When plugged in the compressor would run and the temps on the front would drop to where they were set. But once there the compressor would stop running. The temp inside the unit would increase but the display still stayed at 0 and 38. If I unplugged and replugged the unit the temps displayed would read what actual temp was and the compressor would kick on and start the cycle all over. I was sure it was the control board so I replaced that. Nope, it wasn't the control board. By this time I had done more studying into the problem and with the help of Appliance Parts Pros narrowed it down to temp sensors and defrost thermal fuse. I found out I could perform measurements from the control board. I found the thermal fuse in the freezer section open. I replaced defrost thermal fuse and the temp sensor and I now have a working refrigerator.
