LG refrigerator display not working

Why is the display on my LG refrigerator not working?

Lack of power, a defective electronic control board or failed user interface component can prevent the refrigerator display from working.

Check for Power

When the display is blank on your fridge, check to see if the appliance has power.

If you don’t hear the compressor or fans running, open the refrigerator door to see if the interior light turns on.

If the refrigerator is completely dead, follow these troubleshooting tips to restore power to the fridge.

Check the house circuit breaker

Reset the house circuit breaker for the refrigerator. This will restore power to your fridge if the breaker was tripped.

If the breaker trips right away after resetting it, schedule refrigerator repair service to have a technician examine the fridge. An internal short circuit in the refrigerator may be causing the breaker to trip. You’ll need to get that short fixed before continuing to use the refrigerator.

Test the electrical outlet

Plug a nightlight or small appliance into the outlet for your refrigerator to see if it has electrical power.

If the electrical outlet is dead and the breaker isn’t tripped, you’ll need to have an electrician fix the outlet for the fridge.

Examine the power cord

Unplug the refrigerator and check the power cord for damage. If the power cord is cut or damaged, replace it.

Schedule refrigerator repair service

If you’re not able to find the cause of the power problem in your refrigerator after following these basic troubleshooting steps, you’ll likely need to have a service technician fix the fridge.

The technician will check the control and wiring to determine the cause of the failure.

Reset the Control Board

If the refrigerator has power but the display is dead, try resetting the electronic control board using these steps:

1. Unplug the refrigerator power cord. If the cord is difficult to reach, shut off the house circuit breaker for the fridge to completely disconnect electrical power.
2. Leave power off for 2 minutes.
3. Reconnect electrical power to reset the control board(s) in the fridge.

The control board or boards will reboot and reset. The display may begin working again.

Check Control Board Wiring

If the display is still dead after resetting the control board(s), check the wiring connections on the main electronic control board of the fridge.

Here’s a video that shows how to access the electronic control board on a common type of refrigerator:

If the wiring connections are okay, you may need to replace the electronic control board or the user interface control board.

Have a service technician test the control boards to determine which part needs replacing.
