SOURCE: MY LG REFRIGERATOR HAS AN ERROR CODE

You need to replace the iceing fan. Remove the cover on the back and you will see the fan.

SOURCE: lg lrfd22850sw frige code says ER FF. what does it mean! Please HELP!!!

I had the same error code. The problem was that the fan had frozen. I defrosted the fridge/freezer completely (it was ok for me cause I have a spare fridge). Your problem possibly is a frozen fan problem

Had the same problem + a weird noise, which turned out to be ice build up on the blower fan. Unplugged overnight and then opened the lower back panel. There is a small fan that blows over some small coils at the bottom of the box. There is also a drip pan that should be "full" of water. I sponged out the drip pan, put the panel back on and then plugged back in. Works great.

I emailed Miele and this is what they reply:

Thank you for your interest in Miele products. That message is a ice fault. If the ice has stopped production, please turn the toggle switch off under the electronic touch panel. To find this please reference the owners manual on pages 7 and 9. I have included the owners manual in case yours is missing. If your machine still produces ice fine just shake the cubes around making sure none are built up along the back wall of the ice drawer. If this continues please contact our service department. Please reference incident number 2698767 should you need to call in.
For more detailed information, please visit our web site at www.miele.com or to speak with one of our representative call 800-999-1360."

Haven't tried yet, but will post again if it didn't work, otherwise should be the answer

The control board is not seeing a feedback signal indicating that the freezer fan is running. Check for a build up of frost in the freezer compartment which may be preventing the fan blade from turning.
