There is a part called a solenoid responsible for actuating a lever. This lever then opens a small hatch to allow ice to bypass the crushing mechanism. Either this solenoid failed and isn’t lifting the lever or it fell apart and needs to be put back together. The lever is a long metal rod that runs the length of the ice tray. It goes in to the rear of the freezer into a slot where a plastic piece is connected to the solenoid via a metal rod. The metal rod can easily fall apart if the ice tray isn’t removed correctly. The solenoid is an electromagnet that lifts the rod up and down. If the rod is in place and doesn’t lift up and down, check the wire connection to it. Make sure the lever rod is inside of the plastic connection. The plastic connection is just a square hole that rides up and down in a bracket. This should be the issue of a fridge not dispensing cubed ice.
