Product review (4 stars): Temperature issue resolution.
This beverage refrigerator came with our new home.  I was having trouble get the temp down below 45 degrees (had the thermostat set at 36 degrees).  Customer service was of NO help so I performed the following and it worked like a charm:

1.  Made sure that the door gasket was properly seated all the way around the unit (I noticed that the door seal in a couple areas was not seated in the ridges properly and would cause cool air to escape and the unit to run constantly)

2.  Turned the unit off to see if the unit had ice build up.  The unit has a very small cup to catch the water as the ice melts.  This cup will fill so make sure it doesn't overflow or the water can damage the surrounding cabinets.  I used a towel to sponge the water up as the cup filled (I would estimate that I had >2 cups of water from the melted ice).  I kept the unit off for 24 hrs prior to turning it back on and made sure no more ice was melting from the unit.

3.  On initial start up with beverages inside, I set the thermostat at 40 degrees to allow the refrigerator to get down to temperature.  After 12 hours I set it to 36 degrees without any further problems.

With this unit in a cabinet that doesn't circulate air, I figure that I will need to perform these steps periodically.

Wanted to share my experience and how I resolved my temperature issue.  I hope this helps.  I give the unit 4 out 5 stars based on price and due to the fact that this issue can happen to other units if a gasket goes bad or a door is left open.
