Troubleshooting

Fan does not turn on

Check that the power supply is switched on and the circuit breaker has not tripped. Verify all electrical connections are secure and correctly wired. Ensure the fan is not obstructed.

Reduced airflow or poor performance

Check the ducting for any kinks, blockages, or obstructions (e.g., debris, nests). Ensure all duct connections are sealed properly. Clean the fan's impeller and interior as per the care instructions. Verify the duct run is not excessively long or complex for the fan's capacity.

Unusual noise during operation

Ensure the fan is securely mounted and not vibrating against any surfaces. Check if any foreign objects have entered the fan housing. If the noise persists, it may indicate an internal issue, and further inspection or professional assistance may be required.

Fan cycles on and off intermittently

This could indicate an issue with the power supply or a thermal overload protection mechanism. Check the power source and ensure ventilation around the fan is adequate. If the problem persists, consult a qualified electrician or the manufacturer.
