Samsung Refrigerator Error Code 21E
The control is not sensing the freezer fan turning, most often because the fan is frozen up after a door was left open or a gasket gap let moist air in. Defrosting clears most cases; a code that returns points to the fan motor.
Common causes
- Ice and frost buildup has frozen the fan in place
- Door was left open, or the door gasket is not sealing, letting moist air in
- Freezer evaporator fan motor has failed
- Fan wire harness connection is loose
What to check, in order
- Check the doors close fully and the gaskets make contact all the way around; clear anything packed tight against the freezer's rear wall vents.
- Defrost the unit: unplug it and leave the doors open for a few hours so ice melts off the fan, which is Samsung's suggested first fix for this error.
- Plug the fridge back in, close the doors, and listen for the freezer fan while giving the freezer time to pull back down to temperature.
- If the code returns, unplug the fridge and check the freezer fan's wire harness connection; a fan that still will not turn needs a new fan motor.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code 21E, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
Parts that may be involved

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
