Error code guide
Samsung refrigerators flash a number-and-letter code when a fan, sensor, heater or the ice maker stops working properly. Older models end the code in E and newer ones often end in C. Many of these codes are connected to ice build-up, which is why defrost and ice-maker problems are some of the most common Samsung fridge repairs we see.
| Code | Meaning |
|---|---|
| 21E / 21C | Freezer fan error — the control isn't sensing the freezer fan turning. |
| 22E / 22C | Fridge fan error — often after the door has been left open too long. |
| 5E | Fridge defrost sensor error. |
| 39E / 39C | Ice maker function error. |
| 40E / 40C | Ice room fan error. |
| 33E | Ice pipe heater error. |
| 84C / 83E | Compressor fault — 84C is a compressor lock; 83E is abnormal compressor current. |
| OFF / OF OF | Not a fault — the refrigerator is in Cooling Off (demo/showroom) mode and isn't cooling. |
Freezer fan error — the control isn't sensing the freezer fan turning.
When to call: Ice around the fan usually points to a defrost problem. A forced defrost only buys time — we fix the cause.
Fridge fan error — often after the door has been left open too long.
When to call: If 22E returns within days or weeks, the defrost system or fan needs repair.
Fridge defrost sensor error.
When to call: Left alone, the evaporator can ice over and the fridge will stop cooling. Needs a technician.
Ice maker function error.
When to call: If 39E keeps coming back, the ice-maker assembly or its wiring needs attention.
Ice room fan error.
When to call: One of the most common Samsung ice-maker repairs — we fix the seal or fan so it doesn't keep freezing up.
Ice pipe heater error.
When to call: A failed ice pipe heater lets the fill tube freeze, so the ice maker stops getting water. Needs a technician.
Compressor fault — 84C is a compressor lock; 83E is abnormal compressor current.
When to call: If the code returns, call promptly — the fridge may stop cooling. We test the compressor and inverter board before recommending anything expensive.
Not a fault — the refrigerator is in Cooling Off (demo/showroom) mode and isn't cooling.
When to call: No repair needed — but if the fridge still isn't cooling after leaving demo mode, call us.
Unplug the refrigerator (or switch off its breaker) for about 60 seconds, then restore power. A code that comes back means the fault is still there. Keep the doors closed while you wait, and check that the fridge stays at or below 40°F.
Codes vary by model and year. Check your owner's manual for your exact model — if a code isn't listed here, call us and we'll look it up.
