On many of the new french door models built by Maytag (that would include Kitchen Aid, Whirlpool, and Amana), there is a common theme where the produce freezes. The manufacturer is well aware of this and has designed a kit to correct the issue. The reason this happens is that the air from the freezer below the refrigerator migrates up into the bottom of the refrigerator and freezes the crispers. If the problem goes on long enough the water dispenser will stop dispensing water because the water tank behind the crispers freezes. To fix the problem, just thaw water tank with a hair dryer. Then order and install kit part number 12002776 and the issue will not come back.
This video explains how to remove the front face on a Whirlpool, Kenmore, and Kitchen Aid style refrigerator.
