Error Code FREEZER-FAN-ERROR
Freezer fan motor is not running or not sending feedback
Moderate
Address soon - your appliance may not work properly
Also displayed as: F blinks (freezer fan error — CN20 item 21 in self-diagnosis list)
What This Means
Failed BLDC freezer fan motor; Blocked fan blade (ice accumulation or foreign object); Disconnected or broken wiring to fan motor; Fan supply voltage low (should be 7–12V DC on CN20 pin 16 to pin 18); Main PCB relay or driver failure
What actually causes this:
The fan that blows cold air off the evaporator coil is stuck or burned out — without it neither compartment cools properly.
First Thing to Check
Listen for fan noise; if absent, open freezer and check the evaporator cover area for ice buildup blocking the fan.
Parts Involved
How to Fix
- 1
Execute manual operation (forced run) mode via Fridge + Power Cool held 6 seconds, then press Power Cool
- 2
With compressor running, measure voltage between CN20 pin 16 (S/RED) and CN20 pin 18 (W/BLK) — should be 7–12V DC
- 3
If voltage is present but fan does not spin, check for ice blockage around fan blade
- 4
If voltage alternates between 7–12V and below 2V, the motor is trying to start but is stalled — clear obstruction or replace motor
- 5
Measure pulse signal on CN20 pin 14 (PNK) with a multimeter — should read ~2–3V average (pulse signal)
