This is the main electronic control board (smart board) that manages all microwave functions, including cooking times, power levels, and keypad inputs. It processes signals from the touchpad and controls the magnetron, turntable motor, and other components. Replace this board if the microwave is unresponsive, displays error codes, has intermittent operation, or if buttons no longer function properly.
