Touch the alarm icon to silence the tone. If it comes back, it needs a visit. ### Why does my Liebherr alarm LED flash after I loaded groceries? Warm food going in, or warm air entering while food was rearranged, can lift the freezer temperature past the alarm point. Touch the alarm icon to silence the tone and keep the door shut. The flashing should stop on its own once the freezer cools again. ### When is a flashing alarm LED on a Liebherr a sign of an appliance problem? When there is no recent warm load or long door opening to explain it and the flashing continues. Liebherr lists an appliance problem as the third possible cause. That is when to call customer service. --- **[Read on the site: Liebherr refrigerator showing Alarm LED flashing](https://refrigeratorrepair.center/error-codes/liebherr-alarm-led-flashing/)** **[Book a visit with RefrigeratorRepair.center](https://refrigeratorrepair.center/schedule/)**
