The control does not detect the freezer fan turning. Samsung lists two usual causes: the fan has frozen because a door was left open or a gasket has a gap, or the fan motor has failed.
Likely causes
Listed from most to least common.
- Freezer door left open or not fully closed, so ice formed around the fan
- Gap in the freezer door gasket
- Freezer packed so full that the door cannot close
- Freezer fan motor failed
How to fix the 21E code
Unplug the refrigerator or switch it off at the breaker before removing any panel or filter.
Step 1: Check the freezer door
Make sure nothing is stopping the door closing. Do not pack the freezer so full that the door cannot shut.
Step 2: Check the gaskets
Look for gaps, tears or folds in the door gasket all the way around. Clean it with warm, soapy water.
Step 3: Defrost the unit
Move food to a cooler, unplug the fridge and leave the doors open for a few hours so any ice around the fan melts. Put towels down for the water.
Step 4: Restart
Plug the fridge back in, close the doors and let it cool for several hours before putting food back.
You'll need: Towels, cooler.
Parts that may need replacing
Check your model number on the label inside the door or on the back before ordering.

When to call a technician
If 21E returns after defrosting and the door seals well, request service. The fan motor needs testing and replacing behind the freezer panel.
A typical repair for this code costs $200–$400 in the US, including parts and labor. Prices vary by area and model.
Models this applies to
- French door refrigerators (RF series)
- Family Hub refrigerators
- Side-by-side refrigerators (RS series)
- Top and bottom freezer refrigerators (RT and RB series)
Codes can differ slightly between models. Your owner's manual is the final word and is available from Samsung support.
Common questions
›Can I still use the freezer with 21E?
For a short time. Without the fan, cold air does not circulate well, so the freezer can warm up. Check food temperatures.
›Why is my Samsung freezer making a clicking or scraping noise?
Ice may be building up around the fan blades. This often comes before a 21E code.
