ok, so my refrigerator is a side by side. It has the temp display on the front with the ice and water dispenser. I have them both set at factory defaults so 0 in freezer and 37 in fridge. Fridge temp reads between 0 and -10 at times and the display is saying that it is 80 in the fridge which is wrong since I have a thermometer in there and it is about 18 to 20 degrees so everything is freezing. The fridge temp on the display fluxuates a couple of degrees up and down. Now would this problem be caused by the thermistor or that contol panel in the front?
