ABSTRACT:
A refrigerator with a freezer section and a passage for the flow of ice through the closed freezer section door is provided with a solenoid-like actuator which is effective for quickly opening a related ice dispenser door upon initiation of the flow of ice, and which is effective for relatively slowly closing the related ice dispenser door to thereby assure that further ice will not pass into the passage after the ice dispenser door is closed.
