E6 displayed; unit may start but quickly stops, often with unusual ice size or incomplete cubes

Safety: Disconnect power before reaching into the ice-making compartment.

Steps:

• Locate the thickness sensor: On many Antarctic Star ice makers, a metal or plastic probe or paddle near the evaporator tray detects ice thickness or position during harvest.
• Clean the probe: Mineral scale or slime on the probe can cause false readings. Clean it with a cloth soaked in a 1:1 mixture of white vinegar and warm water, then rinse with clean water.
• Check adjustment: Some models have an adjustable thickness screw or sliding bracket. Ensure the probe is positioned according to the user manual (typically just touching or slightly above the formed ice).
• Inspect wiring: Follow the probe wires back to the control board. Look for breaks, loose connectors, or corrosion. Reseat the connector.
• Reset and test: Reassemble, plug in, and run a cycle. Observe whether ice forms and releases correctly and whether E6 reappears.
• Replace sensor: If E6 persists and wiring is intact, replace the ice thickness sensor/probe assembly with the correct part for your Antarctic Star model.
