GE refrigerator ice maker leaking

I have a GE model GSH25JFXLBB refrigerator. The ice maker started overflowing leaving chunks of ice in the freezer. I shut the water to the ice maker off and cleaned out the freezer, using a heater to melt the rest of the ice. I turned the water back on to the ice maker and now the ice maker won't fill. The water in the door does work.
