I looked up online how to remove the Grid Cutter Assembly. It stated that if it still makes a sheet of ice, then the broken assembly is the problem. I removed the Grid Cutter Assembly and verified that the machine was still working, which it was.
I ordered a new Grid Cutter Assembly and it arrived in just a couple of days. I slid the new part in, re-attached the connectors, and the machine started making ice again.
