Hello;
My name is Peter. I am a retired field refrigeration technician.
It sounds like your ice maker has a bad motor module/circuit board.
It is like a control board. This module reads a temperature sensor that indicates the water is frozen and ready for harvesting the ice cubes. Then it turns on a electric heater under the ice cube mold, then turns on the motor to harvest the ice cubes. After the ice cubes are harvested, it opens the water supply solenoid valve to fill the mold with water. The ice maker needs to be replaced.
