Lg Refrigerator Error Code: Er CF

Typically, this error code indicates that no feedback signal has been received from the condenser fan for more than 65 seconds.

This is caused by static electricity that might be trapped in the electronic control board.

Commonly known as flea power, this static electricity will cause erratic behavior on your device hence the error code.

In most cases, hard resetting the refrigerator usually gets rid of this issue. So, be sure to unplug your unit for at least ten minutes to clear out any erratic static charges still left in the control board.

In other cases, vacuuming the area around the condenser fan usually does the trick – the dirt and clogs might have been the cause.
