The fridge controls come by way of an LCD touchscreen. When you slide the Keurig accessory in place, the coffeemaking screen will automatically pop up. Just select the size of your beverage, then tap "Next."
The brewer will take a few minutes to heat up. When it's ready to brew, this knob will glow red, and you'll give it a counter-clockwise turn to start the coffee pouring. If you want to speed things up, you can use a companion app to start heating the water remotely, or set it to heat up on a schedule each morning so things are ready to go as soon as you get out of bed.
Inside of the fridge you'll find 27.8 cubic feet of total storage space, along with a "TempSelectZone" that has its own thermostat. You can dial it to 32, 34 or 36 degrees F -- each of which is color-coded with LED lights that shine whenever you open the doors to remind you of what setting it's on.
Speaking of color coding, this heat map shows the average temperature of each region of the fridge during a 72-hour test at the default setting of 37 degrees (we dialed that TempSelectZone down to 32). Everything looks pretty good here, with temperatures below 40 degrees in the body of the fridge.
Here's the complete graph of that same test. Those spikes are our regularly scheduled door openings, which help simulate everyday usage. The fridge didn't have a problem keeping things down at a reasonable temperature.
We also tested the fridge out at its coldest setting of 34 degrees. Performance was, unsurprisingly, a little bit colder. We also brewed coffee twice a day during this test to see if it would affect the performance at all -- it didn't.
