Question: The range hood is very noisy.

Answer:

① When the machine is turned off, after the motor stops rotating, the two blades of the check valve will automatically fall down. At this time, a "clicking sound" is a normal phenomenon. ② If it is just a loud sound or the sound of the exhaust air, this kind of sound is normal. Generally, the greater the resistance of the flue and the longer the length of the flue pipe, and the higher the speed of the fan, the greater the noise will be. If there is an abnormal sound or a very loud sound when the range hood is turned on, this kind of sound is abnormal.
