Peter V Murrieta , CA September 12, 2015 Dead lg refrigerator/bad printed circuit board After reading many posts about LG refrigerators, I thought that I would try to replace the fuse on the printed circuit board (PCB) found in the back of the fridge. I successfully soldered off the old fuse and soldered a new one on. Sadly, however, that fix did not work. Plan B was to replace the whole PCB. I ordered the part here on appliancepartspros.com. It arrived next day, and the swap was quite easy--just a few connections to undo, and four clips to remove the old board. Reverse the process to put the new board in, and voile!, the fridge came back to life. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
