Freezer beeping with high temperature alarm, food starting to thaw after a power cut or door left open.

Safety: No internal repair is usually needed, but ensure food safety.

Steps:

• 1. Check door and seal: Make sure the door is fully closed and the gasket is sealing properly.
• 2. Reduce load: If you have just loaded a large quantity of unfrozen food, spread items out to allow air circulation and avoid blocking vents.
• 3. Silence alarm: Use the alarm mute button if available. The alarm will usually stop once the temperature returns to normal.
• 4. Monitor temperature: Use a separate thermometer to confirm that the freezer returns to -18°C or below within several hours.
• 5. If temperature does not recover: Then treat as a cooling fault and follow the relevant troubleshooting steps for poor cooling.

Food safety: If food has thawed completely and remained above -10°C for many hours, it may be unsafe to refreeze.
