Many LG refrigerators include an ice and water dispenser on the front of the refrigerator. The ice and water dispenser also has a control panel that, in addition to controlling the dispenser settings, allows you to adjust the internal temperature of the refrigerator. By default the internal temperature is set to Fahrenheit; however, it is designed to be easily changed to Celsius. If at any time you would like to switch the temperature readout back to Fahrenheit, you can do so with the touch of a button.
Locate the "Freezer" and "Refrigerator" buttons on the ice and water dispenser control panel.
Press and hold the "Freezer" and "Refrigerator" buttons simultaneously.
Release the "Freezer" and "Refrigerator" buttons when the temperature display changes from Fahrenheit to Celsius, which takes approximately five seconds.
