Shut the column and run a hand along the gasket to feel for gaps. If it comes back, it needs a visit. ### How do I stop my True column from beeping? Close the door. To silence the buzzer while the door stays open, press ALARM; the display shows whether the alarm is on or off. ### I turned the door alarm off. Is that a problem? Only if the door is later left open without anyone noticing. Turn it back on when you are done loading. ### Why does the alarm go off with the door closed? The door may not be fully sealing, or its switch is not seeing it. A door that closes without a firm seal also lets humid air in. --- **[Read on the site: True DOOR ALARM: the wine column door is ajar](https://winecoolerrepair.center/error-codes/true-door-alarm/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
