What Is the ER dF Error Code?

The ER dF error code appears when there’s an issue with your LG refrigerator’s defrost system or temperature sensor.

  2. Temperature Sensor Problems: A faulty temperature sensor may send incorrect readings to the control board, causing the defrost system to malfunction and triggering the error.
  3. Wiring Issues: Loose or damaged wiring can also disrupt the operation of the defrost system and trigger the ER dF error code.
