A LG side-by-side freezer/refrigerator. It quits cooling a couple of days ago. When the problem happened, the temperature setting display also went out (partially for freezer and completely for refrigerator), and the buttons stopped working. Then I unplugged the unit, waited for about 24 hrs and plugged it back again. The unit appears to start cooling again, and the temperature setting also turned normal. However, within less than 12 hrs, the unit failed again. After the second failure, I simply unplugged and plugged it back without waiting, and the unit was back working again. So the unit appears to be working, but only for a limited time and then requires a reset somehow.
