The wine cooler displays 'AL' or an alarm icon with beeping; the internal temperature is significantly above the setpoint.

Safety: No immediate electrical work is required; basic checks can be done with power on. Unplug before removing panels.

Steps to address AL:

• Confirm door closure: Ensure the door is fully closed and the gasket is sealing properly.
• Allow recovery time: If the door was recently open for an extended period or many warm bottles were added, allow 12–24 hours for the temperature to recover.
• Check for airflow: Listen for the evaporator fan running when the compressor is on. If silent, investigate the fan motor and wiring.
• Inspect condenser: Clean the condenser coil and verify the condenser fan is operating to ensure efficient cooling.
• Monitor temperature: Use an independent thermometer to verify the actual cabinet temperature. If the unit cannot reach the setpoint after cleaning and checks, a sealed system or sensor fault may be present and require professional service.
