Why is the Sakura range hood noisy and suddenly loud

There are many reasons for this.

If it is a new range hood, contact the merchant to return it.

Some times for a long time, the fan has too much oil stain, and the range hood is aging.

There is too much oil in the hood, or it is a foreign matter that enters, mainly because the fan has too much oil and is unbalanced due to the unbalanced force, and it is also possible that the motor lacks lubricating oil, or the motor bearing is broken.

There could be a number of reasons:

Cause. 1. The installation of the range hood is not firm: if the installation of the hood is not stable, it will cause the smoke to resonate with the machine in the process of working and produce noise. The solution is to re-install the range hood.

Cause. 2. Improper installation of check valve: If there is a problem with the installation of the check valve, it will directly lead to the reduction of the smoke exhaust effect of the range hood and make noise. The solution is to reinstall the check valve.

Cause. 3. Deformation and improper installation of the wind wheel: due to the long-term use of the wind wheel, oil pollution will accumulate, and even deformation and aging, resulting in unbalanced operation. The solution is to replace the rotor or clean the rotor again, and if it is not installed properly, it can be reinstalled.

Cause. Fourth, the hood has not been cleaned for a long time: this will lead to excessive oil accumulation in the internal components of the motor, turbine and hood, which will make the fan rotate unsteadily and cause the hood to be noisy, so we should clean the range hood regularly.

Cause. 5. Poor air circulation in the kitchen: We must always keep the air circulation in the kitchen, which can not only prevent the air in the kitchen from forming negative pressure, but also ensure the smoke exhaust effect of the range hood.

If it is cause four, the following methods can be considered:

1. Pressure cooker steam flushing method. Boil the cold water in the pressure cooker, remove the pressure limiting valve when the steam is continuously discharged, open the range hood, align the steam water column with the rotating fan blades, because the high hot water steam continues to rush into the fan blades and other components, the oil and sewage will flow into the waste oil cup along the road until there is no oil in the oil cup.

2. Detergent and vinegar soaking method. Remove the impeller of the range hood, soak it in a basin of warm water mixed with 3-5 drops of dish soap and 50 ml of vinegar, soak for 10-20 minutes, and then scrub with a clean rag, and the shell and other parts are also cleaned with this solution. This method has no damage to people, no corrosion to the device, and the surface still retains the original luster after cleaning.

3. Soap liquid surface coating method. Make the soap into a paste, and then apply it to the surface of the impeller and other devices, after the range hood has been used for a period of time, remove the impeller and other devices, wipe it with a rag, and the oil stain will be off.

Causes and solutions:

1. If the range hood keeps making a sound, the range hood should be disassembled and carefully checked, which may be caused by the lack of oil in the bearing of the range hood, an appropriate amount of lubricating oil should be added to the bearing, and then the range hood should be installed in its original position.

2. It is also possible that the gas sensor probe of the range hood has not been cleaned for too long, and the gas sensitive probe of the range hood is polluted by the oil smoke and jujubes, which will cause the range hood to make a noise. Soak the rag, wipe it back and forth with an appropriate amount of dish soap, wipe it clean with water, and leave it for a period of time until it dries naturally before using.

3. The range hood has a lot to do with the installation, it may be that the oil bump Chang smoke dismantling machine has taken a long time, the position has been offset, and it may be installed improperly when it is installed. The sound of the oil hood may be due to the loosening of the screws fixing the range hood, and the range hood should be removed for reinstallation, and the screws fixing the range hood should be tightened and the impeller should be re-debugged and installed.

There are many reasons, 1. The installation of the range hood is not firm, if the installation of the hood is not stable, it will cause the smoke machine to resonate with the machine in the process of work, resulting in noise. 2. The flue is blocked and the check valve is not installed properly, which means that if there is a problem with the installation of the check valve, it will directly lead to the reduction of the smoke cracking effect of the range hood and make more noise. Workaround:

1. Re-install the range hood, and at the same time see whether the height of the range hood is just suitable for your own use, so as not to cause the phenomenon of meeting in the later use. 2. Clean the flue regularly and reinstall the check valve, so that the range hood will be discharged more smoothly in the smoke exhaust work, and there will be no great wind noise. 3. Replace the wind wheel or clean the wind wheel, and reinstall it if it is not installed properly.

4. Clean the range hood regularly. It is necessary to clean the range hood regularly, otherwise the oil stains are scattered in various parts of the range hood, which will lead to failure or other failures for a long time. 5. It is necessary to keep the air circulation in the kitchen frequently, which can not only prevent the air in the kitchen from forming negative pressure, but also ensure the smoke exhaust effect of the hail closed range hood to a certain extent.

There are several reasons why a range hood may be loud:

1.Fan speed is too high: The fan speed of the range hood is too high, which will increase the noise, you can try to adjust the fan speed.

2.Poor ducts: If the ducts are not smooth and hail, it will cause the fan to need more force to expel the smoke, which will increase the noise.

3.Poor installation: If the range hood is not installed firmly, it will lead to stuffy vibration and increased noise.

4.Poor fan quality: If the fan quality of the range hood is poor, it will also lead to increased noise.

Workaround:1Adjust the fan speed: The fan speed can be adjusted according to the use case to reduce noise.

2.Clean the air duct: Clean the air duct regularly to keep it clear and reduce noise.

3.Reinstallation: If the installation is not secure, it can be reinstalled to ensure that the range hood is secure.

4.Replace the fan: If the quality of the fan is poor, you can consider replacing the fan and choose the best product.

It could be due to the following reasons:

1.Dry and improper installation: The installation position, height, and fixing method of the range hood will affect the noise and noise of the hood. If not installed properly, it may cause excessive noise.

2.Fan problem: The fan brother oak of the range hood is the main component that produces noise, and if the fan is not of good quality or aging, it will produce noise.

3.Fume pipe problems: Problems such as bending and clogging of fume pipes can also lead to excessive noise.

4.Product quality problems: If the purchased range hood itself has quality problems, it may also cause excessive noise.

It is recommended that you contact after-sales service or professional maintenance personnel for inspection and repair.

<> solution to the loud sound of the range hood: 1. The installation position is not appropriate or the installation is not firm. If the range hood is not installed firmly, it will resonate with the machine when the range hood is working and make noise, then we can reinstall and fix the range hood.

2. The smoke exhaust pipe is too long or there is a "dead bend" phenomenon. The more the smoke exhaust pipe of the range hood is bent, the greater the pressure loss, resulting in smaller suction and poor smoke exhaust. 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 the smooth air outlet, mainly to increase the smoke exhaust effect and reduce the noise.

3. The range hood has not been cleaned for a long time, so that the inner surface of the motor, turbine and range hood sticks too much oil, resulting in the voice and vibration of the range hood may be too large, and the range hood should be cleaned regularly.

4. Caused by poor air circulation, it is necessary to keep the air circulation in the kitchen when using the range hood, so as to prevent the air in the kitchen from becoming negative pressure and ensure the suction capacity of the range hood.
