Quick answer
40E on a Samsung refrigerator means the ice room fan motor has stopped or is not responding. Ice production will be affected.
What 40E means
The ice room fan circulates cold air around the ice-making compartment. Without it, the ice maker cannot maintain the required temperature for ice production. 40E appears when the main PCB detects the fan is not running.
How to fix it
- Unplug the refrigerator.
- Locate the ice room fan — inside the ice maker compartment, usually behind a small panel.
- Check for ice blocking the fan blades. Heavy frost in the ice compartment is a common cause.
- Spin the fan by hand. If stiff, the motor is seized.
- Check the motor connector on the PCB and reseat.
- Replace the fan motor if it does not spin when powered.
What does the 40E code mean?
40E indicates the ice room fan motor is not operating. Cold air cannot circulate in the ice maker compartment.
Common causes
- Ice buildup blocking the fan blades
- Seized fan motor
- Loose connector on the main PCB
- Fan motor failure
- Defrost issue causing recurring ice buildup

How to fix the 40E error
Access the ice room fan
Open the ice maker compartment and remove any panel covering the fan.
Clear ice
Defrost any frost blocking the blades.
Check the motor
Spin by hand, test for power. Replace if dead.
Fix the defrost system
If ice keeps returning, the underlying defrost cycle has a problem.
Safety first: Ice maker compartments have sharp edges. Wear gloves.
Part you may need: Ice room fan motor
If 40E keeps recurring after fan replacement, the defrost system is not clearing ice properly — check the defrost heater and sensor.
Frequently asked questions
40E stops ice production?
Yes — without the fan, the ice compartment temperature is uncontrolled and ice production stops.
40E vs 21E?
21E is the main freezer fan; 40E is specifically the ice room fan. Different components.
