Freezer display shows LO or a low temperature alarm; interior may be colder than set point.

Safety first: Avoid prolonged contact with very cold surfaces to prevent skin injury.

• 1. Verify set temperature: Check the control panel and adjust the set point to the recommended value (typically around -18°C).
• 2. Power reset: Unplug the freezer for 5–10 minutes, then reconnect to clear any temporary control glitches.
• 3. Check sensor readings: If your model displays actual temperature, compare it with an independent thermometer placed inside. Large discrepancies suggest a sensor issue.
• 4. Observe compressor behavior: Listen to determine if the compressor runs continuously without cycling off. Continuous running with very low internal temperature may indicate a stuck relay on the main PCB.
• 5. Inspect main PCB: If accessible, check the board for signs of overheating around the compressor relay. Replacement of the board is usually required if the relay is stuck.
• 6. Replace faulty sensor: If the freezer is actually at normal temperature but the display shows very warm, the control may overcool. Replace the cabinet NTC sensor as needed.

Note: Persistent overcooling due to control faults should be addressed by a qualified technician to avoid food damage and excessive energy use.
