Freezer doesn't work properly. Not cold enough
My samsung upright refrigerator has the freezer in the bottom. It stopped working but the fridge part is working well. Actually the freezer becomes a fridge. Don't know why. We unplugged and kept it off for 24 hours, but problem still there. However, if we "power freeze", the freezer will work until we turn off "power freeze" button.
Not sure what to do by myself. Do I need to buy a new one?
