6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not cooling | No power, insufficient ventilation, temperature setting too high. | Check power connection, ensure vents are clear, lower temperature setting. |
| Excessive noise | Unit not level, fan obstruction, compressor issue. | Place on a level surface, clear fan area, contact support if compressor noise persists. |
| Display error codes | Internal fault, sensor issue. | Refer to the full manual for specific error codes or contact customer support. |
