1. Check whether the communication pipeline is blocked. First of all, check whether the exhaust pipe is blocked by oil or other substances, which may be one of the reasons why the range hood is not smooth. If the smoke exhaust pipe is not blocked fundamentally, simple cleaning methods can be adopted, such as pouring drinking salt water and soda water. , in order to thoroughly remove the dirt in the pipeline.
2. Check whether the fan wheel is normal. If the fan wheel is damaged or not working normally, it is not only difficult for the range hood to exhaust oil smoke, but also may lead to increased noise. When checking, it is necessary to disassemble the shell of the range hood and observe whether the fan wheel is loose, deformed or worn. If problems are found, it is necessary to replace the fan wheel in time.
3. Check the oil absorber of the range hood. If the oil absorber is used for a long time and is not cleaned in time, it may cause blockage and affect the smoking effect of the range hood. When cleaning, you can remove the oil absorber first, clean up the dirty things inside, and then put them back.
4. Handle the control circuit fault of the range hood. If the circuit fails, it will be repaired according to the specific situation. Usually, it is necessary to replace damaged parts or circuits, and at the same time, ensure that all wire plugs and other connections are stable.
The maintenance of range hood is very important, which can avoid the failure caused by improper operation or untimely maintenance. Especially during the epidemic period, the range hoods in scenic spots, hotels and other public places must be maintained and cleaned frequently to ensure the normal operation of the work and the health and safety of personnel during the epidemic period.
