Our GE refrigerator is about 5 yrs old, everything works fine except once awhile, the water dispense tube freeze up & I have to blow hot water into the tube to unfreeze the water. But two weeks ago, after we came back from one week of vacation, there seemed not making ice. After I took out the ice tray & cleaned up, ice maker was making ice again. But it only dispenses crushed ice, not cubes. It looked like the solenoid was frozen & not lifting the front cover. When I cleaned the tray, I did manully push up the solenoid. But this time, I couldn't push up any more.
Could the solenoid frozen? Or maybe bad & need to replaced? How can I check? What's the part number?

Thanks.
