Error Code R-1-4
Refrigerator compartment fan motor is not running or not reporting feedback
Moderate
Address soon - your appliance may not work properly
Also displayed as: R-1-4 (LED blink pattern on panel)
What This Means
Fan motor feedback signal line broken or poor contact; Motor winding failure; Motor wire separation or connector loose; Foreign object (ice) blocking fan blade
What actually causes this:
Ice build-up from a previous defrost failure can jam the fan blade, or the motor has worn out.
First Thing to Check
Listen for the fan running; open the fridge panel — if the blade is frozen, run a manual defrost cycle first.
Parts Involved
How to Fix
- 1
Select self-diagnostic function before powering off to confirm the error

Measure voltage between MAIN PCB REG1 Heater Sink and CN76 #4 (Orange) — should be DC 7–12V during operation
- 4
Measure pulse signal at CN76 #8 (R FAN) — should alternate 7–12V / below 2V
- 5
Check for ice or physical obstruction on the R-FAN blade
