LG Refrigerator control panel not working
If your LG refrigerator control panel is not working, start with a few quick checks and the most likely causes so you can narrow the repair. The user control and display board is the top failure point, so press the buttons to see whether some work and check for power to that board; if it has power but won’t respond, the control/display board often needs replacing. Next likely is the dispenser control board, especially when the whole dispenser system is dead; test individual dispenser parts first since a single failed component can mimic a control problem. The display board itself can also fail, and loose or damaged wire harness connectors between the panel and control board are a common and easy fix. On models where the controls are built into the dispenser front panel you may need the full front panel assembly. Don’t forget to confirm incoming power to the outlet and breaker. For straightforward refrigerator control board troubleshooting and to get the right part, enter your model number on RepairClinic.com to find the exact replacement for your fridge buttons or display.
01 - LG Refrigerator User Control and Display Board
To determine if the user control and display board is defective, try pressing the buttons on the control panel. If some of the buttons work, but others do not work, the user control and display board might need to be replaced. Additionally, if the display is not working, check the power to the user control and display board. If the user control and display board has power, but it isn’t working, replace it.

02 - LG Refrigerator Dispenser Control Board
The dispenser control board governs most of the functions of the dispenser system. If only one dispenser part is not working, it is probable that an individual part has failed. In this case, test each of the dispenser components before testing the control board. If the entire dispenser system is not working, the control board is more likely to be at fault.

03 - LG Refrigerator Display Board

Additionally, if the display board is not working, check for power to the display board. If the display board has power, but it isn’t working, replace it.

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.

05 - LG Refrigerator Dispenser Front Panel
On some refrigerator models the user controls are part of the ice and water dispensers front panel. If none of the control panel buttons are working, it's probable the main control board is malfunctioning. However, if some of the buttons on the control panel are still functioning, it's more likely the unit's user control and display is faulty. If this component is sold as part of the dispenser front panel, the entire assembly can be replaced.
Highly Likely
06 - Incoming Power Problem
Ensure power cord is fully inserted into a regular electrical outlet and the outlet is supplying power. Check fuses or circuit breaker if needed. It is best to keep the refrigerator on it's own dedicated circuit and not to use a ground fault receptacle which can interrupt power to large appliances.
Highly Likely
