Touch the alarm icon to see the highest temperature reached during the outage. It shows for about a minute. ### Is my Liebherr broken if the power failure LED is lit? No, it is the FrostControl display recording that the freezer got too warm during an outage. It describes something that already happened, not a current failure. Touch the alarm icon to see the highest temperature reached. ### How do I decide what food to keep after the Liebherr power failure LED comes on? The peak temperature shown for about a minute after touching the alarm icon is your guide. Liebherr asks you to check whether food got too warm or even thawed. Touch the icon again to switch the display off afterward. --- **[Read on the site: Liebherr refrigerator showing Power failure LED](https://refrigeratorrepair.center/error-codes/liebherr-power-failure-led/)** **[Book a visit with RefrigeratorRepair.center](https://refrigeratorrepair.center/schedule/)**
