I was able to pop the cap off the temp dial for this side by side and turn the set screw clockwise several times to raise the temp. (days of fine tuning though) The thermastat adjusts off of the freezer temp even though it is labled fridge. Now the freezer temp ranges from 38-58 as before and after the compressor kicks in. I had to turn the freezer dial to colder as this shuts the air vent from the freezer to the fridge. If it was open it would have to much of a temp range and this air would cause the fridge temp to fluctuate to much and would not be good for fermenting. The fridge ranges from 54-58 now.
