What is the reason why the refrigerator has poor cooling effect? How to solve it?

Refrigerators were still a luxury item in the 1980s and 1990s. At that time, buying a refrigerator would probably cost several years of working people’s wages. Nowadays, refrigerators have entered thousands of households and are also one of the necessary household appliances for families. When we use it, we often encounter refrigerators that do not cool or have poor cooling effects, but we don’t understand the real reason. What are the reasons why refrigerators cannot cool? What should I do if the refrigerator cannot be refrigerated? The following small editor will give you a brief introduction to what to do if the refrigerator cannot be cooled?

The most important components in the refrigeration system of a refrigerator are the compressor, expansion valve, condenser, capillary tube, and evaporator of the refrigerator. The main role of the refrigerator compressor in the refrigerator refrigeration system is to absorb low-temperature and low-pressure refrigerant vapor from the evaporator, and finally becomes high-temperature and high-pressure vapor after adiabatic compression by the compressor. The role of the refrigerator condenser in the refrigerator compressor is to introduce the high-temperature and high-pressure vapor in the compressor into the condenser, condense the refrigerant vapor at the same pressure, and at the same time dissipate heat to the surrounding medium, turning it into high-pressure and low-temperature refrigerant cold liquid.

1. There is too much food in the refrigerator:

There are too many things in the refrigerator and it is full. Others will also put those hot foods into refrigerators. The capacity and power of each refrigerator are rated, and they put in too much food and are overloaded. The cooling effect will definitely not be good.

2. The refrigerator door is not closed properly:

If the refrigerator door is not closed properly, the refrigeration work of the refrigerator compressor is ineffective, so the compressor will always work without stopping, resulting in an increase in power consumption, and the refrigeration effect of the refrigerator will also have an impact, but it will not fail to cool. If the freezer door is not closed properly, thick ice will form between the crack of the door. This is something that everyone should pay special attention to.

3. The refrigerator has poor heat dissipation effect:

Our family refrigerators generally have condensers on both sides of the refrigerator. These sides are hot when the refrigerator is refrigerated. Some families put beautiful decorations on both sides of the refrigerator for beauty. This is very unscientific. The result of doing so will be poor in the refrigeration effect of the refrigerator and the temperature will not reach the set temperature. It will also increase the load on the compressor and shorten the life of the compressor. It should also be noted that there needs to be a gap of more than 5 centimeters on both sides and back of the refrigerator, so that the heat dissipation effect is better.

4. Mechanical refrigerator temperature adjustment is wrong:

The temperature adjustment of the mechanical refrigerator is adjusted by a rotating dial. The larger the corresponding number, the lower the refrigeration temperature of the refrigerator will be, and the greater the load of the compressor will be. In winter, we can compare this number. Big, because winter is here and the ambient temperature is relatively low. We want to freeze food. If the temperature is not adjusted relatively low, the refrigerator will not cool. At this time, we can adjust this number to 4 or 5. You can turn this number higher in summer, either to 1 or 2. 0 means no cooling.

5. How to tell if the refrigerator is really broken:

After we vetoed the above questions, if the refrigerator still does not cool or the cooling effect is not good, we can adjust the refrigerator temperature to the lowest level, and after about an hour, touch the sides of the refrigerator with our hands and touch the back wall inside the refrigerator with our hands. If the sides of the refrigerator do not heat and the back wall inside the refrigerator does not freeze, at this time we can judge that the refrigerator is really broken and we have to seek after-sales maintenance.

Notes: 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. Don’t open the refrigerator door often because it automatically adjusts with the freezer temperature. If you really can’t solve it, hand it over to the maintenance technician to avoid trouble.
