The symptoms are the freezer started to not freeze on the top shelf, but on bottom and sides were ok. Then we had a couple of hot and humid days and it seems that the refrigerator was not getting to max cold. It doesn't seem that the evaporator fan in the freezer is coming on. I cleaned under fridge and it was clean as was the condenser. The condenser and fan are working fine and I unplugged the fridge to reset it. Nothing seemed to help, but everything is working but just barely. If there is a problem with the freezer fan, thermostat, or heat exchange does that affect the fridge part too since there is only one condenser? Or is this more of a control or coolant problem.
