Freezer semi cold but fridge warm

Freezer semi cold but fridge warm Hopefully someone can figure this out with me. My GE GSH25JFXB model number fridge suddenly stopped cooling correctly. I have at this moment pulled out the back freezer panel and here is my findings. Freezer cool’s and has no ice build up on the coils as I replaced defrost heater a couple of years ago so all is good there. The bottom of the freezer is cold and some cool air makes it over to the fridge area but not enough to keep everything cold.
