• Check door: Ensure the door is fully closed and the gasket is sealing.
• Allow recovery: If you recently added a large amount of warm food, allow several hours for temperature to stabilize.
• Test door switch: Open and close the door while listening for the alarm to stop and start appropriately. If erratic, inspect or replace the door switch.
• Mute alarm: Use the alarm reset button if available, but do not ignore repeated alarms without checking temperature.
