My Maytag refrigerator (MRT311FFFZ00) is freezing food in the refrigerator section on the lowest setting. I originally had a problem with the freezer section icing up. I had a certified repairman out and they replaced the thermistor in the freezer which resolved that problem, but then the refrigerator section was too cold, so they replaced the thermistor in the refrigerator section. They were out three times, and the refrigerator is still freezing food. After being fed up with them, I replaced the control board and thermistor in the fridge with genuine factor parts, and it is still freezing in the fridge section on the lowest temperature setting. I called Maytag which was totally useless. I did tell them this would be my last Maytag appliance. I have always bought Maytag before with no issues. The fridge is approximately 4 years old (out of warranty of course).
