OF OF
Samsung Refrigerator
Severity: MinorWhat Does This Error Mean?
OF OF is not an error — it means your Samsung refrigerator is in Demo Mode (also called Shop Mode or Showroom Mode). The fridge runs normally but the cooling is turned off. This mode is used in stores to display the fridge without running the compressor.
Affected Models
- RF28R6201SR
- RF23M8070SR
- RF23R6201SR
- Most Samsung French door and side-by-side refrigerators
Common Causes
- Demo Mode was accidentally activated by holding buttons during cleaning
- Demo Mode was set in the store and not turned off before delivery
- A child pressed multiple control panel buttons simultaneously
- A button combination was pressed while moving or setting up the fridge
- The fridge was purchased as a floor model with Demo Mode still active
How to Fix It
-
Look at the display panel on your Samsung refrigerator.
If it shows OF OF, O FF, or similar — Demo Mode is on and cooling is disabled.
-
Press and hold the Energy Saver and Power Freeze buttons at the same time for 3–5 seconds.
This is the most common combination to exit Demo Mode on Samsung refrigerators.
-
If that doesn't work, try holding the Fridge and Freezer temperature buttons simultaneously for 5 seconds.
Button combinations vary by model. Check your user manual for the exact steps.
-
The fridge should chime and return to normal temperature display.
The compressor and fans will restart. Allow 24 hours for the fridge to reach correct temperature.
-
If the fridge doesn't cool within 24 hours, there may be a separate fault.
Check the temperature settings and confirm cooling mode is active.
When to Call a Professional
OF OF is not a hardware fault and does not require a technician. If you cannot exit Demo Mode using the steps below — contact Samsung support. They can walk you through model-specific button combinations.
Frequently Asked Questions
Why is my brand new Samsung refrigerator not cooling?
If it shows OF OF or O FF on the display — it's in Demo Mode. The cooling is deliberately disabled in this mode. Turn off Demo Mode using the steps above. The fridge will start cooling within a few hours.
Will my food spoil if Demo Mode was on for a long time?
Yes — Demo Mode disables cooling completely. If food was stored while this mode was active, check it carefully. Perishables stored for more than 4 hours without cooling should be discarded.
How do I know if Demo Mode is on vs. a real error?
OF OF or O FF clearly indicates Demo Mode — not a fault. Real error codes show letters and numbers like 5 E, 22 E, or 40 E. If you see OF OF and the fridge is warm — exit Demo Mode first.
