Hi Steve, I just replaced the board on my GE fridge, with Jeff's help. It's quite simple. Disconnect power, remove cover, disconnect molex plugs from old board, remove board. Put in new board, hook up plugs, replace cover, and plug 'er in! At least, that's how it was on my GE. I assume your LG will be similar. The board should be located on the back of the fridge, about waist high.
