Display shows AL01 and an audible alarm sounds; temperature may be too high.

Immediate steps:

• Ensure all doors are fully closed and seals are intact.
• Check if there was a recent power cut or if the appliance was just installed or restarted; if so, allow 12–24 hours for temperatures to normalize.
• Reduce overloading: rearrange or remove items blocking vents and ensure air can circulate.

Further checks:

• Listen for compressor and internal fans running. If silent, check the power outlet and household breaker.
• If the alarm persists after several hours of normal operation, there may be a cooling system fault requiring professional diagnosis.
