My mother-in-law's GE Refrigerator model GSS25WTI CC ice maker keeps trying to make ice when full. It has a plastic arm that gets stuck in the 1/2 way "out" position. We can hear it making a buzzing noise about once a second, like it's trying to cycle. Anyone seen this problem? Seems like a bad design to me. I don't see how the plastic arm could be counted on to reliably be pushed back by filling ice.
