Is it normal for the refrigerator to keep buzzing?

1, which may be caused by thick ice accumulated inside the machine. In hot weather, the thermostat is broken. 3. It may be that the compressor power is too small to move or it is broken. 4. There is no place. Suggested solution: 1. In the high temperature environment, there is a lot of frost on the wall of the refrigerator, which will make the refrigerator make a fault sound. The temperature of the thermostat must be adjusted, not too low. It's best to unplug the power supply and let some frost melt by itself. The storage position of food in the refrigerator should also be rearranged, and there should be corresponding gaps between foods to reduce the number of times the refrigerator door is opened. If the thermostat and control circuit board fail, causing buzzing, they need to be replaced directly. 2. If the surrounding environment of the refrigerator exceeds 34 degrees, the external temperature it feels is too high, and its heat will also increase. Frequently opening the door when using the refrigerator at this time will cause uneven heat dissipation and make a sound. At this time, it is necessary to check the power and refrigerant of the compressor, readjust it if the power is too small, and refill it if there is no refrigerant. 3. Check whether the position of the refrigerator is stable, uneven or there are abnormal items behind the box. Change the location and choose a wide and barrier-free place to let the refrigerator dissipate heat.
