Refrigerator ice maker overflowing (ice block in the bin)

Overflow usually means water entering when it should not: an inlet valve that seeps closed because of low pressure or debris, a fill tube that froze and diverts water, or a cracked fill tube. A tray that is not level or a misreading ice maker can also overfill.
