If the display is telling you that the freezer is colder than it actually is, the problem is most likely electronic. Most modern refrigerators are computer controlled (silicon is taking over the world) In place of the old thermostat that directly turned on the compressor when it got to warm, New 'fridges have sensors that tell the computer what the temp is, and then the computer tells the compressor or circulating fans to come on or turn off as needed.
If the temp in the freezer rises too high, it turns on the compressor, and if the temp in the refrigerator side gets too high, it cirulates cold air from the freezer into it to cool it off. That's probably why the 'fridge side is cool enough, but the freezer side isn't.
If the sensor is telling the computer that the temperature is 0 degrees, it isn't going to tell the compressor to come on regardless of the actual temperature.
It is posible that the sensor is iced over, and therefore getting a flase reading, but my first guess on a new unit would be a bad sensor.
For what the opinion of a truck driver is worth....
(Oh, and be nice - save firm for when you need it.)
