Hair dryer that goes to safety what to do?

When your hair dryer goes into safe mode while you have been quietly using it, this indicates a overheated and/or that it is no longer sufficiently ventilated. Indeed, all hair dryers are equipped with a thermal safety which engages and cuts the voltage of the device when the thermostat detects too high a temperature in the device and therefore a failure of the ventilation system. This safety system prevents heat-sensitive components, in particular the motor, from melting.

But then, Why is your hair dryer overheating and going into safety mode? Many causes may be at the origin:

  • overuse. This can happen when you use the device for too long at a very high temperature.
  • obstruction at the level of the air flow of the hair dryer which does not allow it to be sufficiently ventilated.
  • un dirty filter which no longer fulfills its barrier role.
  • a hardware failure. It may be that an essential internal component in the ventilation system has failed: thermal fuse, fan, electronic card or resistor.
Caution: If you notice that the power cord or the shell of the hair dryer is damaged or melted, unplug it from the power source immediately and do not use it anymore because there is a risk of   and, in the worst cases, a risk of fire or electric shock.

What to do when your hair dryer goes to sleep on its own?

When your hair dryer goes to safety, you will have to try to diagnose the origin of the problem for so réparer effectively the dysfunction. To do this, please follow the troubleshooting steps below in order.

Check that the device is in good working condition

At first, your hair dryer has gone into standby due to overheating due to a bad environment of use. If your device is very hot, or smells of burning, overheating is confirmed. In this case, here are the few points to check to try to understand where the overheating can come from:

1 – Did you come fromuse intensively and at high temperature your hair dryer that went into safety? If so, the problem is solved. Indeed, although the device is programmed to heat at high temperature, it is not immune to overheating if the use drags on or that certain components allowing the ventilation tire. In this case, wait about ten minutes and try again to use it. For the next long uses of your hair dryer, we advise you to activate the cold air button from time to time to prevent the components from overheating and the device's circuit breaker from being activated.

2 – Make sure the hair dryer vents are clean. If this is not the case, clean them with a dry, lint-free cloth. Also pay attention that the air circuit can be done correctly. You don't have to never block the ventilation or the evacuation of the air.

3 – Use your hair dryer in an environment where the temperature is between 5 ° C and 40 ° C.

After overheating and your hair dryer has gone to safety, always wait 10 minutes before trying to turn it back on. If the following points are respected but the hair dryer continues to go into standby during your use, it's a safe bet that its filter is clogged.

Clean the hair dryer filter that goes into safety

The role of the air filter is to trap the dust and dirt present in the air, without reducing the air flow necessary for the hair dryer. Over time, dirt can accumulate on the filter and it will then no longer be able to fulfill its role effectively. As a result, in addition to reducing the incoming air flow, the particles can also find their way into the engine block et lead to overheating and therefore the safety of the hair dryer. If you smell a burnt dust smell, it's a very good bet that the fault comes from the filter.

A hair dryer's air filter is usually located at the back or on the handle. To solve the problem, you will then need clean the filter too clogged. Depending on the model of your vacuum cleaner, the filter may be in different places and the cleaning instructions may differ. Refer to the user manual for the procedure corresponding to your model and brand of hair dryer. If you no longer have it on paper, you will most certainly be able to find it dematerialized on the manufacturer's website, under the “Instructions for use” section.

Note: On some hair dryer models, it is not not possible to access the filter (often on older models of hair dryers or low-end models). If the procedure is not indicated in the instructions for use, then it is certainly not possible to clean the filter of your hair dryer.

Unfortunately, if the previous checks and manipulations have given nothing, your hair dryer probably shuts down because an internal component has failed. Given that the hair dryer goes into standby when there is overheating or when it detects that the ventilation system is no longer efficient enough, the failure will most certainly come either from the thermostat, thermal fuse, resistance, ventilateur, or the electronic card.

At this stage, the manipulations require electrical clearances solid because you will have to open the hair dryer, test its various components and replace them knowing that similar spare parts are practically impossible to find, especially if your device is old. There is also a risk of electric shock and irreversible damage to the device. This is why we advise you to call on a professional.

If your faulty hair dryer is still under guarantee (2 years minimum in France or more if you have taken out an extended warranty), call the after-sales service of the retailer or the manufacturer. The repair costs will be borne by them. On the other hand, if your device is no longer entitled to the guarantee, you can choose to contact the manufacturer's after-sales service to see if they have a personalized solution to your breakdown (in the event of a proven manufacturing defect); or contact an independent professional repairer. Don't forget to ask for an estimate to see if the repair price is worth the cost or if it is better to buy a new hair dryer.
