The Whirlpool W10810046 is an authentic alternative Electronic Control Board made specifically for Whirlpool microwaves. All of its functions are coordinated and controlled by this complex circuit board. Through the control panel, it receives and interprets input from the user before delivering signals to the magnetron, turntable motor, and display, among other parts.The W10810046's microprocessor, a small but potent chip that can do complicated tasks, is its brains. It converts user-specified parameters, such as cooking time and power level, into precise directions for additional parts. For instance, the microprocessor boosts the magnetron's power output when you select the "high power" preset, producing the microwaves that heat your meal. The control board also controls the ventilation and lighting systems and shows information on the user interface.
