Error Code FREEZER_FAN_ERROR

Q: What does error code FREEZER_FAN_ERROR mean on a Samsung refrigerators?

Freezer evaporator fan is not spinning Fan motor failure (mechanical or electrical); Bad wiring connection or open circuit at CN31-8/9; Fan blade blocked by ice accumulation; MAIN PCB relay or drive circuit failure; Rotation pulse feedback absent at CN31-7

Freezer evaporator fan is not spinning

Critical

Stop using immediately - risk of damage or safety issue

Also displayed as: F LED blinks

What This Means

Fan motor failure (mechanical or electrical); Bad wiring connection or open circuit at CN31-8/9; Fan blade blocked by ice accumulation; MAIN PCB relay or drive circuit failure; Rotation pulse feedback absent at CN31-7

What actually causes this:

The fan that circulates air over the freezer evaporator coil has stopped working, usually due to ice buildup or a failed motor.

First Thing to Check

Run forced defrost (Fd mode) for 5 minutes, then check if the fan spins freely without obstruction.

How to Fix

1
Enter test mode and verify compressor is running
2
Measure voltage between CN31-8 and CN31-9; should be DC 7~12V during operation
3
Check CN31-7 pulse signal (CN31-7 to CN31-9); expect ~2~3V AC with multimeter during rotation
4
If no voltage at CN31-8/9, check CN31-1/2 for 0V (door open signal)
5
Check CN31-1/2; normal closed-door reading is 4.5~5V
6
Verify door switch operates correctly
7
If voltage present but fan not spinning, fan motor has failed
8
If no voltage, replace Main PCB
