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.
