Fridge temp flashing 4

the fridge is freezing things and the temperature is flashing 4. I adjust the freezer temp to 0 and the fridge temp to 34, and within the seconds the fridge temp flashes 4. The control unit was bad and i replaced it, and since replacing, this has been occuring. Thanks!

I cannot be of much help here but perhaps running the diagnostics i will help.
