Make sure Forge’s ice shelves are installed correctly. Install the shelves so that the larger holes are closest to the ice maker door.
Make sure the black flaps behind the lower ice shelf are closed; they may be frozen open. Reset the flaps by pressing them closed if they are open before making ice.
The white float switch in the front right corner of Forge’s water reservoir may have become frozen. Gently pull the top of the float switch up to resume normal ice making.
If you suspect the ice gems are in Forge’s ice-making section and should have already dropped, run a cleaning cycle to release the gems. Discard any ice if a cleaning solution is used.
