Display shows AL or an alarm icon, often with beeping, indicating temperature or door alarm.

Safety first: Ensure the door is closed to prevent condensation and slipping hazards.

• Check door closure: Verify that baskets or food packages are not preventing the door from sealing. Adjust contents as needed.
• Inspect gasket: Clean and inspect the door gasket for damage. Replace if torn or deformed.
• Test door switch: On models with a mechanical switch, press it by hand and listen for the alarm to stop. If it does not, test the switch for continuity and replace if faulty. On models with a magnetic reed switch, ensure the magnet in the door is present and aligned.
• Allow cool-down: If the alarm is due to high temperature after loading warm food, allow 12–24 hours for temperature to stabilize.
• Further diagnosis: If the alarm persists with a closed door and normal load, check evaporator fan, compressor, and sealed system as for a high temperature fault.
