Hi, I came across your post on the LG refrigerator fix for the ER FF code. I'm having the same problem, but I'm a little unsure of what exactly you're cutting. Do you think you give me a little more info on where you are cutting the insulation from?
Thanks,
Jim
I had this same problem, with the thing freezing up, and this is how I solved it -- I took everything out of the fridge, I defrosted it for a few WEEKS (yes, weeks), cleaned the thing thoroughly, replaced the water filter, and fired it up again. So far, it's been two months, the thing is quiet as a grave, and running like a champ.
I think if you let ice form around the condenser fan, it will not go away easily. I tried the hair dryer trick, the "unplug it for a while" trick, but nothing worked. After a week or so I'd hear that grinding sound (which I think was the condenser fan and a huge chunk of ice doing their thing).
This refrigerator doesn't like to be opened a lot, and it doesn't like a door being left open, even a tiny bit, at all. The right door of the refrig can stay slightly open without the annoying beep happening, and the bottom freezer can also be slightly ajar and the beep won't go off. It's a trick to get everyone in the family to pay attention to this and make sure that the doors are all closed TIGHTLY, particularly the freezer door.
I called up the (not terribly helpful) LG people and they denied a systemic problem with the frig, and they also denied that cutting insulation was a good idea.
I am not sure what the truth is, but so far, so good with the lengthy defrost. Of course, if you don't have a spare frig, or you're not prepared to live out of a cooler for many days (I do think you need several days to get that massive block of ice melted) to try this fix, you may not be interested in it.
