Why is the top of the refrigerator not cold?

The refrigerator may have become an indispensable device for every household. Nowadays, people's living conditions have improved, and there is more food on the table, and there is often no leftovers. In this case, you need to refrigerate the food to prevent it from spoiling. Sometimes people will find that the top of the refrigerator is not cool. In this case, people need to find out the reason and then take measures. Here we will introduce why the top of the refrigerator is not cool.

Why is the refrigerator not cooling?

1. Or use a tester to test the power cord. A broken power cord of the refrigerator is also a reason for the failure to refrigerate. In this case, we need to check whether it is a power supply problem. The general practice is to open the door and observe whether the light inside the box is on. Check the wires for signs of damage, such as from being chewed by mice.

2. Lack of refrigerant causes the refrigerator to fail to refrigerate: In most double-door refrigerators, the capillary tube outlet first enters the freezer to start circulation, that is, refrigeration starts in the freezer and ends in the refrigerator. If there is a lack of refrigerant, it will first manifest itself in a failure to refrigerate in the refrigerator. If the refrigerant is further insufficient, the freezer evaporator will not be able to be completely frosted. When the air pipe outlet is blocked, it will cause cooling problems.

3. Frost in the evaporator causes the refrigerator to fail to refrigerate: When the frost on the evaporator cannot melt, it blocks the air duct opening. This is mainly because air-cooled refrigerators usually have only one evaporator, and the cold air cannot escape, causing the refrigerator to fail to refrigerate. At this time, you need to check the defrost system. The defrost timer may be faulty or the heating tube may be burned out.

How to solve the problem of refrigerator not cooling?

1. Regarding the compressor problem, we need to check the pressure at this time. If it is too low, then there is a problem with the compressor. The compressor cannot start. Check whether the refrigerator power supply is properly plugged in. If it is blocked, remove the blockage and it will return to normal. If it is a problem with the compressor itself, the compressor needs to be replaced.

2. Note that the larger the number on the temperature controller, the lower the temperature. The number should be larger in summer and smaller in winter. In addition, the refrigerator door is often opened and there are many items in the refrigerator, which causes the refrigerator to not cool or the cooling effect is unsatisfactory. The temperature of the refrigerator compartment of a traditional mechanical temperature-controlled direct-cooling refrigerator is automatically adjusted along with the temperature of the freezer compartment. You can simply lower the temperature of the freezer compartment. Generally, the normal temperature in the refrigerator is 4-10 degrees. If the fan of the refrigerator fails, the fan needs to be repaired. In serious cases, the refrigerator fan needs to be replaced. At the same time, the refrigerator air outlet should be cleared to ensure the smooth flow of the air outlet, increase the heat dissipation effect of the refrigerator, and reduce the internal temperature of the refrigerator.

3. Sometimes it is easy to accidentally adjust the refrigerator's thermostat, causing the temperature inside the refrigerator to rise and the refrigerator's refrigeration effect to weaken. When using the refrigerator, it is easy to have the illusion that the refrigerator is not cooling. At this time, you need to readjust the refrigerator's thermostat. In winter, the thermostat gear needs to be adjusted higher. In summer and winter, the thermostat gear adjustment is just the opposite. In summer, the refrigerator thermostat needs to be lowered.
