Samsung RF25HMEDBSR/AA-10 fridge displays 80F, inside fridge is ~20F; freezer is working fine

Refrigerator & Freezer Repair
1

Brand: Samsung
Model Number: RF25HMEDBSR/AA-10
Main Symptom: fridge displays 80F, inside fridge is ~20F; freezer is working fine
What happens & when: replaced fridge temperature sensor and control board, but fridge display is still at 80F and inside it is ~20F. Freezer is working fine for both display and inside temperature. Other recommendations are to check the temperature connector for corrosion; replace the display board or it could be the damper motor. It seems like it has something to do with the temperature connector and/or display board over the damper motor. Does the thermistor talk to the display first before going to the board or does the thermistor talk to the board first? Any help or suggestions are greatly appreciated.

Error Code (if any):
Parts or tests already tried: Replaced the DA32-10104N thermistor and the DA92-00592A (AP5914918) Ice & Water Main PCB Assembly for Bottom Mount Refrigerator (bought from Appliancepartspros)

The thermistor will talk to the main board and then the main board will send the information to the display board. This will most likely be caused by a faulty main control board.

Thanks for the reply. That says to me it is probably not the display. I swapped the main control board last night DA92-00592A (AP5914918)

Got home tonight and the fridge display is now at 35 F (the set temperature). Temperature was still around 20 F, but I opened the doors for a little while and the temperature is now around 32 F. I added 3 - 1 gallon water bottles that were around 60 F. Hoping this will cause the temperature inside the fridge to stabilize things and get it around 35 F overnight. It’s been about 18 hours since I swapped the board.
