1. Range Hood Fails to Eliminate All Cooking Odors
The scenario where the range hood is faulty and unable to eliminate cooking odors is not uncommon.
Possible causes include insufficient cleaning, leading to dust and grease accumulation, causing leaks and reducing device performance.

Most effective troubleshooting steps to take:
- Clean the range hood immediately after use to prevent grease and dirt adhesion. If your range hood uses activated charcoal, replace it every 6 months. Regular maintenance is essential for optimal performance.
2. Noise-Inducing Exhaust Fan
The exhaust fan creates loud noise or strange sounds when running, common issues encountered. Various reasons contribute to this problem, such as:
- - The fan blades may be broken or obstructed by foreign objects, causing them to collide and generate noise.
- Incorrect installation of the ventilation pipes results in loose or misaligned joints. This can also be a cause of abnormal noise during operation.
- - Check the positioning of the pipe installation and adjust the joints accordingly.
3. Quạt máy hút mùi phát tiếng kêu lạ
The fan in the range hood is designed to create powerful suction due to its high machine capacity, making it easy to extract odors. However, this design also makes it prone to pulling in sharp objects, causing them to collide with the fan blades and creating unusual noises during operation.

To remedy this situation, you need to locate and remove any sharp objects to ensure the fan operates normally.
4. Airflow Occurrence During Operation
Some users experience the phenomenon of airflow when the machine is running. The cause of this issue includes:
- - If you set the machine to odor elimination mode, you will feel the airflow during operation.
- Setting the rapid suction and elimination mode will make the machine operate at high power, creating a strong airflow.
- 5. Prolonging Fan Operation
Switch the internal switch in the machine to extend the airflow duration.
If after checking, the machine is not in extraction mode but still produces airflow, contact the warranty center or bring it to the store for inspection and repair.
- 6. Dim Light Issue
