Quick answer
Cooling Off / Demo mode.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so OFF may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
If a Samsung refrigerator shows **O FF**, the verified Samsung meaning in this research set is **cooling off / demo mode**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **O FF**. Search normalization stores it as **OFF** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
When the O FF condition is present, the display appears while the appliance is otherwise able to respond normally.
The O FF display becomes more meaningful if the message may be tied to a mode, test, reminder, setup state, or protective condition rather than a failed part.
One clue that supports the O FF diagnosis is that normal operation may resume after the documented mode or condition is cleared.
Depending on the exact model, o FF appears on the display while the appliance reports: Cooling Off / Demo mode.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
A safe owner-level check is to confirm the exact display characters and appliance model before treating the message as an issue.
The next non-invasive check is to check the user-facing setting, mode, door, filter, container, or setup condition named by Samsung for this display.
To rule out an accessible cause, use the model-specific manual to clear the status; avoid repeated resets if the message returns unexpectedly.
Before opening any service area, photograph the code before resetting or unplugging the refrigerator.
As an external check for O FF, check doors, visible airflow/ice obstructions, water/ice-bin seating, or demo mode only when relevant.
Before opening any service area, use the exact model manual because Samsung refrigerator codes vary by family.
Important safety warning. Protect food if temperatures are no longer safe. Do not open the sealed refrigeration system or energized inverter/compressor circuits. If resolving O FF would require energized internal access, that is the point to hand the diagnosis to a qualified technician.

When to request repair service
If the owner-accessible checks do not clear O FF, Service is not automatically required. Request diagnosis only if the status cannot be cleared as designed or normal operation does not resume. The repair should confirm the monitored function and its feedback before any board or component is condemned.

You can try the one reset Samsung documents for the model, but **O FF** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
The display can be normal in the documented context. If **O FF** appears unexpectedly, cannot be cleared, or prevents normal operation, then the issue deserves diagnosis.
The code alone is not enough to justify a part. **O FF** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Refrigerator O FF** separate from same-looking codes used by other Samsung appliance families.
