Product review (3 stars): Seems well-made, but Danby doesn't provide good customer service.
Great refrigerator, BUT...

Danby provides poor customer service.  I got the run-around when my refrigerator wouldn't cool to the proper temperature.  I later learned (on my own) that there is a tiny screw on the side of the thermostat which controls the temperature range.  Turn it a tiny bit to the right for warmer, and left for colder.  (Right is clockwise; left is counter-clockwise.)  Be careful to turn the screw only a tiny bit.  Usually 1/8th to 1/4 turn at most.  Note this is the opposite direction than setting the actual temperature dial.

So...
If you turn your refrigerator to maximum cold, but it won't reach freezing, you need to access the thermostat and turn that little screw a tiny bit.  The same goes for getting too cold when on the warmest setting.  It's highly unlikely you need a new thermostat when it works, and only the range is wrong.
