Here's GE's spin on the Door in Door refrigerator

LG and Samsung made door-in-door refrigerators popular, and now GE's jumping in with its own spin on the feature. Click through to learn more.

"Door in Door" just means that you can pull a trigger on the right door handle to open the front panel of the door instead of the door itself. That lets you access the in-door shelves without actually opening the fridge (technically speaking, at least).

In GE's door-in-door fridges, like the GFD28GELDS shown here, you'll also get a special shelf that rotates out of the fridge on a thick, sturdy steel plate.

You'll find a total of 27.8 cubic feet of storage space in this fridge, 18.6 of which are allocated to the fridge.

That leaves you with a fairly sizable 9.2-cubic-foot freezer.

The ice maker is packed entirely into the door with a flat design that doesn't block off any of the door shelves.

You'll also find the standard crisper bins and a deli drawer. That drawer doesn't offer multiple temperature settings like in other GE fridges, though, which is disappointing.

You can adjust the refrigerator's settings by tapping on a touch panel just above the ice maker.

Speaking of those settings, we spent weeks testing them out in our climate-controlled test chamber. At the refrigerator's default setting of 37 degrees, the entire Door in Door compartment ran warm.

Dialing down to the coldest setting got rid of the hot spots, but only just barely.

We ran the coldest-setting test a second time and replaced the regular door openings with Door in Door compartment openings. There was virtually no impact on performance.

Is that Door in Door compartment enough of a reason to buy this fridge? Read our full review to find out.
