What s the matter if the hair dryer is not hot when it is windy, and how to repair the hair dryer if

Causes and solutions:

1. Internal failure of the heating rod.

Solution: Replace the heating rod.

2. The degree sensor is broken.

Solution: Replace the sensor.

3. The internal fan is broken.

Solution: Repair and replace the internal fan.

The biggest possibility is that the heating wire of the hair dryer has been short-circuited due to a fault, so it cannot produce hot air.

If the heating wire is short-circuited, you can pat the hair dryer shell and dredge the wire end of the string;

If the heating wire is broken, it is more troublesome, and the heating wire can be reconnected, but even if the heating wire is connected, the service life will not be too long (note that the heating wire must not be soldered with solder wire). It is also possible to open the casing and overlap part of the heating wire inside or cut part of it to reduce the resistance, and the temperature can be increased according to p=i r.

Disassemble and see if the cable connecting to the heating network is broken, replace it with a new one!

The hair dryer has two resistance wires, one of which is connected in series with the motor to limit the current. One is thick is the effect of heating and blowing hot air, and your situation should be a thick open circuit, and the thin one is small because the current is small, so the heat is small, and only the breeze comes out. It's worthless to repair Generally windy and not hot, it's a problem Either the line is broken It is recommended that you do not repair it privately, it has avoided danger, or change it.

Hair dryers generally have two gears: cold air and hot air. If there is no hot air, it may not be changed to the hot air gear, and it will take a few seconds to change to the hot air gear before it will heat up. If there is no hot air yet, it may be that the heating wire has burned out.

Summary. Hello dear . The maintenance method of the hair dryer only heats up and does not turn:

1. First look at the air inlet to see if there is any hair entering the motor blade. If there is, it will be basically good to deal with it.

2. Only heat does not turn, indicating that there is no problem with the switch. The electric hair dryer on the market generally supplies power to the heating wire and the motor in series after bridge rectification through 4 diodes. The heating wire heats up, so as to judge that the carbon brush contact of the motor is also good, otherwise the heating wire will not be able to heat.

At this time, you can no longer turn on the power and watch the heating wire heat up, because the temperature is too high and it is easy to burn the heating wire. Unplug the power plug first, then open the shell, and turn the fan of the motor a few times by hand to see if its rotation is flexible. If it gets stuck, add some lube.

3. If it doesn't work, you have to check whether the motor has a power supply, if there is a power supply, but the motor does not rotate, it means that the motor is broken. Just change the motor.

How to repair a hair dryer that only heats up and doesn't turn?

Hello, I'm a co-teacher who asks questions, just call me Xiaofang. I am very happy to serve you before the wait, please be patient and wait for 3-5 minutes to talk about training, and Xiao Fang will answer for you! !

Hello teacher. Hello dear . The maintenance method of the hair dryer only heats up and does not turn:

Unplug the power plug first, then open the shell, and turn the fan of the motor a few times by hand to see if its rotation is flexible. If you want to stare at the god is stuck, add some lubricating oil to the loss. 3. If it doesn't work, you have to check whether the motor has a power supply, if there is a power supply, but the motor does not rotate, that is, the motor is broken.

Just change the motor.

The hair dryer is overheating and suddenly stops blowing, and it may be broken. It may be caused by the solder joint falling off, it may be caused by excessive temperature, or it may be caused by a problem with the part.

1. It may be that the solder joint falls off and cannot be energized, if you have the ability to disassemble and connect it yourself, the general hair dryer may not be energized because the solder joint is off, or the internal circuit is loose, or the short circuit, check the version first, if it really doesn't work, take it to the repair shop for maintenance.

2. It may be due to the high temperature, the hair dryer has turned on the temperature control protection function. If the hair dryer suddenly doesn't work during use, it may be because the temperature is too high, and the temperature control device automatically cuts off the power supply, and when the temperature drops, it can be used.

3. It may also be because the life of the hair dryer is too long, resulting in problems with the parts. When the hair dryer is running for a long time, the temperature of the body will rise, and if it exceeds a certain value, it will cause the electronic components inside the hair dryer to burn out, and it will not work, and it needs to be reinstalled.

How to choose a hair dryer

1. For thick and curly hair, you can choose an ionic or tourmaline-type hair dryer. Ionic or tourmaline hair dryers release negative ions that help break down water droplets on your hair, making it dry faster. As a result, your hair is less likely to curl after you blow dry it.

If your hair is thick and frizzy, buy a hair dryer with ionic or tourmaline inside.

2. If you have very thin or dry hair, you can consider using a ceramic or porcelain hair dryer. Ceramic hair dryers also use negative ions to prevent hair from frizzing, which allows hair to dry faster.

3. If you have a lot of hair, you can choose a titanium hair dryer. Titanium hair dryers provide heat at a stable, uniform temperature, so it's not a good option for fine or damaged hair. However, if you have very thick or heavy hair, a titanium hair dryer can drastically reduce your drying time.

1. It may be caused by an abnormality in the circuit connected to the hair dryer, when the voltage is unstable or a short circuit, it will lead to the phenomenon that the hair dryer suddenly does not blow, so you should wait for the voltage to stabilize before continuing to use, or ask a special electrician to help repair it.

2. It may also be caused by the failure of the motor inside the hair dryer, once the motor fails, it will not be able to drive the fan blades to rotate, so that the hair dryer can not blow, then the motor should be replaced with a new one, or the hair dryer should be directly replaced with a new one.

3. It may also be caused by the use of the hair dryer for too long, if the hair dryer is used for a long time, the temperature of the fuselage will become very high, when the temperature exceeds the set temperature, the electric heating element inside the hair dryer will burn out, and it will automatically shut down, no longer continue to blow, then the hair dryer can only be replaced with a new one.

4. It is also possible that the temperature of the body becomes very high because the hair dryer has been used for too long, and the temperature control device of the hair dryer automatically cuts off the power supply in order to prevent the hair dryer from being burned out, so that the hair dryer can not continue to blow.

Hair dryerHot airIf it is gone, it may be that the heating wire is broken, the switch is in poor contact, the power cord is broken, and the blades cannot operate normally, which is described as follows

1. If the heating wire is broken, the heating wire is burned out, you can look at the manual or the Internet to see which model you buy with what heating wire, and buy a one with the same specifications to install it.

2. The switch has poor contact, and the bad switch is the switch that controls the hot and cold air, as long as the switch is disassembled and replaced.

3. If the power cord of the heating wire is broken, if it is the welding place of the power cord or the power cord is broken, it is necessary to use a new power cord for welding, and at this time you need to use electric welding tools.

4. If the blade cannot operate normally, see if the blade is deformed or displaced due to collision, and if so, fix the motor position back to the original position. If it's because of debris stuck on the blades, clean up the debris.

Notes:

1. The hair dryer nozzle should be more than 5 cm away from the hair to avoid the water on the hair hitting the hair dryer and causing a short circuit.

2. Do not use the hair dryer for a long time, otherwise the motor will heat up.

It is easy to burn out, so try to control the time of each use within 3 hours.

The hair dryer has cold air and no hot air, and the treatment method is as follows:

1. If the heating wire is broken, in this case, the heating wire is burned out, and you can only buy a wheel punch of the same model and install it.

2. If it is caused by poor contact of the switch, in this case, it is a bad switch to control the hot and cold air switch, as long as the switch is disassembled and replaced.

3. If the power cord of the heating wire is broken, in this case, a new power cord should be connected.

How to buy:

1. When buying a hair dryer, try to use it to see if there is any noise and whether the size is within the standard range. If the noise is relatively loud, this will affect its comfort in use. On the other hand, the less noise will be generated, the better the quality.

2. The hair care function of the hair dryer can not be less, when using the hair dryer, you can use the hair care function, which can prevent the hair from being damaged, which will also affect the normal home life. Lap cheating.

3. The power of the hair dryer should also be paid attention to, it is best to choose a small power, as long as you can dry your hair, if you choose a hair dryer with high power, this radiation will be greater, and you should pay special attention to it.

The hair dryer does not blow the air, only the reason for the heat machine and how to repair it is as follows:

1.If the fan in the back is broken, you can disassemble it to see if the motor and the blade are loosely fixed, causing the motor blade to not rotate, if so, just dip it with glue.

2.If the motor does not rotate, it may be that the motor is broken, and you will have to replace it with a new one, but a small motor like a hair dryer seems to be only available in the electronics market, so if it is not convenient to buy, you can buy a new hair dryer directly.

3.A hair dryer is a combination of a set of heating wires and a small fan with high speed. When the electricity is turned on, the heating wire will generate heat, and the air blown by the fan will pass through the heating wire and become hot air.

If only the small fan is rotating, and the heating wire is not hot, then only the wind is blowing out but not hot.

4.The heating principle of the hair dryer is: the thermal effect of the electric current. The current is passed through the heating element with a relatively high resistance and generates heat. Then the fan blows the wind out.

5.Although there are many types of hair dryers, the structure is similar, all of which are composed of shells, handles, motors, fan blades, electric heating elements, wind shields, switches, power cords, etc.

It may be caused by a broken power cord of the heating wire or a broken power cord of the motor.

1. The hair dryer will rotate without hot air. The possible part of the fault is that the heating wire power cord is broken. Detect whether the heating wire power cord is broken, if it is broken, replace the heating wire power cord;

2. The motor does not rotate, and the heating wire is red. The possible part of the fault is a broken motor. Check it to see if the motor has a power supply, if there is a power supply, the motor does not rotate, the motor is broken, just replace the motor; Extended Resources:

The air blown out of the hair dryer is a dry wind, if it is used for too long, it is easy to cause water loss, causing heat damage, the secret to minimize the damage is: use a towel to pat the moisture on the hair first, gently comb the hair with your hands, and then use the hair dryer.

1. It may be caused by an abnormality in the circuit connected to the hair dryer, when the voltage is unstable or a short circuit, it will lead to the phenomenon that the hair dryer suddenly does not blow, so you should wait for the voltage to stabilize before continuing to use, or ask a special electrician to help repair it.

2. It may also be caused by the failure of the motor inside the hair dryer, once the motor fails, it will not be able to drive the fan blades to rotate, so that the hair dryer can not blow, then the motor should be replaced with a new one, or the hair dryer should be directly replaced with a new one.

3. It may also be caused by the use of the hair dryer for too long, if the hair dryer is used for a long time, the temperature of the fuselage will become very high, when the temperature exceeds the set temperature, the electric heating element inside the hair dryer will burn out, and it will automatically shut down, no longer continue to blow, then the hair dryer can only be replaced with a new one.

4. It is also possible that the temperature of the body becomes very high because the hair dryer has been used for too long, and the temperature control device of the hair dryer automatically cuts off the power supply in order to prevent the hair dryer from being burned out, so that the hair dryer can not continue to blow.

Changing the carbon brush is done, and the person who sends so many messages has never lived with a hair dryer at first glance.
