For LG A FF error code indicates that the unit has detected an issue with the freezer fan. This can sometimes be caused by frost buildup.

change the evaperator fan motor ff means freeze fan motor

When the refrig is running, the fan in the freezer section should be blowing air. Check for frost build up preventing the fan blade from turning.

Er FF - Freezer Fan Error - This can be caused byfrost accumulationon or around the freezer fan. Unplug the unit for 3-4 hoursto allowthis to melt off. If error code persists, call Customer Service.

That is a freezer fan motor error, the freezer fan is no longer running. Check the freezer fan for a loose connection, if everything checks out ok there you probably need to replace freezer fan.

I'm no major appliance repairman. However, after reading several posts, I investigated the issue further since I received an ER FF on the front panel. I have a LFX25960SW refrigerator. I pulled the top and bottom baskets out, and was able to take the back panel out from inside. There was a solid block of ice built up around both fans and wires. I took a blow dryer and gradually melted the ice around the fans and wires. Then, as I was able, I pulled the remaining ice chunks off of the wires. I put the thing back together and it cleared the message. My wife says no more LG appliances for us. :)
