The farm uses a variety of electrical devices, which greatly facilitate the life of the layman. But during operation, they can fail and break. Repairing a hair dryer with your own hands is easy to do, since most problems can be easily fixed at home. But first you need to understand the device and the principle of operation of the device.

Design features
Before proceeding with the elimination of the breakdown, it is necessary to understand how the household appliance works. The main components of the hair dryer are as follows:
- motor;
- fan;
- heating elements;
- electrical circuit.
A hair dryer, depending on the number of modes, can have several switches and different external characteristics. The body can be made of various materials and fastened with special screws. The heads generally have a non-standard pattern, it can be a plus sign, a pitchfork or an asterisk. Before disassembling the device, it is worth taking care of the necessary tool.
In addition, the sash can be secured with special latches. Therefore, you must be extremely careful not to break off the fragile plastic parts.
The motor of the device can be operated with direct current of 12, 24 and 36 V. To rectify the mains voltage, a diode bridge is used. Simpler devices use a single diode.
Inspection procedure
If the hair dryer is completely devoid of signs of life or does not function well, then a visual inspection of the power circuit is required. It is best to conduct events in the following order:
-
There is a problem with the cable. It is necessary to start the procedure for inspecting the power cable from the outlet. The problem may lie in the absence of an electrical network or some other malfunction. If the voltage exists, then you need to inspect the cord of the electrical appliance, moreover, most often the breakdown occurs in the place where it enters the case. Then they move to the fork. Before carrying out repair work, it is necessary to de-energize the device. If there are any kinks, there are no burners, then it is necessary to disassemble the hair dryer and check the connection points of the wire with the internal parts. It often happens that the engine falls off. The situation can be corrected by ordinary sealing. - Fan malfunctions. In this case, the device simply stops spinning or does it very slowly. To identify the cause, you will also need to disassemble the unit, otherwise you will not be able to get to the part. At the very beginning, the impellers are inspected; they should not be dirty and dusty. Often the mechanism does not gain momentum precisely because of the hair that wound around it during operation. Next, you need to disassemble the structure completely, thoroughly clean it and the filters on it. If the manipulations did not produce the desired effect, and the device did not work, then the breakdown cannot be eliminated on its own, you will have to take the hairdryer to the service.
- Breakdown in the engine. The most unpleasant problems happen with the engine. You can understand that the reason lies in it by the characteristic smell of burnt wiring, as well as by sparks that slip in the place where the motor is located. It won't be easy to fix the problem if you don't have experience. First, using a tester, it is necessary to identify the exact location of the malfunction, and only then, based on the problem, fix the breakdown or completely replace the element with a new one.
- Heating element problems. In the event of such a malfunction, cold air flows from the household appliance instead of a hot stream. Most often this happens due to a burnt out or broken spiral. To repair the breakdown, it is necessary to disassemble the device, the fan, in this way it will be possible to get to the desired part and replace it. It is possible to make repairs, but, as a rule, after some time it will become unusable again.
Here is a list of the most common problems that affect the performance of your hair dryer. More serious problems happen, but only experienced craftsmen can fix them.
Some Tips
Repairing a professional device is quite difficult. Since the parts contained in it are equipped with special controls and various options, such as the Care button. In addition, the spiral is often made from a special alloy, which, when heated, creates negative ions that have a beneficial effect on the quality of the hair.
But even such devices have the same technique:
- cable;
- switches and various buttons;
- cleaning from dust and dirt;
- inspection of the spiral and motor;
- capacitor and resistor control.
But before carrying out independent repair work, you must familiarize yourself with the schematic diagram of the device. As you can see, fixing household hair dryers is not that difficult. But if there are any doubts, then you should not do the repair yourself, but better take them to a service center.
Since any incorrectly performed action can lead to the fact that the device will become unusable completely, and even specialists will not be able to repair it.
