Display shows E7 and the condenser fan at the rear does not run, causing overheating.

Safety: Unplug the cooler before removing the rear panel.

• Access the condenser fan: Remove the rear lower cover to expose the condenser coil, compressor, and condenser fan.
• Clean the area: Use a soft brush and vacuum to remove dust from the condenser coil and fan blades. A clogged condenser can overheat the system.
• Check fan movement: Spin the fan blades by hand. If stiff or seized, the motor is likely bad.
• Inspect wiring: Verify the fan connector is secure and wires are intact. Look for signs of overheating or melting at the plug.
• Test the fan motor: Measure resistance across the motor leads. An open circuit indicates failure. If possible, briefly power the fan with an appropriate DC supply to confirm.
• Replace the condenser fan: Install a new condenser fan motor assembly compatible with your Antarctic Star wine cooler. Ensure correct airflow direction (usually blowing air through the condenser coil).
• Control board check: If the fan is good but never receives power when the compressor runs, the main control PCB may be defective and need replacement.
