Samsung Fridge 'OF OF' Code: What It Means and How to Turn It Off
OF OF — also displayed as O FF — is not an error at all. It means your Samsung refrigerator is in Cooling Off mode, also called demo or shop mode. The lights and display work, but the compressor does not run, so nothing actually gets cold.
Cooling Off mode exists for store displays: the fridge looks alive on the showroom floor without using power to refrigerate an empty box. It sometimes gets switched on accidentally — by curious kids, during cleaning, or after certain button combinations are pressed. The fix takes under a minute and needs no tools.
Common causes
- The fridge was switched to demo mode in a store and never switched back
- Cooling Off mode was activated accidentally by pressing the control panel
- Curious children playing with the display buttons
- The mode re-enabled after a control reset or power event (rare)
How to fix it, step by step
- Find your model's button combination. On most Samsung models you press and hold two buttons together for about 5–10 seconds until the fridge chimes. Common pairs are Energy Saver + Freezer, or Fridge + Freezer (Power Cool + Power Freeze on some models).
- Hold until you hear the chime. Keep holding — the display will blink and the fridge will beep. OF OF disappears and real temperature numbers appear instead.
- Listen for the compressor. Within a few minutes you should hear the compressor and fans start. That sound means real cooling has begun.
- Verify temperatures later. Check after a few hours that the fridge is heading toward about 37°F (3°C) and the freezer toward 0°F (-18°C).
- Check your model's manual if the combo differs. Button pairs vary by model family. Samsung's support site lists the exact combination for each model if the common ones do not work.
If you just bought the fridge and it has never felt cold, do not assume it is broken and book a repair — check for OF OF first. It is one of the most common 'faulty' new-fridge calls, and it is free to fix.
Frequently asked questions
Is OF OF an error code?
No. It is a mode indicator: Cooling Off (demo) mode. The fridge is deliberately not cooling.
Why is my Samsung fridge's display working but it's warm inside?
That is the classic OF OF symptom — lights and display on, compressor off. Turn off Cooling Off mode and cooling starts.
Will turning off demo mode delete my settings?
No. Your temperature settings stay as they are; the fridge simply starts actually cooling to them.
