Good news first: "OF OF" (or "O FF") on a Samsung refrigerator is NOT a broken fridge — it's **demo mode** (also called showroom or cooling-off mode). Stores use it so a fridge lights up on the sales floor without running the compressor. If it got switched on by accident, the display works but the fridge doesn't cool. The fix is free and takes about 10 seconds. Here's how to get out of it.
OF OF means the fridge is in demo mode — cooling is intentionally turned off. It gets switched on by accident, or a fridge bought as a floor model was never taken out of it. The fridge is fine; it's just not running the cooling.
Check it: Exit demo mode with the button combo for your model (with the doors open): hold **Energy Saver + Fridge (Power Freeze + Power Cool on some)** for about 8 seconds, or **Freezer + Fridge** together — until you hear a chime and the temperatures reappear. Check your model's manual for the exact two buttons. Once it exits, give it a few hours to cool down.
Different Samsung models use different button pairs, so the first combo may not be the right one for yours.
Check it: Try the other common pairs (Power Freeze + Power Cool, or Fridge + Energy Saver) held ~8 seconds with the doors open. When it works, OF OF disappears and real temperatures show.
If you've confirmed demo mode is off and real temps show but it still won't cool after several hours, then it's a genuine cooling issue (fan, defrost, or sealed system) — separate from the OF OF.
Check it: If cooling doesn't return within a few hours of exiting demo mode, that's a real repair — a tech diagnoses the fan/defrost/sealed system.
Free — exiting demo mode costs nothing and fixes the vast majority of "OF OF, not cooling" cases. Only if cooling truly doesn't return afterward is it an actual repair.

It's demo/showroom mode — cooling is intentionally turned off (stores use it so the fridge lights up without running). It's not a breakdown. Exit demo mode and cooling comes back.
With the doors open, hold the right two buttons for your model for about 8 seconds — commonly Energy Saver + Fridge, Power Freeze + Power Cool, or Freezer + Fridge — until you hear a chime and real temperatures appear. Then give it a few hours to cool.
The classic cause is demo mode (OF OF on the display) — the panel works but cooling is off. Exit demo mode first. If it still won't cool after a few hours, it's a real repair and your $50 Quick Check credits toward it.
