Display O-FF

Display blinks 'O-FF' - Cooling Off (Demo) mode active

Samsung · Refrigerators

What does Display O-FF mean?

The Refrigerator is operating in Cooling Off mode, also known as Demo Mode (North America models). This mode is primarily for display purposes, so the compressor does not operate, meaning the Refrigerator will not cool. Other functions like the display and fan motor will work, and 'O-FF' will blink on the temperature setting display.

Common Causes

  • The Cooling Off mode was activated, potentially by pressing the Refrigerator and Power Cool buttons for 6 seconds, then the Door Alarm button.
  • The Refrigerator was left in this mode after an initial setup or demonstration.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Ensure the Refrigerator is not intended for display use; if so, this mode is normal.

  2. 2

    To exit, press the Refrigerator and Power Cool buttons simultaneously for at least 6 seconds until the display blinks.

  3. 3

    While the display is blinking, press the Door Alarm button once.

  4. 4

    Verify that 'O-FF' is no longer displayed and the Refrigerator begins to cool normally.

  5. 5

    If the mode persists, unplug the Refrigerator for a minute and plug it back in, then retry the button sequence.
