LG Refrigerator not running
If your LG refrigerator looks dead and the display and buttons do nothing, the most likely cause is a failed dispenser control board or a power issue. Start by checking the plug and outlet, confirm the circuit breaker or fuse is intact, and avoid using a ground fault outlet for a fridge. Next, inspect the dispenser control board and the user control and display board for burn marks or visible damage, since either board can fail and leave the refrigerator control panel not working or the refrigerator display not working. Also check the wire harness connectors between the panel and boards for loose or damaged wires, and try a simple power reset by unplugging the unit or switching the breaker off for a few minutes. The main control board is a less common culprit and should be replaced only after testing the more likely parts. If you need a replacement, enter your model number on RepairClinic.com to find the exact refrigerator control board, user control board, or dispenser control board that fits your appliance.
01 - LG Refrigerator Dispenser Control Board
If the refrigerator display appears completely dead, it's possible the dispenser control board has failed. You should inspect the board for any burn marks and replace it if it appears damaged.

Highly Likely
02 - Incoming Power Problem
Ensure plug is tightly pushed into a regular electrical outlet and the outlet is supplying power. Using a ground fault outlet for a refrigerator is not recommended. Confirm that no circuit breakers have tripped or fuses have blown.
Highly Likely
03 - LG Refrigerator User Control and Display Board
If the refrigerator display appears completely dead, it's possible the user control and display board has failed. You should inspect the board for any burn marks and replace it if it appears damaged.
Common
04 - Disconnected or Damaged Wire Harness
The wires from the control panel to the control board may be loose or have become disconnected. Make sure the wire harness connectors are tight. A damaged wire harness will need to be replaced.
Common
05 - Power reset
After a power surge or power outage, refrigerator operation could be temporarily affected. Full operation can sometimes be restored through a power reset by either unplugging the appliance's power cord for a few minutes and then plugging it back in or switching off the circuit breaker for the refrigerator then switching it back on.
Common
06 - LG Refrigerator Control Board
If nothing is working on the refrigerator, it's likely the control board is defective. However, this is almost never the cause. Before replacing the main control board, test all of more commonly defective parts. If none of the other components are defective, consider replacing the control board.
