How do I reset my fridge?
How do you reset the freezer on an LG refrigerator?
With either refrigerator door opened press and hold the REFRIGERATOR and ICE PLUS buttons at the same time for five seconds. After holding the buttons for five seconds, the control panel will beep, and the temperature settings will display to confirm that DEMO MODE is deactivated.

Check the Temperature Control Thermostat
Another possible cause of your refrigerator not cooling is a faulty temperature control thermostat. The thermostat is responsible for directing voltage to the evaporator fan motor, the compressor, and, if your fridge has one, the condenser fan motor.
