The weather is still very hot. Most people are not very comfortable when they go to sleep at night. If the noise of the refrigerator is too big, it will be even more difficult to enter the dream. Many friends have experienced such things and found that the noise of the refrigerator is getting bigger and bigger. What is the cause? Xiaobian will answer the question for you. There are three reasons for causing noise in the refrigerator: The refrigerator is not placed properly. The ground level of the refrigerator is not flat or the installation is not stable, which is the common cause of noise generated by the refrigerator. The solution is to turn the adjusting screw on the bottom of the refrigerator to adjust the height. When the adjusting screw touches the ground, the four feet are in contact with the ground. There are items on the top of the refrigerator. The refrigerator and the items placed on top of it will resonate when the motor starts, causing noise. Moving the items on the top of the refrigerator will prevent it from resonating, and the noise will naturally be eliminated. Something fell into the machine part at the back of the refrigerator. The rear part of the refrigerator (lower in the back of the refrigerator) has fallen into small things, such as caps, lighters, gadgets, etc., which also produces noise. Solution: After cutting off the power of the refrigerator, the small items dropped into the machine will be taken out and the noise will disappear. Experts explained that the fundamental role of the refrigerator is to extend the preservation time of food. A good refrigerator should be silent and fresh. Therefore, while we require low noise, we must pay more attention to the preservation effect. Can't mute for silence. In addition, manufacturers now have reduced the noise of the refrigerator to less than 42 decibels, and the noise gap of each brand has been reduced by 1-2 decibels, which is equivalent to the sound of a needle falling to the ground. According to the relevant regulations issued by the state, the noise value of the refrigerator should not exceed 52 decibels.
