An LG refrigerator ice dispenser not working usually comes down to a few easy-to-check failures. Start by inspecting the dispenser door, because if the door or its linkage is broken it may not open to release ice. If the whole dispenser system is dead, the dispenser control board can stop power to the system, but if only one function failed test individual components first. Dispenser switches are a common culprit; test each switch for continuity with a multimeter and replace any that fail. If you don't hear the clunk when switching between crushed and cubed, the crushed/cubed ice solenoid may be bad. A faulty main control board can also cut power to the dispenser, and the ice chute itself may be jammed by clumped cubes; running warm water through the chute often clears obstructions. RepairClinic carries the parts you need for ice dispenser repair, and you can enter your model number on RepairClinic.com to find the exact replacement part for your refrigerator. These steps will get you from refrigerator not dispensing ice to fixed without guessing.
01 - LG Refrigerator Dispenser Door
The dispenser door is opened by a motor or a solenoid to dispense the ice, but if the door is broken, it may not open properly in order to release the ice. You should inspect the dispenser door for damage to determine if the component should be replaced. You may have to remove the dispenser control panel or frame to access and inspect the dispenser door.

The dispenser control board governs most of the functions of the dispenser system. If the control board is faulty, it may stop supplying power to the entire dispenser system. If only one dispenser part is not working, test each of the dispenser components before testing the control board. It is more likely that a single part has failed. If the entire dispenser system is not working, the control board is more likely to be at fault.
The dispenser switches send voltage to the dispenser. If one of the dispenser switches is defective, the dispenser will not work. To determine if a dispenser switch is defective, use a multimeter to test each switch for continuity. If a dispenser switch does not have continuity, replace it.
The crushed/cubed ice solenoid is the component that opens and closes a door in the ice bucket auger housing to allow the fully formed ice cubes to pass through or to divert the cubes through a crushing blade system to crush the ice when that option is chosen. If you don't hear a "clunk" sound when switching between the "Crushed" and "Cubed" ice options, it's likely the crushed/cubed ice solenoid is defective. You can use a multimeter to test the solenoid for continuity, a continuous electrical path present in the component. If the solenoid has no continuity, the component is faulty and will need to be replaced.
A refrigerator's main control board governs most of the functions of the appliance including the dispenser system. If the control board is faulty, it may stop supplying power to the entire dispenser system. If only one dispenser part is not working, test each of the dispenser components before testing the control board. It is more likely that a single part has failed. If the entire dispenser system is not working, the main control board is more likely to be at fault.
