Wine cooler cools poorly; temperature is higher than setpoint and fluctuates.

Safety first: Unplug the cooler before cleaning or accessing fans.

• Condenser cleaning: Remove the rear lower panel and vacuum the condenser coil thoroughly. Use a brush to remove stubborn dust.
• Check condenser fan: Confirm the fan spins freely by hand and runs when the compressor is on. Replace the condenser fan motor if it is noisy, seized, or not running.
• Internal airflow: Inside the cabinet, ensure that bottles are not pressed directly against the rear wall or blocking vents between zones.
• Evaporator fan: Listen for the internal fan. If silent, inspect and replace the evaporator fan motor as needed.
• Monitor performance: After cleaning and ensuring proper airflow, allow 12–24 hours for temperatures to stabilize.
