Possible Causes
How to Fix / Troubleshooting
Safety first: Do not ignore alarms if food safety is in doubt; verify temperature with a thermometer.
Steps:
- Check actual temperature: Place an accurate freezer thermometer in the middle drawer and wait several hours to confirm real temperature.
- Reset alarm: Press the alarm reset button. If the alarm returns quickly despite correct temperature, a sensor or control issue is likely.
- Inspect sensor: Locate the freezer compartment NTC sensor and check for damage or dislodging.
Remedy: Replace the freezer temperature sensor if readings are inconsistent. If the sensor is good, the main control board may need replacement.
