Our LG fridge is probably around 5 years old or so and it quit one night. We transferred all our fridge/freezer items to a fridge we have in the garage. My husband researched it and found that sometimes it's this control board that goes bad so instead of calling out a repair man or getting a new fridge, my husband ordered this and replaced  the old one, installed it on the back of the fridge and that did the trick. He said it wasn't hard to do and fridge is working fine!
