Shortly after purchasing my Maytag refrigerator had to pay for a new motor in the ice maker. The cover for the lower large food tray broke. Now approx. 4 years later am getting ice build-up on the bottom of the lower freezer unit, about one-half inch thick. It is enough so the freezer door won't seal when it closes and the inside builds up with frost. Not happy with Maytag or this refrigerator.
