  • Damaged fan blade
  • Defective motor
  • Broken wires

Fixing Method: Regardless of the cause of the evaporator fan failure, the recommended solution is to replace it.

4. Malfunctioning Thermostat Signs

The LG freezer’s thermostat or thermistor is responsible for measuring the temperature of the freezer compartment. A working thermostat sends a signal to the freezer control board to start or stop the cooling process as needed.

If the thermostat is faulty, it may send incorrect temperature readings, causing the freezer to stay too cold or too warm, inconsistent temperature readings on the thermostat display, the compressor running excessively, and the freezer taking longer than usual to reach the desired temperature.

Unfortunately, the thermostat cannot be repaired and must be replaced.

So, how can I know if the Thermostat works fine or not?

To test the thermostat, use a multimeter to check for electrical continuity. If there is no continuity, the thermostat needs to be replaced.

Here are some additional tips for replacing the thermostat:

  • Make sure to unplug the freezer before you start work.
  • Disconnect the wires from the old thermostat.
  • Install the new thermostat in the same location as the old one.
