Product review (1 stars): KitchenAid wine refrigerator doesn't cool much
With the temperature control dial set to maximum cooling, and the ambient room temperature at 67 F, the coldest temperature inside the (empty) unit is 56 F after waiting 48 hours.  There is no relationship between the temperature control knob and the interior temperature.  The appliance store is telling us that this is somehow normal but we're asking the builder to bring the unit back to the store.
