Here are the average temperatures in each region of the fridge from that same test. You can see that the bottom shelf is the coldest part of the fridge, but in general, everything is colder than it should be. In most cases, fridges aim for 37 degrees at the default setting.
Things obviously get even colder when you crank the fridge down to its coldest setting, which we did. I was surprised just how cold it got, though. The entire body of the fridge sits well below 30 degrees.
