What to do if the range hood is abnormal, and what is the problem if the range hood has an abnormal

We are about to wash the bar is professional to do smoke machine cleaning, and the following three conditions should be checked for abnormal noise:

1. Whether the vibration and abnormal sound caused by the uneven installation of the smoke machine;

2. Whether the dynamic balance is unbalanced and abnormal caused by damage to the impeller inside the smoke machine;

3. Whether the smoke pipe of the smoke machine is not installed properly and causes air leakage and abnormal noise;

Did you disassemble and wash it yourself? If you disassemble and wash it yourself, you put the impeller of the range hood and the motor when you install it, and the level is not adjusted, and the motor noise is loud and the operation is not stable

The oil exhaust fan is stained with grease and dirt, and it makes an abnormal noise when it turns.

Remove and clean, clean! Wash with Mr. Vermeer.

Causes and solutions for abnormal noise in range hoods:

1. It may be that there is a lack of oil in the bearings inside the range hood, which causes the range hood to squeak. At this time, it is necessary to purchase special lubricating oil, add it to the bearing position of the range hood, and then install the range hood to use it normally.

2. If the gas sensitive probe of the range hood is polluted by oil smoke, it will squeak as soon as it is turned on. Wipe the gas sensor with a clean, damp cloth dipped in an appropriate amount of dish soap, and then rinse it with clean water. Finally, after it is naturally dried, there is no problem with using the edges.

3. If the range hood is not installed firmly, and its position is offset in the process of use, it will also cause the hood to squeak. You need to find the loose screws of the range hood and tighten it, or contact a professional installer to reinstall the range hood.

Daily cleaning work of range hood.

1. When cleaning the shell of the range hood, you can use a soft cloth strip dipped in neutral cleaning liquid to wipe it on the shell of the range hood, which can effectively remove dust. However, it should be noted that try not to use highly corrosive washing liquids to avoid corrosion.

2. Before the range hood is used, the plastic wrap can be pasted on the inside of the oil box, so that in daily use, the oil stains will not be contaminated to the inner wall of the oil box.

3. When cleaning the oil mesh, you can first remove the oil mesh with a screwdriver, soak it in the prepared warm water with detergent, wait for about 10 minutes, and then scrub it with a brush.

Reasons why the range hood has abnormal noise:

It is possible that the installation position of the range hood is not firm, which causes the range hood to resonate with the wall during use, resulting in abnormal noise. The range hood needs to be re-fixed and the height of the range hood should be determined according to the height of the user.

The smoke exhaust pipe used is relatively long, or the installed smoke exhaust pipe has too many curves, resulting in excessive pressure loss during use, which will cause the suction power of the range hood to decrease, and the smoke exhaust will be poor and produce abnormal noise. It is necessary to shorten the smoke exhaust pipe in time and increase the radius of the flue turn, which can effectively reduce the noise generated by the smoke exhaust.

If the range hood has been used for a long time and has not been cleaned, there will be more oil smoke sticking to the motor, hood and other areas, which will cause the weight of the fan of the range hood to be unbalanced, resulting in abnormal noise. Regular cleaning is required.

Range hoods use methods that do not make squeaks and squeaks.

When using the range hood daily, it is strictly forbidden to bake the stove under the range hood, which can easily lead to damage to the range hood and accidents. Moreover, the range hood is a high-power electrical appliance, so the socket connected to it needs to be dedicated and a large-sized wire.

It is very important to clean the range hood according to the steps in the manual to avoid damage to the range hood. All disassembled spare parts need to be stored to prevent deformation. If you don't know the range hood, you need to contact a professional for cleaning.

Causes and solutions for abnormal noise in range hoods:

1. The installation problem of the range hood.

If the installer does not install it in place at the beginning, the installation position of the range hood will become unstable after a period of long-term use, which will cause the range hood to resonate with the wall, resulting in abnormal noise.

If it is caused by this problem, then the hood needs to be re-fixed.

2. The smoke exhaust pipe of the range hood is unreasonable.

If the smoke exhaust pipe is very long, or the installed smoke exhaust pipe has many curves, resulting in excessive pressure loss when the range hood is in use, the suction power of the range hood will become smaller, and the smoke exhaust will not be smooth, which will lead to abnormal noise.

If it is caused by this problem, it is necessary to shorten the length of the smoke exhaust pipe and increase the turning radius of the smoke exhaust pipe, which can reduce the noise caused by the abnormal noise.

3. Abnormal noise caused by not cleaning the range hood for a long time.

If the range hood has been used for three or four years and has never been cleaned, then there will be a lot of oil smoke dirt inside the motor or range hood, which will cause the weight of the fan of the range hood to be unbalanced, resulting in abnormal noise, so it needs to be cleaned.

The suggestion is to find a master to deeply clean the range hood to solve the oil problem, while ordinary detergents can only clean the oil on the surface, but cannot completely solve the noise problem.

1. The range hood has always had a sound, which is very regrettable because the bearing in the range hood has no oil, so this situation occurs. 2. The long-term use of the range hood will cause a large amount of dirt and oil stains to accumulate on the range hood, and it will also cause the gas sensor probe to be affected by the oil smoke, because of this reason, the range hood will make a sound. 3. The sound of the range hood and the installation will also be related, the range hood will move after a period of use, it may also be because the installation is not installed, of course, it may also be because the screws fixing the range hood are loose, and the range hood will sound.

Suggested solutions: 1. If it is because there is no oil in the bearing of the range hood, then you need to open the range hood, take out the bearing inside, and then add lubricating oil to the top of the shaft Huai imitation bearing, and then install the bearing back to the original place after it is done. 2. If the gas sensor probe is full of dirt due to the long-term use of the range hood, you need to clean the gas sensor with a rag and dish soap.

3. If the fixing screws of the range hood are loose, you need to reinstall them to avoid ringing.

1. The installation position of the smoke machine is not firm. If the installation position of the hood is not firmly installed, it will produce abnormal noise, which is the cause of the resonance between the range hood and the wall. At this time, we need to re-fix the range hood, and install it reasonably according to the height of the family.

2. The smoke exhaust pipe is too long and dead bend. The more the smoke exhaust pipe of the range hood is bent, the greater the positive pressure loss will be, and the suction power will become smaller, which is easy to cause poor smoke exhaust. Therefore, the smoke exhaust pipe should be shortened as much as possible, and the turning radius should be as large as possible, so as to ensure smooth exhaust, increase the smoke exhaust effect, and reduce noise.

3. The smoke machine needs to be cleaned in time. If the range hood is not cleaned for a long time, the internal surface of the motor, turbine and hood will stick too much oil, and the fan backup leakage will be unbalanced, which will cause the sound of the hood to vibrate.

4. Improper installation of check valve. In the case of a range hood with a check valve, it must be checked to confirm that it is fully open.

5. The air is not circulated. When using the smoke machine, it is necessary to keep the flow of kitchen air wide, which can prevent the air in the kitchen from forming negative pressure and ensure the suction capacity of the smoke machine.

There are generally several situations in which the range hood has abnormal noise, and the treatment methods for different reasons are not the same, so it is necessary to find the cause to solve it.

1. The installation position of the hood is not firm: one of the very important reasons why the range hood will make abnormal noises is that the installation position of the range hood is not strong, which leads to the resonance between the range hood and the wall. In the face of this situation, the first thing we have to do is to re-fix the range hood and install it reasonably according to the height of the family, usually without meeting.

2. The smoke exhaust pipe is too long and dead bending: Of course, if there are many curves of the smoke exhaust pipe when the smoke hood is installed, it will cause a large pressure loss, which will lead to the reduction of the suction power of the range hood and the poor smoke exhaust. For this reason, we should shorten the smoke exhaust pipe as much as possible, and the turning radius should be as large as possible, so as to ensure smooth exhaust, so as to increase the smoke exhaust effect and reduce noise.

3. The hood needs to be cleaned in time: I believe we all know that if the range hood has not been cleaned for a long time, there must be too much oil sticking in the motor, turbine and hood, which will cause the weight of the fan to be uneven and cause abnormal noise.

Reason: The installation position of the smoke machine is not firm. The resonance between the range hood and the wall will produce abnormal noise, so the range hood needs to be re-fixed; The smoke exhaust pipe is too long and dead bends.

The smoke exhaust pipe should be shortened as much as possible, and the turning radius should be as large as possible; The range hood needs to be cleaned in time. If the range hood is not cleaned for a long time, the weight of the fan will be unbalanced, resulting in a large vibration of the hood; The check valve is not installed properly and must be checked to confirm that it is fully opened. Expansion:

Matters that should be paid attention to in range hoods. 1. The power cord socket must use a reliable special socket and the plug must not be changed without authorization, in case of leakage grounding, a current circuit can be provided to avoid electric shock. 2. The power supply voltage and frequency used should be consistent with the requirements of the product.

The three-core power socket must be reliably grounded, and the distance between the power socket and the body should be greater than or equal to 1000 mm, and the grounding wire must not be overlapped on the water pipe and gas pipe. 3. The left and right sides of the installed range hood body should be kept horizontal, and the air outlet should be slightly lower when the air duct is installed to prevent oil backflow. And the distance to the body should be short, and the turns should be few (it is better to make only one turn).

4. During use, if there is abnormal noise, rotor does not rotate, smell, smoke, etc., the power supply should be cut off immediately for inspection and repair. If the electrical appliance is faulty, it must not be disassembled and assembled without authorization, and must be repaired by the maintenance department, if the power cord is damaged, it must be replaced with a special flexible cord or a special component purchased by its manufacturer or maintenance department.
