Hi, my fridge seems to be running perfectly but it is not making things cold. In the morning it started freezing things in the fresh foods section and the freezer section was thawing all the food, so I adjusted the settings and went to work, It now is not cooling anything at all. There is no ice at all on the evaporator, bottom coils are clean, compressor is running, fan in freezer is working, If I turn the timer I can hear the fridge turn off during the short defrost cycle as expected. The fridge keeps running but does not get cold. What can I check next?
