ice maker partially ejecting ice

This is my replacement of a replacement ice maker for my G.E. fridge. This unit is ejecting the ice out of the tray, but the rake stops turning with the ice sitting on top of it. The ice then freezes to the rake arm, keeping it from turning to perform another cycle until I physically remove the ice off the rake and it starts another cycle only to stop in the same position. Any ideas before I fix it with a 3lb sledgehammer? I’ve tried cycling it to no avail.
