Samsung 40E: Ice room fan error

The fan that circulates cold air through the ice compartment isn't spinning as expected. It's typically jammed by frost or a failed fan motor, which hurts ice making and cooling.

Most likely causes

  1. Frost or ice jamming the ice-room fan blade
  2. Failed ice-room fan motor
  3. Defrost fault letting ice accumulate
  4. Loose or damaged fan wiring
  5. Control board fault
Before you start — unplug the refrigerator before working on it. Mind sharp metal edges, and never open the sealed refrigerant system — compressor, sealed-system and refrigerant work must be left to a qualified technician.

Step-by-step fix

1Manually defrostUnplug the refrigerator and leave the doors open for several hours so any ice on the fan melts.
2Clear obstructionsMake sure no ice chunks or packaging are blocking the ice-compartment fan.
3Restore power and testPlug in, close the doors, and check whether 40E clears once the fan can turn.
4Watch for a repeatIf frost quickly returns, the defrost system may not be clearing ice properly.
5Call a technicianIf the code persists, have the fan motor and defrost components tested and replaced.

Still showing 40E?

If you’ve worked through every step and 40E keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.

Which models this applies to
