If you suspect that the control module is damaged and causing the malfunction of your ice maker, you should replace it. The control module handles control of various functions of the appliance, such as initiating the ice-making cycle and signaling the water valve to fill the ice tray.
Contact an authorized Maytag service center or an appliance technician for an appropriate replacement. They can help you identify the correct replacement part based on your specific model and guide you through the installation.
