Troubleshooting
If you encounter issues with your range hood, refer to the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not turn on | No power supply; damaged cord/plug | Check power connection, circuit breaker. Contact qualified electrician if cord/plug is damaged. |
| Low airflow/poor suction | Clogged filters; improper ducting; external factors | Clean or replace filters. Ensure ducting is correctly installed and free of obstructions. Verify external vent is not blocked. |
| Excessive noise | Improper installation; loose parts; ducting issues | Ensure all mounting hardware is secure. Check for loose components. Inspect ducting for kinks or restrictions. Note that some noise is normal, especially at higher fan speeds. |
