Is your range hood switch resting?

In the case of range hoods, if you repair them in some places, you need to call them** to make sure, and under normal circumstances, it should be about the same.

I think that in general, if you should look at it from this, it should have been repaired, and you can try it.

Find a professional to come to the door, generally if the range hood is a brand (boss, Fotile, Siemens), the whole machine is guaranteed for five years, and important parts are guaranteed for three years. Door-to-door maintenance is more suitable!

1. If the automatic control fails, the indicator light will not light up. Most of these faults are due to lack of cleaning and maintenance, so that the gas sensor on the board surface is stained with oil, resulting in the sensor being hindered, in fact, at this time, you only need to remove the sensor, put the mesh cover into the detergent and clean it with a brush, if the gas head is dirty, you can wash it with anhydrous alcohol and put it back in place, troubleshooting.

2. When the motor can rotate, the noise is loud and the shell is very hot. This kind of obstacle is mostly caused by serious lack of oil or wear in the electric rotation, when repairing, first of all, remove the fan blade, pinch the rotor shaft end with water and shake it gently, if it is not loose, the feel is tight, it means that there is a serious lack of oil, if there is a loose phenomenon, the feel gap is large, it means that the wear is serious, and the new bearing should be replaced at this time.

3. If the smoke absorption effect is poor. If the installation point is too high from the stove, lower the installation point appropriately; If the seal fails to leak, replace the seal to make it tightly sealed; The activated carbon in the internal circulation fails, and the activated carbon is replaced; If the exhaust pipe is too long or the direction of the air outlet is not selected properly, the exhaust pipe should be shortened appropriately and the direction of the air outlet should be re-selected; If the voltage is too low, a voltage regulator should be configured if necessary; The suction channel is blocked by oil stains, and the oil stains are cleaned; If the pressure difference between indoor and outdoor is too large, open doors and windows appropriately to reduce the pressure difference between indoor and outdoor.

Now the range hood is a light touch switch, the situation of self-switch should generally be your range hood control circuit board or switch control board, due to poor sealing, by oil and water erosion caused by the range hood malfunction, you can disassemble, clean and dry in the case of disconnecting the power supply. The probability of a tact switch turning on and off is very small.

There is a problem with the control panel, and the switch control circuit is faulty.

Definitely, we should follow the principle of "opening early and closing late" when using the range hood every day. That is to say, turn on the range hood three minutes before cooking, and don't turn off the range hood immediately after cooking.

We all know that when the stove is lit, the gas is burning, and carbon monoxide is produced at this time.

and other gases, which are harmful to the human body. If the range hood is turned on early, it can remove these harmful gases before they are generated; The reason for closing late is the same as opening early, which is to get rid of the fumes by inhaling for a while.

But with the spine often I understand the truth, many people are in the process of use can not do, daily life is sometimes busy cooking, will forget to turn on the hood in advance, often wait until the beginning of the stir-fry has the smoke before realizing to open the hood, as for the cooking after even washing the dishes are not silver to sell Sakura want to wash, not to mention to go to the kitchen to turn off the hood. At this time, you can consider buying some intelligent range hoods, such as using mobile phone apps

Remote control or automatic delay shutdown function, now there are still a lot of this kind of range hood on the market, my home German range hood, their range hood is basically equipped with smoke stove linkage and delayed shutdown function design. As the name suggests, the smoke stove linkage is that when the stove is ignited, the range hood will be automatically turned on immediately, which can eliminate carbon monoxide and ensure that the cooking can suck away the oil smoke as soon as the dish is put into the pot; And after the stove is turned off, the smoke will automatically delay for three minutes and then shut down by default, which will continue to operate to remove the remaining oil smoke in the kitchen within three minutes, and ensure that the oil smoke can be smoothly discharged from the home, and there is no problem of oil smoke backfilling.

Normally, when the gas burns for 20 minutes, the nitrogen oxides that are harmful to the human body are more than 9 times higher than the standard, and the carbon monoxide is more than 10 times more than the standard. However, if the smoke exhaust equipment is used after the gas is ignited, the wheel celery is only 1 times more than the standard. If the smoke exhaust time is extended, the harmful starvation substances produced by combustion can be quickly eliminated.

Therefore, the range hood should be turned on at the same time as the gas is lit or in advance. After turning off the gas, turn off the range hood after a few moments.

The general reasons are divided into the following types: 1. It may be a power supply problem, the power supply is out of power or the power socket of the range hood.

Poor contact causes the hood to turn off by itself. 2. It is possible that the engine of the range hood is broken. When the hood is set to the state of automatic shutdown.

Or there is a bad problem with the internal motherboard or wiring of the range hood. Suggested solution: 1. If it is a power supply problem, there is no electricity on the power supply.

Plug it in or wait for a call. If it's a fuse.

If there is a short circuit or a broken beam that needs to be replaced, you can find a professional person to deal with it. 2. If there is a problem with the engine of the range hood, the power cord or interface is loose, and the power supply must be replaced or connected to the brand. The range hood switch is poorly connected or damaged.

It is necessary to overhaul and replace the electrical connection wires or terminals in the electronic switch.

Loosening, falling off. The point of detachment can be found and the cause of reconnection can be found. The indicator light of the range hood is not on.

Connect the power cord. The battery is damaged or the light pool should be replaced. The electronic transformer that controls the light is broken.

Replace the electronic transformer. The circuit control board is faulty. Access switches.

The power cord connecting to the motor is disconnected. Connect the power cord. The capacitor is damaged, and we replace the capacitor.

The motor burns out or wears out. Replace the motor. If the circuit control board fails, the circuit board should be overhauled and replaced.

The motor overheat protection rubber is disconnected, and the motor is disassembled to connect the overheat protection or will automatically reset after a while. The switch indicator of the range hood is not on. Light-emitting diodes.

bad, the diode must be replaced. If the switch board is damaged or other faulty, the switch board can be replaced. After the range hood interface is installed, the installation interface should be resealed.

The range hood does not turn off

1. It may be that water has entered the touch screen of the range hood, which causes the switch button of the touch screen to fail and cannot be turned off. 2. It is also possible that the circuit of the button circuit board in the range hood is broken, resulting in the phenomenon that the switch fails and cannot be turned off. 3. It is also possible that the medium of the touchpad is faulty.

4. The chip of the range hood is faulty.

Suggested Solution:

1. If the internal buttons of the touch screen fail due to water ingress on the touch screen, you only need to wait for the internal moisture to dry and turn on normally.

2. When it is determined that there is no water inside, some people find that the touch screen of the range hood still does not work and cannot be turned off, so it is necessary to replace a new circuit board, turn on the range hood, and see that the switch button can start the switch normally. If it still doesn't work, then you need to move on.

3. When the first two steps are checked, the switch of the range hood is still not working, so it is necessary to check the medium of the touch board of the range hood for a long time, and if it is found that the medium has a problem, you can replace it with a new touch board medium.

4. If the medium of the touch screen is also intact, then it is necessary to consider whether the chip is faulty, this is the time to check the chip, and then eliminate the fault of the chip, and turn on the switch that can restore the normal function of the range hood.

The switch of the range hood is used as follows:

1.Turn on the power switch and plug in the power cord.

2.Open the panel of the range hood and press the switch button to start the range hood.

3.Adjust the wind speed of the range hood, and choose the gear of different good friends according to your needs.

4.After using the Li Chong, press the off button, and Youhuai turns off the range hood.

Notes:1Before using the range hood, turn on the cooking equipment such as a gas stove or induction cooker before starting the range hood.

2.When using the range hood, keep the kitchen doors and windows closed to avoid outside air entering and affecting the ventilation effect.

3.Regularly clean the oil mesh and oil cup of the range hood to ensure its normal operation and service life.

4.When using a range hood, pay attention to safety to avoid electric shock or other accidents.

Causes

Now the range hood is a light touch switch, the situation of self-switch should generally be the range hood control circuit board or switch control board, due to poor sealing, by oil and water erosion caused by the range hood malfunction, can be disconnected, cleaned, dried in the case of disconnection of the power supply. The probability of a tact switch turning on and off is very small.

Precautions

There are three types of range hoods on the market: thin, deep, and cabinet. When purchasing, you should first determine the type you want to buy according to the specific layout of your kitchen and personal preferences.

The thin range hood is heavy and lightweight, small in size, and easy to hang, but its thin design and low motor power make a considerable part of the cooking fume cannot be included in the suction range and has the opportunity to escape indoors, and its smoke exhaust rate is significantly lower than that of the other two types of models. Therefore, most consumers do not consider this type when buying range hoods.

If your kitchen wall is thin (non-load-bearing wall), can not bear the weight of the deep range hood, due to the limitations of the kitchen layout, and can not place the cabinet range hood, then, the thin range hood is also your ideal choice.

The deep range hood has a smooth and beautiful appearance, high smoke exhaust rate, and can match with different styles of modern kitchen furniture, which has become the first choice for consumers when buying range hoods, and occupies a dominant position in the market. Various manufacturers have launched different models of deep range hoods.
