The door in the Door-in-Door door

You have to open an extra door to get to the Door-in-Door shelves from the inside of the fridge. It's also the one part of the refrigerator that feels flimsy.

Tight fit

It's also a bit of a tight fit getting large items in and out of that top shelf.

Skinny ice maker

The ice maker is located entirely within the left door. That frees up space inside of the fridge, and the flat design does a good job of not blocking off the door shelves. It makes a little less ice than average, though.

Glide N' Serve drawer

The drawer at the bottom of the fridge glides in and out easily, and offers three separate temperature presets: Meat, Produce and Deli.

Default setting

Speaking of performance, here are the average temperatures in each section of the fridge when it's at the default setting of 37 degrees. The main body shelves were nearly perfect, and the drawers and left door did a nice job, too. The Door-in-Door compartment ran a bit warm, though.

Coldest setting

We repeated our tests at the coldest setting of 33 degrees F. Again, the fridge performed very well -- and this time, the Door-in-Door compartment fell below 40 degrees F. That's a good result.
