Fridge won't hold temperature settings, freezes on refrigerator side

I have a 14 year old GE Monogram side-by-side refrigerator that recently started freezing in the lower trays on the refrigerator side. I tried multiple times to adjust the temperature settings higher using the touch controls but will not hold. Temp on freezer side remains at 0; and on the fridge side 28 - 30 degrees. It is an old machine but as an ifixit person prefer to first repair. any fix recommendations or understanding of the problem is appreciated.

i came across the helpful tip (image attached, [image|846937] can't find the link), "expert Barry G" was right – it turned out to be a broken damper that was letting a continuous flow of cold air into the fridge section. i found a used damper on ebay for 28 dollars. fixed!

I also had this problem when we cleaned the fridge but did NOT put the climate control drawer back into the right position. Just the regular veg draw and that draw swapped spots. Then when a not vented draser is in lowest position it doesn't allow freezer air to circulate into that drawer but air movement pushes drawer open and then circulatets freezer air into the lower portion of the fridge freezing the lower half.

I had the same problem and decided to repair the broken door. I made a short video that shows how. https://youtu.be/1HooSxEUMkI

Chosen Solution

Cause 1

Temperature Control Thermostat

The temperature control thermostat directs voltage to the compressor, evaporator fan motor, and condenser fan motor (if applicable). If the temperature control thermostat is not working properly, it may cause the refrigerant system to run longer than necessary. As a result, the refrigerator will be too cold. To determine if the thermostat is defective, rotate the thermostat from the lowest setting to the highest setting and listen for a click. If the thermostat clicks, it is not likely defective. If the thermostat does not click, use a multimeter to test the thermostat for continuity. If the temperature control thermostat does not have continuity at any setting, replace it.

Cause 2

Thermistor

The thermistor monitors the air temperature and sends the temperature reading to the control board. The control board then regulates power to the compressor and evaporator fan based on the thermistor readings. If the thermistor is defective, the compressor and evaporator fan may run too frequently. As a result, the refrigerator will be too cool. To determine if the thermistor is defective, test it with a multimeter. The thermistor resistance should change in conjunction with the refrigerator temperature. If the thermistor resistance does not change, or the thermistor does not have continuity, replace the thermistor.

Cause 3

Temperature Control Board

The temperature control board provides voltage to the compressor and fan motors. If the control board is faulty, it may send continuous voltage to the compressor or fan motors. As a result, the refrigerator will be too cool. Control boards are often misdiagnosed—before replacing the control board, first test all of the more commonly defective components. If none of the other components are defective, consider replacing the temperature control board.

Glad you found the problem, but it's definitely not one of the common causes.
