Common causes

The fridge is in showroom/demo mode, often left on after delivery
Cooling Off mode was switched on accidentally by a control-panel button combination

What to check, in order

Safety first. Switch the appliance off and unplug it before checking anything inside it. If you are not comfortable with any step, stop and call a technician.

On the front control panel, press and hold the top two buttons on the left side together for 5 to 8 seconds, until you hear a chime; this is the most common method in Samsung's guide, though some models need a third button as well.
Wait a few moments and confirm the display does not slip back to OF OF; if it does, repeat the button hold until it stays off.
Confirm the display shows real temperatures and the compressor starts; the fridge should begin cooling within a few minutes.

Clear the code and test

Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
Plug the appliance back in and restore its water supply if it has one.
Run the shortest programme and watch the point where the code appeared before.
If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.

When to call a professional

This display is not a fault, so there is normally nothing to book. Call a technician only if the machine also behaves abnormally, or if any of these apply:

The code comes back after you have run the checks and a test cycle.
You smell burning, see sparks or scorch marks, or the breaker trips.
Water is leaking and you cannot stop it at the tap.
The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.

When you call, give the brand, the code OF OF, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
