First, the power supply problem: sometimes the lack of refrigeration in the refrigerator is not caused by improper use, nor is there a problem with the quality of the refrigerator. Maybe there is something wrong with your power supply. Check whether the power connection is normal, open the door of the box, observe whether the lighting in the box is on, or test whether your socket has electricity with an electric pen.
Second, the compressor problem: If the power connection is normal, check whether the compressor works. When the compressor works normally, the motor will vibrate slightly. If you feel the vibration of the compressor with your hands, be careful not to burn it, because the temperature of the compressor is 40-50℃ in winter and 80-90℃ in summer.
3. Whether the refrigerant leaks: If the compressor can work, judge whether there is refrigerant in the refrigeration system.
Hazards caused by freezing room:
The freezing room may cause the extreme refrigeration temperature of refrigerant, which often happens in air-cooled refrigerators. The reason is that the evaporator of the refrigerator is frozen and cracked, causing ice blockage. It is not ruled out that the air cooler is broken and the air outlet is blocked by too many items in the refrigerator, resulting in poor cooling effect.
The temperature of the refrigerating chamber of the direct-cooling refrigerator is automatically adjusted with the adjustment of the freezing chamber temperature, and the freezing chamber temperature can be reduced. Generally, it is normal that the refrigerator temperature is 4- 10 degrees. Note that the larger the thermostat number, the lower the temperature, the larger the summer number and the smaller the winter number. In addition, the refrigerator door is often opened, and there are many items in the refrigerator, which leads to the refrigerator being unable to cool or the cooling effect is not ideal.
