A refrigerator ice door mechanism having improved structure for controlling the outlet opening of a delivery chute provided for deliverying ice pieces from an ice maker within the refrigerator to an access space in the front of the door with minimum opening of the outlet. The closure is continuously biased to a closed position while permitting ice pieces moving through the ice delivery chute to move the closure away from the opening in passing to the access space. A time delay device is provided for applying a sealing force to the closure to sealingly close the opening a predetermined period of time subsequent to termination of the ice piece delivery operation.
