Maytag fridge warm freezer cold

A few days ago my ice/water dispenser stopped working and now the refrigerator is getting cool. The freezer is still cold and the fan is working. I’ve taken everything out so nothing is blocking the fans. So far I’ve done the following

  1. Removed the freezer panel and defrosted the coils. There was a little ice build up but not too bad. Put it all back together and still the same.
  2. Put it in service mode and tested the following
    Verified the fan works in both the freezer and fridge
    Verified the air flap behind the ice maker is working
    All thermistors seem to be working ok

Does this sounds like a control board problem? I hate to spend $300 to test the theory.

Thanks
