Every family will face some big or small appliances problems, some are quality problems, some are small details that need to be slightly debugged. Today, Xiaobian will introduce you to some small problems that are easy to appear in the refrigerator every day, and the corresponding Adjustment measures.

Fault one: the refrigerator is also sweating
When the temperature is high and the humidity is high in summer, water droplets appear around the door of the refrigerator without the anti-exposure device or on both sides of the refrigerator, just like the condensation of water vapor on the wall of the herbal tea cup. This phenomenon is commonly called "drip."
This is a normal phenomenon, and once the weather gets dry, this phenomenon will disappear. However, it should be noted that when the refrigerator appears to be "sweating", it should be wiped clean with a soft cloth in time, and keep the refrigerator as dry as possible. Otherwise, the moisture will adhere to the surface of the refrigerator for a long time, which will corrode the paint surface of the cabinet and affect the appearance.
Fault 2: The refrigerator "high fever"
When the refrigerator is working, it feels very hot when you touch the outer casing by hand, especially in the summer when the ambient temperature is high. Sometimes the surface temperature is as high as 80 °C-90 °C, which is caused by the heat generated by the continuous high-speed operation of the compressor. At the same time, the temperature of the condenser surface can reach 50 ° C -60 ° C (higher in summer), because the refrigeration system is performing heat exchange. These are normal phenomena.
Fault three: the refrigerator "sings"
Starting from the refrigerator compressor, until the refrigerator compressor stops running for 1-2 minutes, the evaporator in the upper part of the refrigerator emits a sound like "squeaking" and "squeaking" like a running water. This sound is the "over-liquid sound" of the refrigerant circulating in the refrigeration system when the refrigerator is working. After the compressor stops working, the refrigerant will still flow for a while because the pressure difference is still large.
Fault four: the compressor does not stop working
When the newly purchased refrigerator was started, the compressor worked for a long time without stopping. This is not a malfunction, because the internal and external temperatures of the newly-enabled refrigerator are the same. To reduce the temperature in the refrigerator, the compressor must work continuously for 5-8 hours. Therefore, it is preferable that the food to be frozen is placed in the freezer after the refrigerator compressor is operated for 3 hours.
