There are several reasons why the refrigerator suddenly becomes louder:
1. Shaking noise.
2. Pipeline noise.
3. Conduction noise.
4. Fan noise.
The emergence of the refrigerator provides great convenience for us to store vegetables, melons and fruits, as an electrical appliance, it is inevitable that a certain sound will be emitted during operation, but if the sound is very loud, it is not right. So what's going on when the refrigerator suddenly gets louder? Let's talk about the problem that the refrigerator suddenly becomes loud.
1. The noise of refrigerator shaking may be that the four corners of the bottom of the refrigerator are not close to the ground when it is installed, resulting in normal vibration during the operation of the refrigerator causing the refrigerator to shake. Check the corners of the bottom of the refrigerator, and the uneven places can be flattened.
2, refrigerator pipeline noise, refrigerator due to long-term use, pipeline aging loose, coupled with the original normal vibration of the refrigerator, the pipeline shaking touches the refrigerator wall will produce noise. You need to disassemble the machine for inspection and replacement or buy a new machine.
3, the refrigerator conducts noise, the bottom of the refrigerator compressor works to make a sound, through the refrigerator shell conduction amplification. Do not place debris on the bottom of the refrigerator.
4, refrigerator fan noise, refrigerator in a long time after use, the fan surface will be attached to a lot of dust, as the dust accumulates more and more, the refrigerator noise will become larger and larger. The fan surface needs to be removed to clean.
