What to check first
Can I keep using it?
Do not keep using the appliance while this warning is active.
Do not rely on the refrigerator for perishable food while this warning is active or temperatures are outside a safe range.
- Safe next step
- Check actual compartment temperature, move perishable food to safe cold storage if needed, and use the model manual for any further steps.
- Stop when
- Food is thawing, temperatures are unsafe, the unit is not cooling, or electrical symptoms appear.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
Do not do this
- Do not keep running the appliance while this code is active.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Cooling Off, Demo, or Shop mode enabled
- Model-specific control-button combination activated
- Refrigerator intentionally configured for showroom display
Basic checks
- Match the complete display before acting; OF OF, O FF, OFF OFF, or scrolling temperature bars point to Cooling Off mode in Samsung's guide.
- Check both compartment temperatures and move perishables if they are warming; the refrigerator does not cool while this mode remains active.
- Find the exact model's control instructions; if its panel differs from Samsung's common layout, use only the documented button combination.
- After the mode is switched off, wait and confirm the normal temperature display returns; if the Cooling Off message reappears, stop repeating button sequences.
Reset or retry steps
- Do not power-cycle the refrigerator merely to clear OF OF; Samsung says service is not normally required and the mode should be switched off at the controls.
- For common external panels, Samsung documents holding the top two left buttons for 5 to 8 seconds until a distinct chime; some newer models also require the top-right button, so the model manual wins.
- Wait a few moments after the chime and confirm the display does not return to Cooling Off mode.
When to call a technician
- Contact Samsung support if the exact model instructions do not exit Cooling Off mode or the display returns after the correct button sequence.
- Request service if normal cooling does not resume after the mode is off or either compartment continues warming.
- Disconnect power and seek urgent help for smoke, sparking, a burning electrical odor, or a repeatedly tripping breaker.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
FAQ
What does Samsung Refrigerator code OF OF usually mean?
Samsung documents OF OF, O FF, and OFF OFF as a Cooling Off mode that disables refrigeration rather than reporting a fault. Model context matters: Samsung groups OF OF, O FF, OFF OFF, and scrolling temperature bars as Cooling Off, Demo, or Shop mode displays rather than separate failures.
Can I keep using the refrigerator with code OF OF?
Do not keep using the appliance until the visible issue has been checked and the relevant safety warnings have been addressed. Do not store perishable food in the refrigerator while Cooling Off mode disables refrigeration.
When should I call a technician for Samsung OF OF?
Contact Samsung support if the exact model instructions do not exit Cooling Off mode or the display returns after the correct button sequence. A qualified technician may check User-interface controls, Control electronics, and Temperature sensing system against the model's service information before treating any part as failed.
