Samsung Refrigerator OF OF — What It Means & How to Fix It
Also shown as OF, Off Off on some models.
OF OF on a Samsung refrigerator is demo mode (or Cooling Off): the fridge is running as a showroom unit with cooling disabled. It's a setting — not a fault — and it exits with an 8-second button hold.
What this code means
OF OF is Samsung's display for demo mode, also called showroom mode: the control board keeps the displays and lights alive but never switches on the compressor, so the refrigerator holds room temperature. It's almost always left on accidentally — a retailer demo unit, or a panel was pressed during cleaning — and on some models the words Cooling Off appear instead, doing the same thing. The giveaway that it's a mode and not a fault: everything else behaves exactly as if the fridge had power, just never cold.
Samsung's official guidance for demo mode on refrigerator models is to hold the top two-left buttons (Power Cool and Power Freeze) together for about 8 seconds until a beep confirms it's off. On Family Hub models the toggle lives in Settings under Fridge Manager. The identical exit procedure applies whether the display shows OF OF or the Cooling Off wording.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Demo mode left on from a showroom unit | Very common | Yes — 8-second button hold |
| Buttons pressed during cleaning or a power event | Common | Yes — hold to exit |
| Cooling Off toggled in settings | Occasional | Yes — Fridge Manager |
| Board stuck in the mode despite exiting | Less common | Partly — reset first, then service |
What you can try yourself
- Find the Power Cool and Power Freeze buttons — the top two buttons on the LEFT side of the control panel on most models.
- Press and hold both together for about 8 seconds, until the display beeps or the code disappears.
- On Family Hub models, go to Settings > Fridge Manager and make sure Demo mode is turned off.
- If the fridge still shows OF OF, unplug it (or flip its breaker) for 60 seconds and repeat the button hold after it reboots.
- Give the compressor a few hours to pull the fridge down to temperature once the mode clears.
When to call a technician
- The display still reads OF OF after a proper 8-second hold and a full power reset.
- The fridge never gets cold even after the code clears — that's a separate, real cooling fault.
- A burned smell or a warm-to-the-touch cabinet in a unit that was never in demo mode.
Typical professional repair cost: No repair cost — this is a settings mode. If the board refuses to exit the mode, a technician's service visit to reflash or replace it runs $100–$250.
Frequently asked questions
Is OF OF the same as the fridge failing?
No. OF OF means the unit was put into demo mode — intentionally or by accident — and the compressor is being told not to run. No parts, no refrigerant, no fault: a setting to reverse.
I bought a used fridge and it sat warm all the way home — is that this?
That sounds exactly like it. A dealer's demo or a returned unit can ship with demo mode left on, and nothing cooler more than the air around it reads as OF OF until you exit the mode.
Do I hold both buttons for exactly 8 seconds?
About eight — hold until you hear the confirm beep and the display changes. Less than that sometimes registers as ordinary button presses; longer is harmless.
