Samsung refrigerators 21E error

The freezer fan is not providing the expected rotation feedback.

21E

What this code can mean

Samsung associates 21E with a freezer fan that may be obstructed by frost, a door or gasket that has allowed warm air inside, or a fan motor fault.

Safe first checks

  1. 1
    Confirm the freezer door closes completely and the gasket contacts the cabinet all the way around.
  2. 2
    Rearrange food that prevents the door from closing without touching internal fan components.
  3. 3
    Protect temperature-sensitive food and use Samsung support if defrosting or service is required.

Possible causes

  • The freezer fan is restricted by frost or ice.
  • A door was left open or a door gasket is not sealing completely.
  • The freezer is packed so tightly that a door cannot close correctly.
  • The fan motor may require service.
Stop conditions
  • Do not remove internal panels or chip ice away from the fan area.
  • Request service if the code remains after visible door and gasket issues are corrected.

Use Samsung support or an authorized servicer when 21E persists or the fan cannot operate normally.
