A hairdryer doesn't have many parts but it can go wrong if it gets clogged with dust and hair. Dryers have a small fan which is placed behind a heating element. When the dryer is turned on the electricity powers the fan, which blows hair past a heating element which warms the air coming out of the nozzle.
If the air flow is obstructed and the air becomes too hot, a thermostat cuts off the power to prevent burning out the motor.
When the temperature cools down the hairdryer will often start working again.
What is causing the problem:
There is a vent at the back of the dryer which sometimes gets blocked with hair or dust and stops the correct amount of airflow coming through it.
What to do:
Make sure this vent is clean. You can use a vacuum to clear the vent from the outside.
Or refer to our article on How to lubricate your hairdryer's motor - this will show you how to open your hairdryer and get rid of dust inside the dryer.
Warning: Opening your hairdryer may invalidate your warranty.
Hopefully this has helped you with that burning question and your hair is back in style.
Always refer to the manufacturers instructions.
