Display shows E8 and the unit shuts down or beeps, often related to high temperature or overheat.

Safety: Turn off and unplug the cooler before cleaning or moving it.

• Check installation clearance: Ensure there is at least the manufacturer-recommended clearance (typically 2–4 inches) at the back and sides of the Antarctic Star wine cooler for proper airflow.
• Clean condenser and vents: Remove the rear cover and vacuum dust from the condenser coil, compressor area, and any ventilation grilles. Clean front kick plate vents as well.
• Allow cooling: If the compressor is very hot to the touch, leave the unit unplugged for 30–60 minutes to cool down, then restore power and see if E8 clears.
• Inspect overtemp sensor: Some models use a dedicated overheat sensor near the compressor or condenser. Check its wiring and connector for damage.
• Verify ambient conditions: Ensure the cooler is not installed in a very hot environment (e.g., garage above 90–95°F), which can trigger overheat protection.
• Replace faulty components: If the overtemperature sensor is defective, replace it with the correct overheat / safety thermostat or thermistor. If the error persists with proper cooling and good sensors, the main control PCB may need replacement.
