Many families have encountered this situation in the process of using refrigerators, that is, the refrigeration effect of refrigerators is not good, and the refrigeration is particularly slow. For example, the family has just made dumplings and wants to put them in the refrigerator for quick freezing, but after half a day, they are only half hard when opened. In this case, you may think that there is something wrong with your refrigerator. In fact, this is not necessarily because the refrigerator has a fault, but also because the temperature setting gear is wrong, or the things are not placed in the correct position. Generally, an ordinary refrigerator is divided into two parts: the upper part and the lower part. The functions of the upper part and the lower part are different. The upper part is refrigerated and the lower part is frozen. So if you need to freeze things, such as fresh meat, dumplings, etc., you need to put them in the drawer below. Of course, if the cooling of the drawers below is also slow, it is necessary to check the causes. We can check the following aspects.
1、 Check whether the refrigerant leaks. Refrigerant is a very important part of the refrigerator, which directly determines whether the refrigerator can refrigeration normally. Refrigerant leakage will reduce the pressure and greatly reduce the refrigeration effect.
2、 The thermostat gear is set incorrectly. The refrigerator should set the corresponding gear according to the actual temperature change during the year. For example, if the external temperature is low in winter, the refrigerator's temperature controller can be set lower to reduce the compressor's working load and reduce power consumption. In summer, the opposite is true. The temperature in spring and autumn is moderate. If the temperature controller is not adjusted properly according to the seasonal changes, it will be slow to achieve rapid cooling when the external temperature changes.
3、 If it is a large refrigerator, check whether the fan is blocked due to too much stuff, which causes the temperature to not circulate normally and the compressor runs for too long. Or if the fan motor is short circuited and aged, the cooling effect will be slow.
4、 Lack of Freon. The principle of refrigerators and air conditioners is similar. They both need to use Freon for refrigeration. If they are used for a long time, fluoride will gradually be lacking, and the refrigeration effect will be reduced. You can solve the problem by asking a special maintenance personnel to add some fluoride.
The above are most of the possible reasons for the slow cooling of refrigerators at home. Some can be solved by themselves, while others need to be solved by special maintenance personnel.
