Answer to "Why is my refrigerator not cooling?"I have had this happen to me three times, same refrigerator, upper & lower sides. It was the compressor the first two times and the computer board (supposedly) the third time. Now it does not cool at all. We are two for two with LG. Anyone who tells you that LG is a great refrigerator is a lier! Do your research first. Check out Complaints at the Better Business Burea. I have a $3800 paperweight that’s less than 3 years old. I spent over $1,400 to repair it and it still doesn’t work. I’ll never buy another LG product!!
