The AL alarm code (or “AL” / “HI” on some models) on a Kenmore upright or chest freezer indicates the internal temperature has risen above the safe threshold — typically above 15°F (-9°C). This is a food safety warning requiring immediate action.
Causes
- Freezer door left open or door seal failure
- Overloading with warm food items
- Condenser coils frosted over (loss of cooling efficiency)
- Compressor failure or refrigerant leak
- Ambient temperature too high around the freezer
What To Do
- Verify the door is fully closed and the door gasket seals completely around the frame.
- Check food — if partially thawed, move to another freezer or discard if temperature has been above 32°F for more than 2 hours.
- Allow 24 hours for the freezer to reach proper temperature before concluding there is a mechanical fault.
- If the alarm persists with the door confirmed sealed, contact a technician to test the compressor and sealed system.
