1. The exhaust duct of the range hood is not clean: due to long-term use, the exhaust duct of the range hood is easy to accumulate oil stains, resulting in poor exhaust. The exhaust pipe can be cleaned regularly to ensure unobstructed.
2. The exhaust port of the lampblack machine is blocked: If the exhaust port of the lampblack machine is blocked by lampblack, the lampblack cannot be discharged smoothly. Removing smoke from the exhaust port can solve this problem.
3. The motor of the range hood is damaged: the motor is the key to the exhaust of the range hood. If the motor fails or burns out, it will lead to poor exhaust and the damaged motor needs to be replaced.
4. The rotation of the fan blades of the range hood is inflexible: if the fan blades are heavily loaded or inflexible due to aging and lack of maintenance, the smoke exhaust effect will be affected. At this time, it is necessary to clean or replace the fan blades.
5. Improper use of range hood: If the range hood is used improperly, for example, the exhaust function of the range hood is not turned on during cooking or the range hood is not tightly connected with the flue, the lampblack will not be discharged well. In this case, you must read the instructions carefully before using the range hood and make sure to use it correctly to avoid this problem.
To sum up, if the range hood cannot exhaust smoke correctly, it is mainly because of incomplete cleaning, damaged mechanical parts or improper use. To effectively solve this problem, it is necessary to maintain the range hood according to the corresponding methods.
