Why does wine freeze?
Temperature not being controlled. Checked the temperature while it was running; the digital display read 47 degrees, while a thermometer inside read 30.

Check for corrosion on the temp probe. The digital displays use thermistors to determine the temp so if the probe has dust on it it will change the resistance reading and tell the cooler that it is warmer than it is. All you can do is clean the probe, and if that doesn't solve the problem then the control or probe are faulty as they are usually one piece you will have to change it out. If you are mechanically inclined you can change out the temp control with an a19 abc24c remote bulb temp control from Johnson controls and that will last of the rest of your life.

Colin, thanks for your great suggestion. Now here is another possibility to consider. After posting my question, I decided to inspect the control board, just in case I needed to replace it. As soon as I got access to it, I was surprised to find that one of the wire bundles (5-wire, white w/red stripe) that plugs into the circuit board was firmly embedded by several sharp soldered pins that protrude from the back of the circuit board. I decided to install a thick piece of cardboard between the wire bundle and the circuit board, and then plugged the fridge back in. It has been working and controlling the temperature properly now for 2 days. If this turns out to be a coincidence, I'll try your suggestion, but to others out there, I would recommend that they look for a possible wiring short in the location that I had one. It was clearly manufactured with poor consideration of protecting it from shorts.
