How to fix LG er-ff — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Power reset the fridge
Unplug the fridge for 5 to 10 minutes, then plug it back in. If the error was a temporary stall, the fan may restart. - Clear blocked vents
Make sure food packages are not pressed against the vents on the freezer back wall. Blocked vents starve the fan of airflow. - Defrost the freezer
Move food to a cooler, unplug the fridge, and leave the freezer door open for about 8 hours. Ice on the fan motor is the most common cause, and melting it often fixes the code.Safety warning: Do not chip ice off with a sharp tool. Let it melt naturally and towel up the water.
When to call a technician
- The fan never runs even after defrosting
- You hear grinding or buzzing from the freezer wall
- The code returns within a day of clearing
- The freezer itself is warming up
Frequently asked questions
Why is my fridge warm but the freezer is cold with Er FF?
The freezer fan pushes cold air from the freezer into the fridge section. When it stops, the fridge warms up first.
Should I hear the freezer fan running?
Yes, a quiet hum when the doors are closed. No hum plus this code means the fan is stalled or dead.
Can ice really stop the fan?
Yes, it is the most common cause. Frost creeps onto the blades until they cannot turn, and a full defrost frees them.
