What is the function of the Articulation Mullion? How does it really work?
ANSWER Hello Di-Anne,
The articulation mullion keeps the "flapper" between the doors from getting cold enough to sweat. This prevents rusting of the appliance and also prevents water from running down and puddling in the floor. It works by heating the strip enough to prevent humidity in the room air from condensing on the strip.
