Wine cooler not cooling at all; interior is at room temperature and compressor is not running.

Safety first: Unplug the unit before removing panels. Use caution around sharp metal edges.

Steps to diagnose:

• Check power: Confirm the outlet has power and the plug is fully inserted. Test with another device.
• Verify control settings: Ensure the unit is switched on and not in standby mode. Adjust the set temperature to a colder setting.
• Listen for compressor: With the unit plugged in, listen at the back for compressor hum or clicking. Repeated clicking without running suggests a start relay issue.
• Inspect start components: Remove the rear panel and compressor terminal cover. Check the start relay and overload for burn marks or rattling. Replace with a compatible BODEGA compressor start relay/overload kit if defective.
• Check control board: If the compressor never receives power, the main control board may be faulty and require replacement.

When to call a professional: If a new relay does not restore operation, the compressor or control board may need professional diagnosis.
