Close the door and check that no drawer, the IceTower tray or a package is holding it open. ### Can I change when the Liebherr freezer door alarm goes off? Yes. The Touch & Swipe freezers let you set how long the door may stay open before the alarm sounds. ### Why does my Liebherr show a warmer temperature right after the door alarm? Warm air came in while the door was open, and the freezer is now cooling harder to catch up. The displayed figure can run higher than the actual food temperature for a while. ### My Liebherr door alarm sounds with the door closed. What should I check? Look for a seal that has slipped out of its groove or a drawer that stops the door from closing fully. If both look fine, have the door and its sensing checked. --- **[Read on the site: Liebherr Door alarm: the freezer door has been open too long](https://freezerrepair.center/error-codes/liebherr-door-alarm/)** **[Book a visit with FreezerRepair.center](https://freezerrepair.center/schedule/)**
