Freezer beeps continuously and displays AL or a flashing high-temperature icon; interior temperature is too warm.

Safety first: This alarm indicates unsafe food temperatures. Minimize door openings and handle food appropriately.

• Check door closure: Ensure the door closes fully and is not obstructed by baskets or oversized items. Adjust contents so the door can seal properly.
• Inspect door gasket: Run your hand around the door seal to feel for cold air leaks. Look for tears, gaps, or hardened sections. Replace the freezer door gasket if damaged.
• Allow recovery time: If you recently added a large quantity of warm food or had a power cut, allow 12–24 hours for the freezer to pull down to temperature. Keep the door closed as much as possible.
• Check temperature setting: Confirm the set temperature is appropriate (typically around -18°C). Adjust if necessary.
• Monitor performance: Place a freezer thermometer inside and verify that the temperature drops below -15°C within several hours. If it does not, there may be a cooling system issue.

When to call a technician: If the alarm persists and the freezer cannot reach proper temperature despite a good door seal and correct settings, a sealed system or compressor fault is likely and requires professional service.
