The reason why the freezer does not cool:
What is the reason why the refrigerator is not cooled? 1: The exhaust port is blocked.
The refrigerator thermostat is refurbished in the refrigerating compartment, and the temperature of the refrigerating compartment does not reach the temperature required by the thermostat, so it does not stop. If the compressor does not stop working around the clock, the freezer compartment may cause the refrigerant to limit the cooling temperature. Most of this happens in air-cooled refrigerators. The reason is that the refrigerator of the refrigerator compartment evaporator is broken and an ice block is generated. It is also impossible to rule out that the air-cooled fan is broken, and too many items in the refrigerator will block the air outlet, causing a poor cooling effect.
What is the reason why the refrigerator is not cooled? 2: There are too many items in the refrigerator.
The temperature of the refrigerating compartment of the direct-cooling refrigerator is automatically adjusted according to the temperature adjustment of the freezing compartment, and the temperature of the freezing compartment can be lowered. Generally, the temperature of the refrigerator compartment is 4-10 degrees. Note that the higher the temperature controller, the lower the temperature, the higher 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 causes the refrigerator to be uncooled or the cooling effect is not satisfactory.
What is the reason why the refrigerator is not cooling? 3: The compressor is malfunctioning.
The reason why the refrigerator is not cooled may be that there is a problem with the refrigerator compressor. The compressor can be started. When the return air pipe is removed and the outlet is blocked with a finger, the pressure is checked. If the pressure is too low, the compressor has a problem. If the compressor cannot be started, check whether the refrigerator power supply is plugged in.
The solution for freezing the freezer:
1. Cut the boot case, replace the buffer tube, or tighten the screws.
2, first find out the system leakage parts, after welding, pressure test, evacuation qualified, add refrigerant to a certain amount, usually according to the evaporator full of frost or the refrigerator reaches the rated temperature.
3, the capillary or dryer is blocked, the outlet is hot, for this, you must remove it!
In addition, the domestic refrigerator generally has two types of direct cooling type and intercooling type. The direct cooling type means that the evaporator (cooling tube) directly exchanges heat with the freezing and refrigerating chambers for cooling purposes; the intercooling type refers to the evaporator ( The cooling pipe is separated from the freezing and refrigerating compartments, and a fan blows cold air into the freezing and refrigerating compartments for cooling purposes.
