The buzzing sound generated by the refrigerator during operation may be caused by various reasons. Here are some possible reasons and their solutions: 1. Normal phenomena
When the refrigerator is in operation, it produces a certain amount of noise due to the operation of components such as the compressor and fan. If the buzzing sound is short-lived and the sound level is below the national standard of 45 decibels, then this is usually a normal phenomenon and will not affect people's normal lives. 2、 Abnormal causes and solutions
1. Reason for uneven placement of the refrigerator: If the refrigerator is not placed smoothly, the sound may increase due to vibration. Solution: Use a spirit level to check if the refrigerator is level, and adjust the refrigerator floor mats to achieve a level state, thereby reducing vibration and noise.
2. Reason for blockage of cooler or fan: Dust accumulation may cause difficulty in fan operation, resulting in buzzing sound. Solution: Regularly clean the heat sink and fan with a soft cloth to keep them clean.
3. Reason for compressor problem: The compressor of the refrigerator is one of the most likely components to produce noise. If the compressor ages or is damaged, it may cause abnormal sound. Solution: Please have professional maintenance personnel inspect and replace it.
4. Reason for refrigerant flow: When refrigerant flows in the refrigerator system, it produces a certain sound, which is a normal phenomenon. But if the sound is too loud or accompanied by other abnormal sounds, professional examination may be necessary. Solution: Please have professional maintenance personnel check if the refrigeration system has any leaks.
5. Reason for ice formation inside the refrigerator: If there is too much ice formation inside the refrigerator, it will cause a buzzing sound during operation. Solution: Regularly defrost and keep the inside of the refrigerator dry.
6. Reason for poor sealing of refrigerator door: If the refrigerator door is not sealed tightly, it will cause a buzzing sound when the refrigerator is running. Solution: Check if the sealing strip of the refrigerator door is aging or damaged, and replace it if necessary.
7. Reason for other electrical devices around the refrigerator: If there are other electrical devices around the refrigerator, such as microwave ovens, televisions, etc., it may interfere with the normal operation of the refrigerator and cause buzzing sounds. Solution: Move other electrical devices away or adjust their positions to avoid interference with the refrigerator.
8. Reason for temperature controller malfunction: The temperature controller has malfunctioned and cannot sense the internal and external temperatures. The refrigerator's engine will remain in operation, continuously cooling, resulting in an uninterrupted buzzing sound. Solution: Replace the thermostat.
9. Reason for pipeline resonance: It may be due to the handling personnel accidentally loosening the pipeline during the transportation of the refrigerator. Solution: Find professional maintenance personnel to fix the pipeline.
10. Reason for placing items at the top: Placing items at the top of the refrigerator can easily cause resonance and produce a buzzing sound when the compressor is working. Solution: Try not to place items on top of the refrigerator. 3、 Summary and Suggestions
If the buzzing sound of the refrigerator suddenly becomes abnormally loud or there is unusual noise, it is recommended to investigate and handle it according to the possible reasons mentioned above. If unable to resolve the issue on your own, it is recommended to contact a professional repair service. Regular maintenance and cleaning can help reduce these issues and extend the lifespan of the refrigerator. At the same time, when using the refrigerator, attention should be paid to keeping it dry and clean, avoiding placing too many items to avoid affecting the normal operation of the refrigerator.
