The ice despenser is not working. It makes ice and dumps it to the bin. The water dispenser works fine. What items can only be causing the ice dispenser not to dispense ice?

Remove and replace light switch
Video makes it look easy. Kenmore refrigerator does not have "groove" along the right hand side of switch that allows for pushing down on release. Used a thin screwdriver to get under to push while holding switch edge with pliers. Kept slipping. Tape sides to avoid scratching inside of refrigerator.

Ice / water dispenser control panel cover discolored at bottom due to splashing water
I suggest turning off the water valve and power to the refrig before starting work. If this is not done the water dispenser will probably spray water down the front of the refrig. The whole icemaker assembly must be pulled out from the front. It is a friction fit--just insert fingers in the ice chute and pull out. The entire piece will pull out from the door. The control panel cover is held in by 8 screws that extend through the circuit board to the cover. It is a good idea to unplug the wiring to the circuit board when replacing the cover to prevent tension damage to the small guage wires. Once the new control panel cover is attached to the circuit board, the whole assembly can be reinstalled into the door.

The water dispenser lever came off, due to broken tabs in the door panel.
Before you begin, I'd recommend unplugging the refrigerator. You have to slip the putty knife in around the edge of the dispenser panel and carefully release the tabs all the way around and the entire panel pulls straight out. There are three wiring harnesses to unplug. You'll have to remove several screws and release the tabs around the electronic panel and remove it from the main panel. It's a good idea to take note or even pictures of how the ice and water actuators are positioned on the panel, so you get them situated properly on the new panel. If the ice actuator is not fit correctly on a knob that sticks up it may dispense ice all the time (happened to me). After you transfer the actuators to the new panel and the ice and water dispensing levers, you can re-attach the electronic panel on the left side. make sure all of the wiring harnesses are plugged in and the wires situated out of the way, then re-install the panel by pushing it straight back in. Plug the refrigerator in and test it out.
