This unit only has a single control switch that supposedly adjusts the temperature in both the refrigerated section and the freezer section. The temperature is not consistent and ranges from 30.2°F to 38.6°F in the refrigerator section and -2.6°F to +6.8°F in the freezer section – this is when set on the # 4 setting (5 is coldest). I've used five different thermometers to measure these temperatures and they all give essentially the same poor results. The variations are just as erratic on the #3 or #5 settings. Cannot trust this unit to properly hold a desired freezer temperature of at least 0°F or a temperature in the refrigerator that does not go to below 32°F while trying to keep the freezer cold enough. BIG MISTAKE to purchase this unit!
