LG Refrigerator Error Code Er FF — What It Means & How to Fix It

What Does This Error Mean?

The Er FF error means the freezer fan in your LG refrigerator is not working. This fan circulates cold air throughout the freezer compartment. Without it, the freezer and fridge temperatures will rise.

Affected Models

LRMVS3006S
LRFXS2503S
LFXS26973S
Most LG French door and side-by-side refrigerators

Common Causes

Ice or frost buildup blocking the freezer fan blades
Faulty freezer evaporator fan motor
Disconnected or damaged wiring harness to the fan
Failed defrost system causing excessive ice around the fan
Main control board malfunction not powering the fan

How to Fix It

Move frozen food to a cooler or a neighbor's freezer to prevent thawing.

The freezer will warm up without the fan. Protect your food first.
Unplug the refrigerator and leave the freezer door open for 8–12 hours.

Place towels on the floor to catch melt water. This thaws any ice on the fan.
After defrosting, check the fan behind the rear panel inside the freezer.

Try spinning the fan blade gently by hand. It should turn freely.
Plug the refrigerator back in and listen for the freezer fan to start.

Open the freezer door and press the door switch. You should hear the fan running.
If the fan does not start, the motor needs replacement by a technician.

Do not continue using the fridge without a working freezer fan.

When to Call a Professional

The freezer fan is critical for keeping food frozen. If defrosting does not fix the error, contact LG support or a technician. Expect repair costs of $150–$300 for a freezer fan motor replacement. Do not wait too long — rising temperatures can spoil food.

Frequently Asked Questions

How urgent is the Er FF error on an LG refrigerator?

Fairly urgent — the freezer fan keeps both the freezer and fridge cold. Without it, temperatures will rise within hours. Move perishable food to a cooler and address the issue quickly.

Is the freezer fan the same as the ice maker fan?

No — they are different fans. The freezer fan (Er FF) circulates air in the main freezer compartment. The ice maker fan (Er IF) only cools the ice maker area. The freezer fan is more critical for overall cooling.

Why does ice keep building up on my LG freezer fan?

Recurring ice buildup usually means the defrost system is failing. The defrost heater, defrost thermostat, or defrost timer may be faulty. The fridge should defrost automatically several times a day. If ice keeps returning, have the defrost system inspected.
