The Samsung RFG295AARS has twin cooling system. It has an evaporator in the freezer part and the refrigator part. The freezer is working fine. The food in the fridge department is freezing. no matter what I set the temperature on, it goes down to Approx. 30 degrees or below . I have replaced the control board twice, I have replaced the thermostat, I have replace the thermister. The digital panel on front of the fridge reads 46 degrees and it 30 degrees or less in the fridge department. I checked the evaporator, it is not frozen- appear to be operating properly. self diagnois read writeout shows -88 88. This is a mystery to me--any suggestions on what to replace next is most appreciated. This refrigator costs over $2500- I would like to keep using it.
