LG Refrigerator (French Door) OF F error code

Difficulty: Easy · Cost: $0 · Duration: 1m

OF F is not an error code. It means your LG refrigerator is currently in Demo Mode, also called Display Mode. This feature is designed for retail stores and disables all cooling in both the refrigerator and freezer sections to save energy while the unit is on display. If your refrigerator is showing OF F at home it means Demo Mode was accidentally activated. Nothing is broken — the fridge simply needs to be switched back to normal operating mode, which takes about 5 seconds.

Common causes

  • Demo Mode was accidentally activated by pressing the wrong button combination
  • Refrigerator was purchased from a store and Demo Mode was not deactivated before delivery
  • Buttons on the control panel were held down accidentally triggering Demo Mode

How to fix it

  1. 1

    Open either the refrigerator or freezer door

  2. 2

    Press and hold the REFRIGERATOR button and the ICE PLUS button at the same time for 5 seconds

  3. 3

    The control panel will beep and the temperature settings will reappear on the display confirming Demo Mode is off

  4. 4

    Close the door and allow the refrigerator to cool down to its normal temperature — this may take a few hours
