Samsung fridge-freezer error codes
Samsung fridge-freezers flash an error code (for example 5E, 21E, 22E or 33E) when a sensor, fan or defrost system fails. Find your code below for meaning and safe checks.
| Code | Meaning | Severity | First action |
|---|---|---|---|
| 22E | Humidity / defrost sensor error | Often fixable at home | A humidity or defrost sensor is out of range; automatic defrost cannot be verified and ice may build up. |
| 33E | Ice maker sensor error | Often fixable at home | The ice maker sensor is faulty or the ice maker is jammed, so ice production stops or errors. |
| 21E | Fan error | Often fixable at home | A cooling fan is blocked or has failed, so cold air is not circulated. |
Safety first
Unplug before any check. Never open panels beyond the filter flap. Anything involving internal wiring, the heater or gas must go to a professional — see each code page for its "call a professional when" line.
