Common Samsung codes
| Code | Meaning | What usually causes it |
|---|---|---|
| OF OF / O FF | Cooling Off (demo) mode | Display mode turned on — lights and display work but nothing cools |
| 21E / 21C | Freezer fan error | Ice on the freezer evaporator fan, or a failed fan motor |
| 22E / 22C | Fridge fan error | Ice on the fresh-food evaporator fan — very common; usually a defrost or drain issue behind it |
| 5E / 5C | Defrost sensor error | Failed defrost sensor or wiring, often with ice buildup |
| 33E | Ice pipe heater error | The heater that keeps the ice maker fill tube from freezing has failed |
| 39E / 39C | Ice maker error | Ice maker cannot complete its cycle — frozen, jammed or failed module |
| 40E / 40C | Ice room fan error | Ice compartment fan blocked by ice or failed |
| PC ER / PC CH | Communication error | Main board and door or display electronics are not communicating — wiring, door hinge harness or board |
Code formats differ between model years. Newer models use a "C" suffix in place of "E" for the same fault. Your exact model's code list is on the tech sheet, usually behind the bottom front grille or inside the fresh-food section.
What to do when you see a code
- Write the code down before resetting anything. It helps the diagnosis.
- Check for OF OF first. If cooling is off, consult your owner's manual to exit Cooling Off mode — it is a button combination on the control panel, held for several seconds.
- Reset once. Unplug the refrigerator or switch off its breaker for five minutes, then restore power. If the code comes back, there is a real fault.
- Look for ice. Fan codes (21E, 22E, 40E) with grinding noise almost always mean ice is blocking a fan. A manual defrost clears it temporarily, but the cause — usually the defrost system or a drain — needs repair, or the code returns.
The 22E and 39E pattern
On many Samsung French-door refrigerators, two codes show up together over time: 22E (fresh-food fan blocked by ice) and 39E (ice maker failure in the door). Both come from moisture and frost in places it should not be. This is the most common Samsung repair we perform. See Samsung refrigerator repair and ice maker repair.
Frequently asked questions
How do I clear a Samsung refrigerator error code?
Power-cycle the refrigerator by unplugging it for about five minutes. If the fault is gone, the code will not return. If it does return, the underlying part still needs repair.
Is it safe to keep using my Samsung refrigerator with an error code?
Usually yes for a short time, as long as food stays at 40°F or below in the fresh-food section and 0°F in the freezer. Check with a thermometer. If temperatures rise, move perishables and call for service.
Does a Samsung error code mean the compressor is bad?
Rarely. Most Samsung codes point to fans, sensors, heaters or the ice maker. Compressor and inverter problems usually show up as poor cooling rather than one of the common codes above.
