Liebherr Refrigerator Display Dark or Controls Not Responding

When the display on a Liebherr refrigerator goes dark, or the touch controls stop responding, the first worry is that the unit has stopped cooling. Sometimes it has, and sometimes it has not. A few quick checks can tell you which.

First, find out whether it is cooling

Open the door and listen. Feel for cold air and look at the interior light. If the compartment is still cold and the compressor or fan runs, the cooling system may be fine and the problem may lie in the display alone. If everything is warm and silent, power is the main question.

Simple checks

• Check that the plug is firmly in the outlet, and that the outlet works with another small device.
• Look at your breaker panel for a tripped breaker, especially after a storm.
• Make sure the controls are not locked. Many models have a lock function that stops the buttons from responding, and your manual explains how to release it.
• Wipe the control area with a dry or very slightly damp soft cloth. Moisture or grease on a touch panel can confuse it.
• Check whether a display saving mode is switched on, which can dim the screen after a short time.

What not to do

Please do not pull the unit out and open the electronics panel. A refrigerator holds mains power inside the cabinet. And avoid repeated unplugging, since every restart stresses the board and can hide a pattern we need to see.

When we come out

If the display stays dark, flickers, or the unit has no response after these checks, we test the power supply, the wiring, and the control board. We explain what we find and send a written price before any work. See our refrigerator repair page, then confirm your neighborhood in the service area list. Repairs carry a 30-day warranty.
