Product review (2 stars): Product doesn't work as expected out of the box ... seller issued a refund
Does not set temperature in refrigerator portion higher than 32F by default. I want to set it to the ideal temperature range of 35-40, but the item seller shipped me is incapable of doing this without knowing an undocumented trick, which they did not tell me. Adjusting the control up or down has absolutely no effect. And no matter how the Air Balance is adjusted, refrigerator temperature is still 32 MAX. Compressor runs a lot with this defective control. Freezer is -7F, measured with an accurate precision laser thermometer.

UPDATE: The seller says they are now out of stock of this item as of December 2016.  I later noticed a small hole with a screw adjustment inside, which turns out to be a course grain temperature control.  If you have one of these, (make sure the fridge power is OFF so you don't electrocute yourself) using a precision screw driver, the temperature can be set within an acceptable range of 35-40; however, doing this requires much patience, some sweat, and care.  There are no markings explaining what this screw is for, and no way to know how much to turn it to get the temperature you want, except by changing it repeatedly over time until you get it right.  It took me three (3) weeks to get the temperature set correctly doing this. One month later, it's still running the same temperature.

Getting a working part should not be so frustrating, I hope this helps someone.
