Question about Refrigerators
LG LRFC25750tt Er FF error- we already cleaned out fan. There was no ice buildup on the fan, cleaned off debris and dust. Plug it back in and it works for a few hours and then we get the error code again. Is it possible that this is still an issue with the fan or does this point to a motherboard issue? If it is more likely a motherboard issue is that something we can replace ourselves and how costly will it be?
My name is Peter. I am a retired field service refrigeration technician.
It is quite a task to get to the fan. Did you really remove the back wall and access the fan? If so good for you.
I doubt the problem is the mother board. The problem is your fan, it is starting to go. Accessing the fan is the hard part. Replacing the fan motor is the easy part.
The fan motor is about $50.00. Part number 4681JB1027H.

SOURCE: Error code ER FF
The error indicates the freezer fan is not functioning properly. The
fan supplies cold air to the refrigerator that is why it seems warmer.
The fan may be frozen, try unplugging it for a few hours to let it thaw. Also check to see if something may have gotten into the vent holes in the freezer that could be blocking the fan from turning.

SOURCE: Error Code ER FF
I had the same problem. I can tell you that simply unplugging the fridge and letting it defrost isn't going to work. You need to get take it apart.
I had the Er FF code about 2 months ago and let the freezer defrost for a couple hours and it started working again. Then two days ago I got the error again. This time I decided to get inside there.
First and foremost, UNPLUG the fridge and TURN OFF the water!
Next empty everything out of the freezer and start taking it apart. You have to get everything out of it to get that back panel off. This includes the ice maker and the rails that the drawers slide on.
Now that the freezer is completely empty there are two screws that hole the back panel on. In my freezer one is a white screw high in the center and one was a gold screw in the little panel that the ice maker hooked up to.
Next grab the back panel by the little fins on the top of it in the middle. Give it a good firm pull, but take care not to yank it too far... it's still connected by wires back there. When I pulled my panel out I found a HUGE chunk of ice on the top of the panel just to the right of the fan that feeds cold are to the fridge. Get that thing off of there taking care not to damage the foam insulation and watch those shiny metal fins that are behind the panel.
While you're putting it back together try to dry everything off as much as possible (I tried see the bright side of the whole evolution and realized I could really clean my freezer).
Once it's all put back together plug that baby in, turn on the water, and enjoy the next four hours as it gets back to being cold.
I'd say you need moderate tinkering skill to do this. If you only own one screwdriver and you never use it you should probably call someone.
Hope this helps!

ER FF is freezer fan motor failure code. this directs air into the fridge compartment from the freezer room. dead fan=warm fridge.

Error Code "Er FF" indicates a problem with the unit's freezer fan.
The freezer fan controls the temperature in the freezer. The source of this error is most likely ice buildup. As with the Er IF error, allowing the unit to thaw should resolve the issue. This can be caused by frost accumulation on or around the freezer fan. Unplug the unit for 3-4 hours to allow this to melt off. If error code persists, call Customer Service.
