If it has been used for more than 12 to 18 months, makes strange noises or vibrates when turned on, and involves heavy cooking grease, it means the motor and wind wheel have excessive grease accumulation. Professional deep disassembly cleaning is needed to restore suction.
Causes of suction decline
Kitchen grease accumulates over time, passing through the filter and attaching to the inside of the wind wheel and motor. When the wind wheel blades are covered in thick grease, the rotation speed slows down and the dynamic balance is lost, directly causing a significant drop in extraction performance and even motor overheating.
When to seek professional handling
When you observe the following with your range hood, schedule professional disassembly: the machine has been used for over 1.5 years, operation is accompanied by heavy running noise or abnormal vibration, and suction cannot be restored after cleaning the filter alone.
DIY maintenance vs. professional scope definition
For home safety, DIY is limited to cleaning the external filters and machine surface. Never disassemble internal screws, touch motor circuits, or forcibly remove the wind wheel to avoid part damage or safety loopholes from improper installation. Deep disassembly must be performed by professional teams.
