Product review (5 stars): Wonderful!
A cracked shower drain above my kitchen resulted in a flooded kitchen and a non-working LG refrigerator. After a week of trying to find an LG repairman in my area, I was able to talk to one by phone. He advised me that the control board had probably gotten wet and shorted out. I checked, and there was a big black spot on the panel cover where the thing had blown. I took pictures of the old board as it was installed, so I'd have a guide to reconnecting wires. I ordered this one. It came super quick and I had it installed in less than 5 minutes. In a couple of hours I had a nice cold refrigerator and freezer.
Make sure to take a photograph before taking out the old board. While it's pretty obvious which wire goes where, there were two with similar connections. Having a photo to look at gave me more confidence as there are no directions with board. That's not a negative as you really don't need directions if you were able to take the old board out yourself.
