The kitchen ventilation fan started to turn around and buzzed for a while

Ying Mu Nian should be a problem with the motor, and it is estimated that there is a lack of oil;

You can remove the exhaust fan, clean the plastic blade impeller, and then look at the motor of the exhaust fan, whether there is an oil filling hole, if there is, you add the appropriate amount of Qingfan's oil for lubrication, the problem should be solved, if there is anything else unclear, you can consult us, Jing Electromechanical Technology, we will provide you with the reputation of hail resistant green island wind exhaust fan and, Zhengye exhaust fan troubleshooting.

Hefei Green Island Electromechanical Equipment will answer for you:

Ventilation fan ventilation fan products are noisy? The conditions that produce noise may be the following:

1. When the ventilation fan is running, the motor covers the abnormal sound emitted by the exhaust sound. (Inspection method: remove the ventilation fan and run it with power on to observe whether there is any abnormal sound, or take off the wind wheel of the ventilation fan and electrify it to observe whether there is any abnormal sound when the motor is idling).

2. The sound of ventilation fan exhaust is loud.

3. The friction sound caused by other obstacles when the ventilation fan is running.

4. When installing the ventilation fan, it is not fixed and produces vibration friction sound.

5. The exhaust pipe is bent or blocked.

6. Noise caused by the vibration of the ventilation fan and the ceiling.

Solution to ventilation fan noise:

1. Replace the motor with a new one or read the product description before use;

2. The larger the exhaust air volume, the greater the exhaust sound; The sound of exhaust is related to the environment used by the customer, if the user installs in the narrow area of the toilet or ventilation space with a limited area of air flow, it will cause the noise of the ventilation fan to be louder than the sound in the empty space, that is because the environment used is different, 3. Clean up the obstacles of the ventilation fan and reinstall it.

See if it's a loose set screw or a deformed page turn causing the shaking.
