Why does my air styler make a whistling or high-pitched sound?

A whistling or high-pitched sound usually points to restricted airflow, an attachment that is not seated correctly, or a partially blocked opening. It is worth checking this promptly, because a changing noise can be an early sign that airflow is not moving through the appliance normally.

Checks to carry out

1. Switch off, unplug and let the appliance cool.
2. Inspect the air inlet, outlet and fitted attachment for dust, hair or anything that may narrow the airflow path.
3. Refit the attachment so it sits exactly as described in the instructions.
4. Restart the appliance briefly and listen for any change in the sound.

If the noise fades after cleaning or refitting, the cause was likely airflow restriction. If the sound gets louder, the casing vibrates, or the appliance starts to smell hot, stop using it.

When to stop using it

Stop using the air styler immediately if the sound is accompanied by sparking, burning odour, loose parts or visible damage.

Next steps

If cleaning and refitting do not remove the noise, contact the retailer or store where it was purchased. They can explain the available next steps.
