Fridge is not cooling - Just the fridge part - Freezer still works fine. On the left it reads -4 on the right 1 It should be 36. It just does not want to go up. I tried several functions to get the fridge working but - nothing seems to work: I unplugged the unit, left for a minute or so. Turne it on again. Set up the temperature to -4 and 36 and pressed Power Cool.
