Refrigerator will not cool to 37
I have a 5 year old side by side Maytag and cannot get the frig to cool to 37. Best it will cool is 45. The freezer is at 0. I have defrosted the evaporator and there was frost but it was not to the point to restrict air flow. The evaporator fan seems to run okay with no noise but I tried spinning it and it will not spin like a squirrel cage motor fan. After defrosting no change. Freezer control is a 5 and frig at max or 9. I don't see any restrictions at the bottom or top of the frig. The small door at the bottom of the frig is flapping indicating cool air. Help!
