Kitchenaid refrigerator not cooling the top fridge but freezer works fine ? - kitchenaid refrigerator knocks

My KitchenAid fridge does not cool, but the freezer works without problems. My model is kbfa25erss01. What could be causing this? A technician came out and quoted to replace the fan motor EVAP, but the fan is running to be found. I'm confused.
