What to check, in order
- Reset the power first
Unplug the fridge, or switch it off at its circuit breaker, and use it again after about 5 minutes. If the code comes back, LG says ice may be stopping the fan.
- Get ready to defrost
Move your food to another fridge or an insulated cool box, and put dry towels on the floor round the fridge to catch any water.
- Unplug it and open the doors
Leave the freezer and fridge doors fully open for at least 24 hours. LG says it takes about a day in summer and up to three days in winter.
- Don't use a hair dryer
LG warns the heat can warp plastic parts inside the fridge or create a fire hazard.
- Dry it and restart
Wipe away any water left inside with a dry towel, then plug it back in and close the doors. Allow 24 to 48 hours for it to get back to normal temperatures.
- Stop it coming back
Don't overfill the freezer, and make sure the door closes fully every time.
When to call an engineer
If the code comes back after a full defrost, the fan motor itself may have failed. LG says to request a technician visit.
Good to know
- LG UK says to leave the doors open for at least eight hours; LG US says at least 24 hours, and up to three days in winter.
- Some top-freezer models show just F. Er rF (or E rF) is the same kind of fault for the fan in the fridge section: LG's advice there is the 5 minute power reset, then a technician if it comes back.
Parts people end up buying
Only if the checks above point to a part. Match it to your model number first: it's on a label inside the fridge, usually on a side wall, or on the back.

Quick answers
What does the LG Er FF error code mean?
The freezer fan can't turn, usually because ice or frost has built up round it. LG says this often happens when the freezer is too full or the door isn't fully closed, letting outside air in.
Can I fix LG Er FF myself?
Very easy (1 to 3 days, mostly waiting). Start with: reset the power first; get ready to defrost; unplug it and open the doors. If the code comes back after a full defrost, the fan motor itself may have failed. LG says to request a technician visit.
Is LG Er FF worth repairing?
Usually free. A full defrost usually clears it and costs nothing but time. If the fan motor has failed, it's a repair for a technician.
