Inside the fridge, you'll find a wide pantry-style drawer called the TempSelectZone with three temperature presets. The lights inside change color as you switch from one preset to another, then again whenever you open the doors thereafter, giving a subtle reminder of your setting.
All in all, the fridge boasts 27.8 cubic feet of storage space, 18.6 of which gets allocated to the fridge. I was able to fit all of our test groceries and stress test items inside, but it was definitely a bit of a squeeze.
The PFE28KMKES kept the body of the fridge below 40 degrees at its 37-degree default setting, but two of the the in-door shelves crept up into orange territory (the butter bin in the upper right gets a pass here -- it's meant to be a little warmer than the rest of the fridge).
