity. This two-way communication guarantees that the ice maker works efficiently.
