The loud noise of the range hood may be an installation problem. Did you contact the regular after-sales installation at that time? I suggest you contact after-sales to have a look.
Is the range hood noisy? It's the first time I bought a range hood, and I heard from my colleagues that the effect of super-class range hood is correct. The new house is being renovated and the contractor is ready to install it. The trial machine can also be used, just wait for the natural air to open, and the noise is very small.
How to solve the problem of loud noise of range hood In view of the characteristics of wide noise frequency of kitchen exhaust fan and easy blockage of sound absorption orifice plate by oil smoke, Nanchang Jialu thinks that it can be maintained as a whole and treated in stages. When the exhaust muffler is installed at the oil drain, attention should be paid to the noise reduction design from the aspects of appearance, moisture resistance and rust prevention, and a bracket should be set at the bottom of the muffler. In order to prolong the service life of the muffler, an air duct oil injection elbow should be installed in the muffler before installing the muffler. In order not to affect the air quality of the air processor, the exhaust fan mouth and the air inlet of the air processor should be set in opposite directions to prevent the exhausted oil fume from being pumped back to the kitchen.
What should I do if the range hood is noisy? Cause analysis and treatment of high-speed grinding noise: improper assembly makes the blade loose and produces abnormal noise when touching the air guide frame, so reassemble and tighten the blade; The motor bearing is badly worn, so the bearing of the same model must be replaced; If the motor is poorly assembled, correct the gap between the stator and rotor of the motor to make it uniform. If there is axial movement, an appropriate washer should be added; The deformation of the fan blade is unbalanced, correct the fan blade and adjust the dynamic and static balance of the fan blade; The design of gas outlet pipeline is unreasonable. Turn the air outlet pipe as little as possible, turn it big and round. Fault 3: Cause analysis and treatment of excessive vibration of range hood: unstable fixation or poor installation, with rubber pad or foam plastic, the fixation is not firm; There are foreign bodies on the blades, and the dirt inside is too thick. Remove foreign bodies and internal dirt on the blades; The spindle and cutter sleeve are eccentric, and the concentricity of the spindle and cutter sleeve is readjusted; If the motor bearing is worn or the bearing hole is too large, replace it with a new bearing of the same specification; If the motor winding is short-circuited or open-circuited, replace the winding or motor.
The range hood is noisy, the smoke is not good 1, the flue exhaust is not smooth, and the fan load is heavy;
2. The range hood is not firmly fixed and the vibration is too great;
3. Poor dynamic balance of the fan (this problem is easy to occur when the blades are deformed and installed incorrectly after washing);
4. The motor bearing is short of oil or slightly damaged.

Are range hoods in Germany and Italy noisy? The sound is directly proportional to the speed of the range hood. For the range hood with small turbine, the turbine diameter of FT is only 24 cm, so the big gear of FT is only equivalent to the middle gear of Germany and Italy. The big gear of Germany and Italy is 52 decibels, which is also the representative of small noise in the industry.
The range hood is noisy and cooking is annoying. What should I do? Better buy a new one. My new Aucma range hood is clean, quiet and quiet.
