Error Code F_FAN_ERROR

Q: What does error code F_FAN_ERROR mean on a Samsung RF28T5021B1?

Freezer fan motor not running or lost RPM signal Fan motor mechanical failure or jam; Bad connector contact at CN20 pin 14; Missing or weak pulse signal from fan motor; Ice blockage restricting fan rotation; Wiring disconnection; MAIN PCB relay failure

Freezer fan motor not running or lost RPM signal

Critical

Stop using immediately - risk of damage or safety issue

Also displayed as: F FAN ERROR

What This Means

Fan motor mechanical failure or jam; Bad connector contact at CN20 pin 14; Missing or weak pulse signal from fan motor; Ice blockage restricting fan rotation; Wiring disconnection; MAIN PCB relay failure

What actually causes this:

The freezer fan is either stuck by ice or not receiving power signal, preventing cold air circulation to the freezer

First Thing to Check

Listen if fan runs; check for ice blockage; ensure room is warmer than 66F

How to Fix

1
Check CN20 connector insertion at pin 14 (PNK)
2
Verify DC 7-12V supply to fan motor at CN20 pins 16 (S/RED) and CN20 pin 18 (W/BLK)
3
Listen for fan motor rotation
4
Measure pulse signal at CN20 pin 14 (should toggle with motor rotation)
5
Manually check fan for ice or obstruction
6
Check room temperature (must be above 66.2F/19C for normal operation)
