Close both drawers fully and check that nothing is catching on the slides or gasket. If it comes back, it needs a visit. ### The blue light over ALARM keeps flashing on my Thermador drawers, but they are shut. Why? One drawer may not be closing all the way, often because of a package at the back or a slide out of line. If both are fully closed, the drawer sensing needs a technician. ### Can I switch off the Thermador drawer alarm for a party? Yes. Holding ALARM for three seconds turns the drawer-open alarm off, and holding it again turns it back on. Remember to re-enable it afterwards. ### Does the Thermador drawer alarm tell me if the freezer drawer is too warm? No, it only watches for an open drawer. Check the freezer drawer temperature on the display if food seems soft. --- **[Read on the site: Thermador undercounter freezer drawer beeping with a blue light: a drawer is open](https://freezerrepair.center/error-codes/thermador-drawer-alarm-light/)** **[Book a visit with FreezerRepair.center](https://freezerrepair.center/schedule/)**
