LG Refrigerator FF Code: Meaning & Fixes
- Meaning
- Freezer fan error: the freezer fan motor isn't turning or sends no signal, usually because ice or frost has built up around it.
- Can I fix it?
- Sometimes, may need a pro
- Also shown as
- Er FF, E FF, FF E
- Seen on
- LG refrigerators with a digital display. Some analog models show the same fault differently; LG notes the code can look slightly different by model.
FF, shown as Er FF or E FF, means the freezer fan motor isn’t turning. LG says ice or frost around the fan is the usual reason, often from an overfilled freezer or a door left ajar. Fix it with a full defrost: unplug the refrigerator and leave both doors open at least 24 hours. If FF returns, request service.
Try this first
- Move the food to another refrigerator or an insulated cooler.
- Unplug the refrigerator and leave the freezer and refrigerator doors fully open for at least 24 hours.
- Put dry towels on the floor to catch the meltwater.
- Dry the interior, plug it back in and allow 24 to 48 hours to reach normal temperature.
- If FF returns, request service.
What causes FF
| Cause | What you notice | What to check |
|---|---|---|
| Ice or frost around the freezer fan | FF with frost on the freezer's back wall, freezer getting warm | Full defrost, doors open for 24 hours |
| Freezer door not fully closed | Frost near the door, FF after the door was left ajar | Door closes and seals fully |
| Overfilled freezer | Packages pressed against the back wall or vents | Leave space in front of the vents |
| Failed freezer fan motor | FF returns after a full defrost | Needs a technician |

-
Empty the refrigerator
Move food to another refrigerator or an insulated cooler so it doesn't spoil during the defrost.
-
Unplug and open the doors
Unplug the refrigerator and leave the freezer and refrigerator doors fully open for at least 24 hours. LG says it can take about one day in summer and up to three days in winter, depending on the ice.
Safety: Lay dry towels around the base and keep meltwater away from the outlet and power cord.
-
Don't speed it up with heat
Let the ice melt on its own.
Safety: LG warns that a hair dryer can warp plastic parts inside the refrigerator or create a fire hazard.
-
Dry and restart
Once all the ice has melted, wipe up remaining moisture, plug the refrigerator back in and allow 24 to 48 hours for the compartments to reach normal temperature.
-
Request service if FF returns
If the code is still there after defrosting, the refrigerator may need service.
When to call a technician
DIY ends at the full defrost. If FF remains or keeps coming back afterward, LG says the refrigerator may need service, since the fan motor or its sensor may have failed.
Questions people ask
Is Er FF the same as FF?
Yes. LG says error codes may be preceded by E, r or Er, so Er FF and E FF are the same freezer fan error.
What's the difference between FF and IF on an LG refrigerator?
FF is the freezer fan, which moves cold air through the freezer. IF is the ice maker fan, which moves cold air to the ice maker. Both are often caused by frost, but they point to different fans.
How long does it take to fix an FF code?
Plan for at least 24 hours unplugged with the doors open, longer in winter, plus 24 to 48 hours after restart to reach normal temperature.
