Why does the refrigerator not cool it? Mostly due to these reasons
A lot of things that need to be refrigerated suddenly become open and catch people off guard. It greatly affects daily life, and it also wastes time to find a maintenance technician to repair it. There are actually many reasons why the refrigerator does not cool. Some simple small problems can be solved by yourself. Let’s take a look at what to do if the refrigerator does not cool and what are the relevant information about the reasons why the refrigerator does not cool!
The first thing you need to know is how the refrigerator works. The refrigerator is a continuation of the freezer, which does not have a refrigeration function itself. There is no air conditioning in the refrigerator. There should be serious ice clogging in the freezer. It is recommended that after the power outage, take out all the items in the freezer to melt the ice. After the ice clogging problem is solved, power the refrigerator will be restored. The functions of the refrigerator will be restored.
power problems
Sometimes it’s not a problem with the use or the quality of the refrigerator. It may be your power supply. The power supply checks whether the power connection is normal. Open the box door and observe whether the lights in the box are on, or use an electric pen to test whether your socket has electricity.
Compressor problem
If the power supply is connected normally, listen to whether the compressor is working. The compressor will make a slight and vibrating motor sound when working normally (if you feel the vibration of the compressor with your hands, you should be careful not to burn yourself, because the compressor temperature is 40-50 ° C in winter and can reach 80-90 ° C in summer)
Whether refrigerant leaks
If the compressor can work, judge whether there is refrigerant in the refrigeration system. Let the refrigerator run for a few minutes, unplug it, and listen carefully for the sound of liquid flowing in the copper pipes. If not, it means that the refrigerant in the system has leaked or the compressor has lost its ability to work.
Fan problem
If the refrigerator is of the inter-cooled type, check whether the fan is working. Open the door of the freezer room, press and hold the button at the edge of the box opening with your hand (this button controls indoor lighting and stops the fan when opening the door) to check whether the fan is working. If the fan does not work, the refrigerator will not be cooled. In addition, placing too much food will also affect the cooling effect.
Influence of external temperature
Freezing compartments may cause extreme cooling temperatures for refrigerant. Most of this phenomenon occurs in air-cooled refrigerated refrigerators. The reason is that the frosted device of the refrigerator evaporator is broken, causing ice clogging. It cannot be ruled out that the air-cooled fan is broken, and the air outlet is blocked by too many items in the refrigerator, causing poor cooling effect. The temperature of the refrigerator compartment of a direct-cooled refrigerator is automatically adjusted with the temperature of the freezer compartment. You can lower the temperature of the freezer compartment. Generally, the temperature of the refrigerator is 4-10 degrees. Note that the higher the number of the temperature controller, the lower the temperature. The number will be larger in summer and the number in winter will be smaller. In addition, the refrigerator door is often opened, and there are many items in the refrigerator, resulting in the refrigerator not being refrigerated or the cooling effect is unsatisfactory.
