Why does the refrigerator keep making noise? These may be the reasons

Refrigerator is one of the indispensable household appliances in our daily life. A good electric box can save me a lot of daily expenses and improve our daily living standards. However, various problems will occur during the use of refrigerators, and some friends may find that the refrigerator at home is constantly buzzing. But I never knew what the reason was? Today, let’s talk in this article about how to deal with such problems.

冰箱为什么一直有噪音

We all know that refrigerators rely on compressors and refrigerants to achieve refrigeration when they work in refrigeration. The compressor will make a little buzzing sound when it is working. But this is intermittent. Work will stop after a short period of time. Don’t work long hours continuously. If there is a situation where the refrigerator is buzzing all the time, then 100% is an abnormality.

There are two main reasons as follows

1. Caused by non-fault causes

1. Items in the refrigerator are improperly placed.

First check whether the items placed in the refrigerator are properly placed. Sometimes the items that are not placed and the slight vibration during working of the refrigerator will cause a common earthquake. Just find and place them.

2. Whether foreign matter enters the top of the refrigerator or inside the rear cover of the refrigerator.

3. The refrigerator needs to be placed smoothly at four corners. If there is unevenness, abnormal noise will occur.

4. The service life of the refrigerator is too long, and the freezing situation in the freezer is serious. In this case, the cooling effect of the refrigerator will be affected to a certain extent, which will greatly lengthen the working time of the compressor. Therefore, there will be a situation where the refrigerator keeps buzzing and does not turn off the machine.

2. Abnormal sound caused by the fault cause

1. The temperature control device of the refrigerator fails

If the temperature control fails, there are three situations.

One type of fault is that the temperature is wrongly judged as high temperature, so that the refrigerator fresh-keeping room and freezer room are always in working state and never stopped. The compressor will also be working all the time, which is the root cause of the refrigerator’s constant buzzing problem. Over time, the fresh-keeping room will freeze and become a freezer.

Another fault is the exact opposite of the previous one, that is, the temperature controller mistakenly judged it as low temperature, and the refrigerator stopped working. The compressor completely stopped and stopped working. The entire refrigerator was silent, and as time passed, the freezer began to melt. This kind of problem requires replacing parts. It is best to ask professional personnel to repair it.

Another possibility is caused by the improper setting of the temperature control knob. Just adjust it in time, usually adjust it to the middle position.

2. Refrigeration pipes are damaged or lack of refrigerant

After the refrigerator has been used for a period of time, the refrigerant in the refrigeration pipeline may leak. At this time, the refrigerant in the pipeline is insufficient, and there is not enough refrigerant to circulate in the pipeline after the compressor is working. It cannot function as refrigeration, and the temperature control command will keep the compressor working. This is the root cause of the problem.

Tip: If the refrigerator at home is faulty, it is best to find a professional person to repair it to avoid unnecessary losses. I hope the above content will be helpful to you. Thank you for reading.
