Samsung Refrigerator OF OF Code: Causes & Fix

What is the Samsung Refrigerator OF OF error?#

OF OF on a Samsung refrigerator — sometimes shown as a variant of the same letters — is not actually an error: it is Cooling Off, or shop demo mode, where the lights and display stay on but the compressor never runs so the interior does not get cold. That is why the classic signs are working lights and a working display alongside a unit that simply is not cooling, with no fan noise. It matters because food will spoil while demo mode is active, so catch it quickly. The fastest fix is a button combination: on most models, press and hold Energy Saver and Power Freeze together for a few seconds until you hear a chime.

OF OF on a Samsung Refrigerator: likely causes and repair cost#

On a Samsung Refrigerator, the OF OF code signals: cooling off / demo mode.

Typical professional repair: up to $120 · Difficulty: easy · often owner-fixable

Fastest thing to try first: Press and hold Energy Saver + Power Freeze for 3 seconds.

Symptoms that often accompany OF OF: Display shows "OF OF" or "O FF"; Interior lights work but unit is not cold; Compressor never runs; No fan noise from the unit

Technician diagnostic sequence for OF OF:

1. This is not an error — the refrigerator is in "Cooling Off" (shop demo) mode, where the display and lights work but the compressor does not run
2. To exit demo mode on most Samsung models: press and hold the Energy Saver and Power Freeze buttons simultaneously for 3-5 seconds until you hear a chime
3. On newer Touch models (2020+): press and hold the Freezer and Fridge temperature buttons simultaneously for 5 seconds
4. If button combinations do not work, unplug the refrigerator, wait 2 minutes, then plug in while holding the Energy Saver button — release after 5 seconds
5. If none of the documented resets exit demo mode, the control board is stuck and needs a technician to reflash or replace it — the only scenario in which OF OF costs anything to fix

Parts a technician may check or replace: Main control board

Field note: Demo mode is commonly activated during installation when the installer tests the display, or by children pressing button combinations. Samsung demo mode disables all cooling while keeping lights and display active — food will spoil if not caught quickly. Nearly always the button reset clears it for free; only a board that refuses every documented reset is a genuine repair.

How to troubleshoot the OF OF error yourself#

OF OF is a settings state, not a broken part, so this is almost always an owner fix. The mode is usually switched on by accident — an installer testing the display, or children pressing buttons — and it disables cooling while keeping the lights and screen alive. To exit on most Samsung models, press and hold the Energy Saver and Power Freeze buttons at the same time for three to five seconds until a chime confirms the change. On newer touch models, holding the Freezer and Fridge temperature buttons together for five seconds does the same job. If the button combinations do nothing, try unplugging the refrigerator for two minutes, then plug it in while holding the Energy Saver button and release after five seconds. Because food spoils while the unit is not cooling, deal with this the moment you notice it. The only case that leaves DIY behind is a control board that refuses every documented reset — then a technician has to reflash or replace it, and that is the sole scenario where OF OF costs anything.

Is the Samsung Refrigerator OF OF error worth fixing?#

OF OF is nearly always free to fix, because it is a mode, not a malfunction. The documented button resets clear it at no cost on the vast majority of units, so most owners spend nothing beyond a minute of button-holding. The only time a repair enters the picture is a control board genuinely stuck in demo mode after a firmware glitch that ignores every reset — then the professional cost tops out around $120 to reflash or replace the board. Even that ceiling is trivial against a new refrigerator, so a stuck board is still worth fixing. In short: try the button combinations first, since they almost always work for free, and treat a paid repair as the rare exception rather than the rule.

Samsung Refrigerator OF OF: frequently asked questions#

What does the OF OF error mean on a Samsung Refrigerator?#

OF OF is not a fault — it means the fridge is in Cooling Off, or shop demo mode, where the lights and display work but the compressor never runs. It is usually switched on by accident.

Is it safe to keep using a Samsung Refrigerator that shows the OF OF error?#

No — because cooling is disabled, food will spoil, so treat it as time-sensitive even though nothing is broken. Exit demo mode promptly to restore cooling.

Can I clear the OF OF error myself, or do I need a technician?#

You can almost always clear it yourself with the button combination — holding Energy Saver and Power Freeze together. Only a board stuck in demo mode after every reset needs a technician.

How much does it cost to repair the OF OF error on a Samsung Refrigerator?#

The button reset costs nothing. In the rare case of a control board stuck in demo mode, a professional fix tops out around $120 to reflash or replace it.

Which parts usually fail when a refrigerator throws the OF OF code?#

Usually no part has failed at all — it is a mode that got switched on. Only a control board stuck in demo mode despite every documented reset counts as a genuine failed part.

Why does demo mode enabled trigger the OF OF error?#

Demo mode tells the fridge to run its lights and display while holding the compressor off, for showroom use. When it is activated by accident, the unit shows OF OF and stops cooling until the reset combination switches the mode back off.
