Turn Off Forced Defrost on a Samsung Refrigerator

Updated 5 November 2026 · Standard formula, shown below

Forced defrost is a service function that temporarily heats the refrigerator’s evaporator to melt frost; it is not the same as the normal automatic defrost cycle. How you stop it depends on the control panel and model, so check the model code before pressing buttons: the steps below cover common Samsung Family Hub and button-panel designs without assuming every model uses the same command.

What You’ll Need

Your refrigerator’s full model code, found on the product label inside the fresh-food compartment or on the appliance’s exterior label.
The owner’s manual for that exact model, if available. Samsung manuals can be searched by model code on Samsung’s support site.
A phone camera to record the control-panel display and button layout before changing a service setting.

Step-by-Step

Confirm that forced defrost is actually running. A service display may show a code such as “Fd,” but displays and labels differ by model. A warm interior, fan noise stopping, or water sounds alone do not prove the refrigerator is in forced defrost. If the display is showing a temperature or ordinary status screen, do not enter a service menu just to cancel a routine cycle.
Find the complete model code. Include every letter and number, including the suffix. Search the model code plus “user manual” or “forced defrost” in Samsung Support. Use the control instructions for that exact model family; a command shown for another Samsung refrigerator may open a different service function.
Check whether the panel is locked. If the display shows a lock indicator or the buttons do not respond, use the manual’s Child Lock or Control Lock instructions first. The unlock control and hold time vary. Do not hold an assortment of buttons to try to unlock it, because combinations may open diagnostic settings.
Use the documented cancellation method for your model. If the manual or Samsung support instructions identify a forced-defrost exit command, follow its exact button names, order, and hold duration. On some panels, a documented button combination exits the service function; other models require the control to be reset or the service function to finish. There is no safe universal key combination for all Samsung refrigerators.
Watch for confirmation. The display should leave the forced-defrost indicator and return to its normal screen, or the manual may specify another confirmation. Wait briefly and check that the refrigerator resumes ordinary operation. Avoid repeatedly pressing buttons if the display changes unexpectedly.
If the manual calls for a power reset, do it only as directed. First make sure you can safely reach the plug or circuit breaker without moving a heavy appliance or touching wet surfaces. Disconnect power only for the period specified by Samsung for your model, then restore it and allow the unit to restart. Do not use repeated power cycling as a substitute for the model-specific cancellation procedure.
Allow temperatures to stabilize. After leaving forced defrost, keep the doors closed and give the appliance time to resume cooling. The display may take time to reflect the actual compartment temperature. Check food and temperatures rather than judging recovery from a momentary display change.
Contact Samsung support if the command is unknown or the mode returns. Provide the full model code, the exact display message, and the steps already taken. Do not enter other service-menu options or alter sensor, fan, or temperature settings.

Common Mistakes

Copying a button sequence from a different model. Samsung uses multiple control-panel designs, and similar-looking buttons can trigger different functions. Verify instructions against the complete model code.
Treating normal automatic defrost as a fault. A refrigerator periodically warms the evaporator to clear frost. It should resume cooling; interrupting a normal cycle is usually unnecessary.
Assuming a code means the same thing everywhere. “Fd” is commonly associated with forced defrost in some Samsung service displays, but codes and their interpretation can vary by model. Confirm the display meaning in the correct documentation.
Holding buttons at random. Unverified combinations can enter diagnostics or change settings. Stop if the display presents unfamiliar codes or options.
Power-cycling repeatedly or too soon. A quick unplug may not cancel the mode, and repeated resets can make diagnosis harder. Follow the manual rather than trying multiple reset intervals.

Tips

Photograph the display and control panel before starting, and note the original settings if the manual says a reset may affect them.
Keep the refrigerator doors closed during recovery. Frequent opening adds heat and makes it harder to tell whether cooling has resumed.
If frost keeps building up, look for the underlying issue rather than repeatedly invoking or cancelling defrost. Check that doors seal and close fully, vents are not blocked, and food is not preventing a drawer or door from closing.
Do not chip ice with a knife or other sharp tool, pour boiling water into the appliance, or remove internal panels to reach a heater or sensor. Those actions can cause injury or damage.
For service, share the model code and any error or service-display code with a qualified technician or Samsung support.

Troubleshooting

The display will not change: Confirm the panel is unlocked and that you are following the exact instructions for your model. If the manual does not give a cancellation sequence, do not improvise; ask Samsung support whether the function must complete on that model.

The display changed to an unfamiliar code: Stop pressing buttons. Take a photo, note which controls you used, and consult the service or owner documentation for that model. Avoid changing settings whose purpose is unclear.

The refrigerator is still warm after exiting: Keep the doors shut and allow time for normal cooling to resume. Check whether the unit has power and whether its normal temperature controls are set as recommended in the manual. If cooling does not return, or an error appears, arrange service rather than repeatedly restarting it.

Forced defrost starts again: A recurring service-mode display may indicate that the mode was not exited, a control is malfunctioning, or the original command was misunderstood. Record when it happens and the display message, then contact Samsung support with the model code.

There is water after defrost: Some meltwater during a defrost process can be normal. If water leaks onto the floor or collects repeatedly, check the manual’s guidance and request service; do not dismantle the drain or heater assembly unless directed by a qualified professional.

Frequently Asked Questions

Can I turn off forced defrost on every Samsung refrigerator the same way?
No. Button combinations and service displays vary. Use directions for the exact model code rather than a sequence found for a different refrigerator.

Is forced defrost the same as the normal defrost cycle?
No. Forced defrost is generally a service or diagnostic function initiated through controls. Normal defrost happens automatically as part of ordinary operation.

Does “Fd” always mean forced defrost?
It is used for forced defrost on some Samsung service displays, but do not rely on the code alone. Check the documentation for your model.

Should I unplug the refrigerator to stop it?
Only if the model’s instructions or Samsung support recommend a power reset. Unplugging is not a universal cancellation method, and repeated resets are not advisable.

Will cancelling forced defrost damage the refrigerator?
Following the correct model-specific exit procedure is the sensible approach. Avoid undocumented button combinations or changes to service settings; contact support if you cannot confirm the procedure.

What if the refrigerator keeps entering forced defrost?
Record the model code, display, and when the behavior occurs, then contact Samsung support or a qualified appliance technician. A recurring issue may need diagnosis rather than another cancellation attempt.
