The Ice maker is a fairly simple mechanical device made of six main components. The control module, which contains a small motor, that drives a gear with a conductive pattern on the back, energizing various components at the proper time as it rotates. The harvesting arm removes formed ice cubes. The ice maker thermostat is normally open and closes temporarily when the ice has frozen energizing the mold heater and causing the motor to rotate again. The mold heater warms the mold causing your ice cubes o melt slightly for easy removal. The bail arm opens and closes a small contact inside the control module interrupting power if it senses the ice bin is full. Lastly the water valve supplies the high quality h2O necessary for ice production.
ce makers do not have any kind of a water level sensor like a washing machine does, instead they fill for a set period of time as the rotation of the timer temporarily energizes the water valve. Ice makers are set at the factory for average household water pressure. However, if you start to have problems with individual ice cube groups connected along the top, icicles hanging from the icemaker, your ice container floor covered with ice, or small cubes, you can correct the problem by adjusting how long the valve is energized with a screw located on the ice maker module. Adjustment is usually clockwise to reduce fill time and counter clockwise to increase it. Be careful a little goes a long way.
