If you encounter difficulties or are unsure about any step, consult a qualified electrician.

Perform cleaning at least once a year, or more frequently in dusty environments.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not turn on. | No power to the fan; faulty switch; loose wiring connection; motor failure. | Check circuit breaker/fuse. Ensure switch is functional. Verify all electrical connections are secure. If motor is new and still not working, contact support. |
| Fan is excessively noisy. | Loose mounting screw; debris in blower wheel; worn motor bearings (if old motor). | Ensure motor assembly is securely mounted. Clean blower wheel of any obstructions. If noise persists with a new motor, ensure it is correctly installed and not vibrating against the housing. |
