Broken hair dryer - Tips on repair

briefly about the design

Before you want to repair the hair dryer in the home, it is necessary at least in general terms, familiarize yourself with the device.Thus, the modern model of the art can consist of the following elements:

• power cord to connect to a power outlet;
• switch or speed selector;
• fan;
• heating element (spiral);
• engine.

As you can see, the design of the device is not complicated, so if you want to repair the hair, renovated difficulties should not arise.Next we will look at all of the major damage that may occur, and for each malfunction tell you how to fix it.Of the tools you need multimeter, screwdriver (or star) and, possibly, a soldering iron.

Troubleshooting

Due to its simple operating principle, often experience the following breakdown of household hair dryer:

• absolutely no power (device not included);
• not spinning fan blades or poor acceleration;
• at the smell of smoke either in the engine area something sparks;
• hair dryer is not blowing hot air (cold only).

No power - check the chain

First, if the hair dryer will not turn on, check the power source and the integrity of the electrical cord.To do this, you can use a screwdriver or a special indicator Tester - Multimeter.To learn how to use a multimeter and how to use the indicator, we are told in the relevant articles.

If there is a power outlet and hair dryer did not work, repair, review carefully the appearance of cord: perhaps somewhere he interrupted, frayed or incised.The most problem areas are considered to place the cord put into the enclosure, as well as the connection to the electric plug.If seemingly no obvious reasons for failure could not be found, proceed with the disassembly of the housing.Disassemble the dryer housing with your hands is not difficult, the main thing - to find all the attachment and remove them (they can be hidden behind the label, rubber plugs, etc.).

When you get to the interior design (pictured above), first check the place of the power cord connection to the other circuit elements.Very often the engine will not start because of the fact that there is no wire bonding at the site.If in your case it is all so simple repairs can be completed by soldering or twisting strands.

cord is serviceable, but the hair still does not work?We make repairs on and check the remaining circuit elements.If you have a diagram of your device model with a tester rang the other elements: fuse switch and mode switch.Not rare cases when the household appliance overheats and turns off due to the fact that the fuse blows.It should be replaced by exactly the same characteristics.

By the way, there is a reverse situation - dryer does not switch off after the hair drying.This is also the fault of the switch!

Another failure - does not work on / power off button.We have already told how to repair a light switch.Repair in this case is similar - check the tester break contacts, strip them to metallic colors and if you fix the damage with their own hands does not work, replace the switch.Similarly check and switch modes if hair does not switch speed or does not regulate the temperature (for example, does not work for 2 speeds), try to repair the controller or perform a simple replacement.

Fan does not rotate - clean it

Another type of failure - a problem with the fan, which does not accelerate.If the hair dryer did not work, because it is not spinning the fan housing and disassemble check how clean the blades.Sometimes the fan is not gaining momentum because it is wound hair.To repair You only need to be cleaned - to remove the blade from the shaft, remove all debris and re-install the fan in the seat. For more information see the repair process you instructions on the video below.In some models of equipment installed filters that also need to be cleaned.

By the way, if the fan is turned on the smell of burning, it is likely that hair stinks because of heavy pollution.Very often, a thorough cleaning helps to solve the problem yourself at home with a minimal set of tools for electrician!

air is not heated - looking spiral

Another no less popular fault - burnout spiral, which is the main heating element.If your fan is not heated or slightly warm air get to the spiral, it rang tester and make a visual inspection.Damaged heating element can try to repair, but more often after the repair (for example, Nichrome connection thread) runs for several months and a hair dryer is broken again.Spiral should be replaced with a new one to continue to breakdown from happening.

Problems with motor

Well, the last, the most unpleasant failure - when the hair dryer is not working due to the fact that the motor burned.In this case, you just can repair with a tester to make sure that the engine is defective.In addition, signs of breakage can be considered smell of burning and arcing in the fan area.To repair the device you are unlikely to succeed, so it is best to either replace the engine or take the unit to a service center.

That's all that I wanted to tell you what to do if the hair dryer is not working and how to perform the repairs with their own hands, if broken fan, switch or motor.We hope that the instruction provided was useful and interesting for you.By the way, the industrial model (construction) can be repaired on the same instructions in pictures.In fact, the building dryer in design is similar, only more protected externally and has a more powerful components inside!
