9 Troubleshooting
1. Make sure that the power is connected to the fan.
2. Disconnect the power and verify that the impeller is not blocked.
3. Check the thermal contact (only for AC). If it is triggered the cause of overheating must be
investigated and taken care of. To restore the manual thermo-protector the power must be
disconnected for a couple of minutes. In case of automatic thermo-protector the resetting
will be done automatically when the motor has cooled down.
4. Make sure that the capacitor is connected according to the wiring diagram (only for AC).
5. If the fan still does not work, the first thing to do is to replace the capacitor (only for AC).
6. If the previous steps doesn’t solve the problem, contact your fan supplier.
7. If the fan is returned to the supplier, it must be cleaned, the motor cable must be
undamaged and a detailed fault description must be enclosed.
