Freezer is too cold; food is freezing harder than normal, ice cream rock solid, temperature below setpoint.

Safety: Unplug the freezer before accessing sensors or control boards.

• Verify settings: Check the set temperature on the display. Adjust to a warmer setting and monitor for 24 hours.
• Check for demo/sabbath modes: Ensure the unit is not in a special mode that alters normal operation (refer to user manual).
• Test thermistor: If the freezer remains excessively cold, test the freezer thermistor with a multimeter and compare to LG specs. Replace if readings are inaccurate.
• Inspect control board: If the compressor runs almost constantly even when the interior is very cold, the main PCB relay may be stuck closed and will require replacement.

Persistent overcooling after sensor replacement usually indicates a faulty main control board; professional service is recommended.
