Samsung Refrigerator OF OF — Cooling Off Mode
OF OF is the display behind most 'new fridge won't cool' calls: the refrigerator is in its showroom mode, working exactly as designed — with cooling switched off.
What to check first
- Confirm it is the mode: the display shows OF OF, O FF, OFF OFF, or scrolling temperature bars, and the refrigerator lights and responds but does not cool.
- Exit it the most common way: on a front panel, touch and hold the top two buttons on the left side of the panel for 5–8 seconds, until a chime sounds.
- Wait a few moments and confirm the display does not return to Cooling Off; if it does, repeat the steps. Your model manual holds the exact steps for your model.
OF OF means the refrigerator is in Cooling Off Mode — sometimes called Demo mode or Shop mode. Samsung US: if the display is showing OF OF, O FF, OFF OFF, or scrolling temperature bars, the refrigerator is in Cooling Off Mode, and service is not required. The lights and panel work normally; only cooling is off, which is what a showroom needs and a kitchen does not.
Samsung is explicit that the exit steps are specific to each model and found in the user manual; it then gives the most common method, which is what the steps below print. Samsung Canada presents the same two-button hold as its method directly. Both presentations are Samsung's; where they differ in framing, this page keeps the US caution — the manual governs — because Samsung US states it in so many words.
Safety first
- Samsung's standing rule for its refrigerators (its US and Canadian lists): unless directed, do not unplug the refrigerator, and do not attempt any interaction with the panel to try to make the error code “go away” — doing either of these will make it harder for a technician to diagnose and correct the issue.
- The stop condition below is FixSignal's own general safety precaution, printed on every FixSignal guide; it is not a Samsung instruction. Samsung's guidance for this code is what this page prints from its Samsung sources.
- Stop condition — FixSignal precaution, not a Samsung code-specific instruction: If you notice smoke, a burning smell, damaged electrical parts, or significant water leakage, stop using the refrigerator. Do not touch a damaged plug, cable, or wet electrical area. If it is safe to do so, disconnect power; otherwise, keep clear and seek qualified assistance. Do not resume use until the hazard has been assessed.
Common causes
The mode was switched on — in a showroom, or carried home
Cooling Off is Samsung's display mode for retail: Samsung Canada's cause column says simply "fridge in showroom/demo mode". A refrigerator delivered from a display floor, or installed with the mode left on, shows OF OF in the kitchen until the mode is switched off.
Step-by-step checks
- Find the buttons for the most common methodSamsung US: the steps are model-specific and in your user manual; the most common method is for control panels on the outside front of the refrigerator, on the left side. Locate the top two buttons on the left side of the panel. On newer models, the top button on the right side is also necessary — but Samsung recommends trying with only 2 buttons first, as you are less likely to be in Cooling Off Mode accidentally on models which require 3 buttons.
- Touch and hold for 5–8 seconds, until a chime soundsSimultaneously touch and hold these buttons for 5–8 seconds, until a chime sounds. Samsung notes this chime sounds different from when a single button is touched. Samsung Canada gives the same window: 5 to 8 seconds, until you hear a chime.
- Confirm the mode has stayed offWait a few moments to confirm the display does not return to Cooling Off Mode status again. If it does, repeat the steps until you are successful (Samsung US); Canada adds: if the code returns, repeat the steps.
When to call a technician
There is no technician boundary for OF OF: Samsung states service is not required. If the mode will not stay off after the correct steps for your model — the manual's steps, not a neighbour model's — that persistence is the thing to raise with Samsung support, with the model number in hand.
Model differences
| What you have | What changes |
|---|---|
| Two-button vs three-button models | Most front panels exit with the top two left buttons; some newer models also require the top button on the right side. Samsung advises trying two buttons first. |
| Other panel layouts | Samsung: the steps to turn this mode off are specific to each model and can be found in your user manual — the manual outranks any general sequence, including this page's. |
| Scrolling temperature bars | The same mode in another display form: Samsung US lists scrolling temperature bars alongside OF OF, O FF and OFF OFF. |

Frequently asked questions
Is OF OF an error?
No. Samsung: OF OF, O FF, OFF OFF or scrolling temperature bars mean the refrigerator is in Cooling Off Mode (Demo/Shop mode), and service is not required. Cooling is switched off; nothing is broken.
What buttons turn off Cooling Off mode?
The most common method (Samsung US): touch and hold the top two buttons on the left side of the front panel for 5–8 seconds, until a chime sounds. Some newer models also need the top right button. Samsung stresses the steps are model-specific — your manual governs.
OF OF keeps coming back after I switch it off. Why?
Samsung's instruction is to repeat the steps until successful, after waiting a few moments to confirm the display has not returned to Cooling Off. If you are using another model's sequence, check your own manual — Samsung says the steps differ by model.
