Undercounter ice maker not letting in water

My Kenmore undercounter ice maker freezes ice but is not letting the water in to replenish the reservoir and release the ice block to the cutting grid. I replaced the water inlet valve but this did not correct the problem. I wanted to see if there is another part which could cause this malfunction. Could it be the freon temperature sensor? How could I test for this problem? Thanks.

What is the complete model number of the ice maker?
