Ice Maker Not Working in Thomaston

Ice maker systems in premium refrigerators involve water inlet valves, fill tubes, ejector mechanisms, thermistors, and control modules. The cycle begins when the thermostat detects the mold is warm enough, triggering the water inlet valve to fill the mold. After freezing, a heater slightly warms the bottom of the mold while the ejector mechanism pushes cubes into the bin. A bail arm or optical sensor detects when the bin is full. Sub-Zero ice makers use specialized components designed for the precise temperatures of their dual-zone systems. Common causes of ice maker not working include: • Water inlet valve solenoid failure prevents water from entering the fill tube • Water supply line kinked or frozen blocks water flow completely • Fill tube frozen from excessive water pressure or defrost issues • Water filter clogged reduces flow below minimum required for filling • Ice maker module (motor assembly) mechanically worn or electrically failed Ice maker modules vary by refrigerator model year. Verify exact model and serial number before ordering. Some units use modular ice makers while others have integrated systems. Sub-Zero ice makers are proprietary designs.
