6. Troubleshooting
This section addresses common issues you might encounter with your fan.
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not start | No power, incorrect wiring, damaged motor. | Check power supply, verify wiring connections (polarity), inspect for damage. |
| Reduced airflow | Blocked intake/exhaust, dirty blades, incorrect speed setting. | Clear obstructions, clean blades, check speed control settings. |
| Unusual noise or vibration | Loose mounting, foreign object in fan, worn bearings. | Tighten mounting screws, inspect for foreign objects (power off), contact support if bearings are suspected. |
| Overheating | Insufficient ventilation, operating outside temperature range. | Ensure adequate space for airflow, verify ambient temperature is within limits. |
