Er FF
LG Er FF on a refrigerator: freezer fan not working
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
LG says Er FF appears when ice or frost stops the freezer fan from turning. LG's fix is to unplug it and leave both doors fully open for at least 24 hours so it melts.
Safety first
Stop and check this first
- A fan code does not point to the refrigerant circuit. If anyone proposes opening that circuit, it must be a technician certified for refrigerants, backed by measurements.
- Do not use a hair dryer to speed up defrosting: LG warns the heat can warp plastic parts or create a fire hazard.
Safe checks you can perform
- Power reset
- Food out and towels on the floor
- Defrost with doors open
- Freezer load and door closing
Leave these tasks to a qualified professional
- Do not attempt this professional task: Check the freezer fan motor
- Do not attempt this professional task: Find why the ice formed
What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Check the freezer fan motor
What they doThe technician measures the motor and its connection with a multimeter and checks whether it turns freely.
They must show youthe measurement against the manufacturer's specification.
In writingthe cause and the part number if replaced.
Find why the ice formed
What they doThe technician inspects the freezer door closing and gasket.
They must show youthe gasket or closing corrected.
In writingthe work done and a test run without the code.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

What it means
LG explains that Er FF, E FF or F mean the freezer fan motor is not operating properly, usually because ice or frost around it stops it turning. It often happens when the freezer holds too much food or the door is not fully closed, letting outside air in. LG also suggests resetting power for about 5 minutes. If the code remains after defrosting, it may need service: the motor, its wiring or the board can only be separated by the technician's inspection.
