OF OF error code
Cooling Off mode
What does Samsung Refrigerator or freezer OF OF mean?
Cooling Off, Demo or Shop mode is enabled; this is not a product fault. Samsung uses OF OF to identify an operating or component condition on the affected refrigerator or freezer. The code is a diagnostic starting point rather than proof that one specific part has failed. Confirm the complete code, exact model number and region before using repair information or ordering components.
The code identifies the condition detected by the product; it does not always identify the failed component on its own. Confirm the full code and exact model before ordering parts or attempting a reset.
The Samsung Refrigerator or freezer OF OF error code indicates cooling Off, Demo or Shop mode is enabled; this is not a product fault. Samsung uses OF OF to identify an operating or component condition on the affected refrigerator or freezer. The code is a diagnostic starting point rather than proof that one specific part has failed. Confirm the complete code, exact model number and region before using repair information or ordering components. This guide explains what the code means, the symptoms and likely causes, the checks that are safe to make, and when to stop and arrange an authorised repair.
Symptoms you may notice
- The refrigerator or freezer displays OF OF and may interrupt its cooling cycle.
- Cooling, ice production or fan operation may be reduced or interrupted.
- The display may show the code continuously or after a power event.
- Cabinet temperature or unusual noise may indicate that the condition is still active.
- The precise behaviour can vary by model, software version and the point at which OF OF is detected.
Common causes
- Samsung Refrigerator or freezer OF OF is associated with the operating or component condition described in Samsung's guidance.
- The product has detected an operating value outside its expected range.
- An external condition, obstruction or installation issue may be contributing.
- A sensor, connection or component may not be responding normally.
- Internal diagnosis may be required if the code returns.
- The display code alone cannot confirm which cause applies; diagnosis should begin with the least invasive documented checks.
Before you start troubleshooting
Use the display, rating label or product menu to confirm the exact model. Similar-looking codes can have different meanings across product generations and regions.
- Record the code before disconnecting power because it may help diagnosis.
- Check accessible doors, vents and controls without dismantling the appliance.
- Protect temperature-sensitive food if cooling performance is reduced.
Troubleshooting steps
- Photograph or write down OF OF, the model number and what the refrigerator or freezer was doing when the code appeared.
- Read the Samsung guidance linked in the source field and check that it applies to the exact model and region.
- Record the exact code and the stage of operation when it appeared.
- Check the user manual for the exact model and region.
- Complete only visible, external checks that do not require dismantling.
- Restart once only when Samsung's instructions permit it.
- If OF OF returns, stop repeating resets and arrange authorised diagnosis with the recorded details.
Can you fix this error code yourself?
The safest next step depends on the exact model and the cause behind the code. External checks may help, but a returning fault needs professional diagnosis.
A successful reset is not proof that the underlying issue is fixed. If OF OF reappears, note when it happens and give that information to the service engineer.
Reset instructions
Record the code before changing any setting. Use a reset only when the exact Samsung guidance calls for it; otherwise leave the diagnostic information visible. If the code returns after one permitted reset, arrange service. A reset can clear the display without correcting the cause, so confirm normal operation afterwards and retain a record of OF OF for the engineer.

Contact Samsung or an authorised service provider if OF OF returns after the documented external checks, appears with leakage, smoke, overheating, electrical tripping, unusual noise or loss of a safety-critical function. Professional diagnosis is also required whenever testing would involve internal wiring, refrigerant, gas, high-voltage, sealed-system or moving components. Provide the full code, model number, serial details, region and the stage of operation at which the fault occurs.
