The LG refrigerator Er FR error code on the refrigerator’s display mainly indicates an abnormality with the refrigerator’s fan motor. This can be caused by a faulty refrigerator fan motor, wiring issue, or a faulty control board (PCB).

Troubleshooting Your LG Refrigerator With ER FR Error Displayed:
– Reset the refrigerator (unplug fridge for 10 minutes)

– Input unit to test 1 mode on PCB board (press button one time)

– Open freezer door and check air flow

– If no airflow, check fan motor for rust or ice (replace if rusty, iced up, or not easy to turn)

– If there is airflow, check the fan motor voltage from board
