The freezer gets cold between 0 and 5 degrees at any setting 1 thru 6 However the compressor runs constantly I have turned it off unplugged it for 24 hours turned the control knob to 1 and plugged back in the temp gets down to between 0-5 degrees but again it never stops running
If the unit is only getting down to between 0 and 5 degrees, this is normal. If there is an issue with the unit it would be in the cold control. Where the unit is located can also cause the unit to run more often to maintain temps. Also check the evaporator to make sure that the evaporator coils have a full even frost pattern.
