Freezer beeps and displays AL or a flashing alarm symbol; temperature is too high and food may be soft.

Safety: No internal electrical work is required for basic checks. If you proceed to internal components, unplug the freezer first.

• Check door closure: Ensure the door is fully closed and the gasket is not obstructed by food packages or ice.
• Inspect door gasket: Run your hand around the seal to feel for cold air leaks. Clean the gasket with warm soapy water and dry.
• Consider recent events: If you recently loaded a lot of warm food or had a power cut, the alarm may be normal. Press the alarm reset button (if available) and allow 12–24 hours for temperature to recover.
• Check internal airflow: Make sure vents inside the freezer are not blocked by food. Air must circulate freely.
• Listen for compressor and fan: You should hear the compressor and, on no-frost models, the evaporator fan. If either is silent for long periods while the interior is warm, further diagnosis of those components is needed.
• Monitor temperature: Use a freezer thermometer to verify actual temperature. If it does not drop below –18°C after 24 hours with the door closed, there may be a sealed system or control fault requiring a technician.

If the alarm persists despite good sealing and normal loading, professional diagnosis of the cooling system is recommended.
