1. If the refrigerator doesn't cool, you should check whether the connecting line of your refrigerator is normal. This problem seems simple, but it is still easy to be ignored, especially when the power cord is exposed. This is why it is the easiest to prevent your refrigerator from freezing. Generally speaking, you just need to plug in the power.

Check whether your refrigerator door is closed. If you don't turn it off, your air conditioner will run out and the refrigerator won't freeze! This is actually something that we should pay more attention to at ordinary times.

3. If the power supply is connected and the refrigerator door is closed, and your refrigerator is still not cooling, then you should check the compressor of the refrigerator. If the compressor is normal, there will be some slight sounds, which can be heard by normal people, and there is also a slight vibration feeling.

4. If the refrigerator compressor works normally, you can unplug the power supply at this time, and then listen to the sound of water flowing in the copper tube of the refrigeration system. If you really hear such a sound, then there is something wrong with the refrigerant side of the refrigerator refrigeration system. Simply put, your compressor can no longer serve the refrigerator normally.

In addition, if there are too many things in the refrigerator, it may also cause the illusion that your refrigerator is not frozen. At this time, you can try to slim down your refrigerator, and maybe it will return to normal. Generally speaking, this situation is caused by not knowing how to use the refrigerator.

6. If the refrigerator works too long, there will be a thick box on the refrigerator wall. If this box is left untreated for a long time, it will also have a certain impact on the refrigeration of your refrigerator, so you need to take it out of the refrigerator often.
