Possible Causes

How to Fix / Troubleshooting
Safety first: Turn off power before cleaning or adjusting the fan.
- Clean coil and grille: Remove debris from the coil and protective grille. Wash with low‑pressure water.
- Check surroundings: Ensure there is sufficient clearance around the unit (per Hewalex guidelines) and that no structures block airflow.
- Inspect fan blade: Confirm the blade is correctly oriented and firmly attached to the motor shaft.
- Test motor speed: After restoring power, observe whether the fan reaches normal speed. If it remains slow, the motor or its capacitor may need replacement.
