Samsung Refrigerator OF OF: What the Display Means
Samsung Refrigerator code **OF OF** is associated with **cooling off / demo mode**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **OF OF**. Search normalization stores it as **OFOF** while preserving the characters a homeowner actually sees.

Quick answer
Cooling Off / Demo mode.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so OFOF 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
Samsung Refrigerator code **OF OF** is associated with **cooling off / demo mode**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **OF OF**. Search normalization stores it as **OFOF** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
When the OF OF condition is present, the display appears while the appliance is otherwise able to respond as expected.
When the OF OF condition is present, the message may be tied to a mode, test, reminder, setup state, or protective condition rather than a failed part.
Depending on the exact model, normal operation can resume after the documented mode or condition is cleared.
One clue that supports the OF OF diagnosis is that oF OF 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.
A safe owner-level check is to verify the user-facing setting, mode, door, filter, container, or setup condition named by Samsung for this display.
Before opening any service area, use the model-specific manual to clear the status; avoid repeated resets if the message returns unexpectedly.
To rule out an accessible cause, photograph the code before resetting or unplugging the refrigerator.
As an external check for OF OF, check doors, visible airflow/ice obstructions, water/ice-bin seating, or demo mode only when relevant.
As an external check for OF OF, 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. For OF OF, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.

When to request repair service
Service is not automatically required. Request diagnosis only if the status cannot be cleared as designed or normal operation does not resume. A repeatable OF OF event is more useful diagnostically than repeated resets, because it shows when the cooling off / demo mode check is failing.

Resetting can clear a temporary state, not a persistent issue. If **OF OF** comes back, preserve the code and move to the safe checks or model-specific service path.
Because **OF OF** is not treated here as a conventional component failure, service is not automatically required. Clear or complete the documented mode and confirm that normal operation resumes.
No. **OF OF** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
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 OF OF** separate from same-looking codes used by other Samsung appliance families.
