LG Refrigerator (Side-by-Side) IF error code

Difficulty: Medium · Cost: $0–$200 · Duration: 8h

The IF error means your LG refrigerator has detected a problem with the ice maker fan. This code may also appear as F1 on some models. The ice maker fan circulates air to keep the ice maker at the correct temperature for producing ice. When frost or ice builds up around the fan blades it cannot spin freely and the unit displays this error. A manual defrost resolves it in most cases. If the error returns after defrosting and the doors and leveling have been checked the ice maker fan motor may need replacing by a technician.

Common causes

  • Frost or ice buildup around the ice maker fan blades preventing them from spinning
  • Door gasket is torn or not sealing properly allowing warm humid air to enter and cause frost
  • Refrigerator doors are not properly aligned or the unit is not level causing poor door sealing
  • Vents inside the refrigerator are blocked disrupting airflow
  • Ice maker fan motor has malfunctioned or failed

How to fix it

  1. 1

    Unplug the refrigerator and remove all food and ice from the ice bin

  2. 2

  5. 5

  7. 7

    Check the door gaskets for tears or damage especially on French Door models

  8. 8
