ER FF Hi - I have a 2 year old LG, LRBC22544st and it is showing ER FF. This is the 2nd time it happened in two days. (I unplugged it and plugged it back in to re-set) Since yesterday, the motor has been running very loud. The freezer hasn't been defrosting properly for say 6 months now. I have called LG on another problem (water line pinhole leaks) and they were completely out of hand, no help at all, just terrible! And, I don't have an LG repair person that will come out to where I live. What do I do? Any help would be greatly appreciated. I am getting desperate as it doesn't work at all now. Goes right back to ER FF.

Hi - Thanks for the reply. Yes, for one day the fan was really loud (between the first time it showed ER FF and the second time it showed ER FF). Now, it doesn't sound at all and the ER FF comes on right away after I unplug and plug it back in. I think it is burnt out. So, now I have the refrigerator off since last night. I would like to replace it myself if it is not too dificult. Hi - Thanks for the reply.

Ok, I will try it and let you know. Thanks! Ok, I will try it and let you know. Thanks!

Hi - I took out the shelves in the bottom freezer and I don't see a back panel. Unless it is the whole back panel of the freezer with one screw and the ice maker attached. Is this what I should remove? If so, should I remove the icemaker also, and the support bars that hold the shelves in place?

Hi - I had to remove the support bars, I cracked the back panel slightly, hope it is ok. Also chipped off a plastic piece that holds the support bars. And chipped off a piece of a vent. Anyway, when I pulled the panel off, there was big ice chunks, still melting from last night when I turned off the fridge, in the area of the fan. The fan could have been impeded by the ice chunks, thereby over-heating the fan's motor. Do you think this is a motor problem or something else caused this? I read another very recent post on the same problem and it mentioned something about a computer problem. What do you think?

Yes, fan motor no good now. Also, it was making a horrible noise, like an airplane taking off...for a day, 2 days ago.

What is an ADC problem?

According to Rascal Flat on Oct 27, 2006, the ice builds up because the faulty computer shut the fan off early in it's cycle and slowly the ice builds up and impedes the fan. Is this what you mean by an ADC problem?

ok, makes sense. After I take the fan/motor out, where do I find a replacement? And do I replace the ADC also? ok, makes sense. After I take the fan/motor out, where do I find a replacement? And do I replace the ADC also?

Where is the defrost heater and the defrost termination thermostat? I plugged refrigerator back in and it is running fine now, silent, fan is spinning, all seems fine.

Ok, thanks for everything. very helpful! Ok, thanks for everything. very helpful!

Hi again - I am still in the process with this fridge, I will gladly give you feedback when I wrap it all up. By the way, if I wanted to replace the ADC (defrost sensor), where would I find that on the refrigerator?

I would like to replace the ADC; I don't know where to find it on the refrigerator. If you know where it is on my fridge, please reply.

Thanks Krazytech, I am going to try and order the parts today. I think it is located in that access panel. Thanks Krazytech, I am going to try and order the parts today. I think it is located in that access panel.

To Catriver - Thanks for the great information. You don't know how much I appreciate it. I think you are saying that instead of replacing the ADC board, just ohm out the fuse and maybe my problems will be solved. I am a rookie when it comes to this stuff so I don't know what you mean about "ohm out". Actually, I don't know where the evaporator is either. I will hunt around for something that looks like the picture you provided. How to I "ohm out" the fuse? Do you think I can do this? I am not kidding, no one around here works on LGs. They all tell me that they recommend against buying them. One repair place told me to defrost it manually every six months and there is nothing else that they can do - LGs have defrost problems. Another place said they don't do LGs because it takes months for parts and you have to go directly through them. One place use to sell them; but they don't anymore because of all the problems. Sears told me that since I am out of warranty, I am on my own.
Anyway, thanks again. If I could find out what "ohm out" is and where that evaporator is located, I will try and do it myself.

Hi Catriver - First off, I understand the diagram you sent over. I have one of those ohm readers. Bad news is the front grill. When I take it off, I run into a white metal piece. no tech sheet. And to take the white metal piece off, I need to take the front levelers off that the fridge is resting on. there is a circuit sticker on the back of the fridge. And I have my user's guide but that doesn't show much of anything at all. My fridge only said ER FF. No defrost error. It didn't defrost properly though, for a year now. and there was those ice/frosty chunks blocking the freezer fan and causing my fridge to shut down in the refrigerator section.

Hi Catriver - I did as you said using the control panel. It seemed like both parts of the test went well. Display showed 222. The defrost heater sounded like it was on when it was displaying 222. I left it on for about 5 minutes and liquid started to drip down and sizzle. I didn't check the fuse in the harness yet...I will try and do that right now. I put the fridge back to normal mode now.

Thanks Catriver. So I don't need anything but to do what you recommend? Are you talking about the drain hose that hangs out near my icemaker? Thanks Catriver. So I don't need anything but to do what you recommend? Are you talking about the drain hose that hangs out near my icemaker?
