[The freezer is not cooling] The reason why the freezer is not cooling The solution for the freezer not cooling
1. Lack of refrigerant
Most of the double-door freezer capillary outlet is first to the freezer to start the cycle, that is to say, the refrigeration starts in the freezer — and ends in the refrigerator, If the refrigerant is lacking, it is first reflected in the lack of cooling from the refrigerator compartment. If the refrigerant is further insufficient, the freezer compartment evaporator will not be fully frosted. If there is a further shortage of refrigerant, the freezer will not cool.
Second, there is internal leakage in the high pressure section of the refrigeration system of the freezer.
Caused by blisters, cracks, fractures in condensation and anti-dew pipes. If the condenser is not used for a long time, it will rust together with the foaming agent until it leaks or leaks. The strength of the pipe wall at the leaking place is weak, and it appears as a leak under high temperature and high pressure. When the high-pressure pipeline leak is repaired, it is manifested as refilling the refrigerant, and the refrigerant runs out for 1-2 days after starting up, but the leakage is very slow if it is not used when it is shut down.
Three, the freezer freezer freezes.
This situation is also divided into two types. One is that the refrigerator is partially frozen, and other parts are not sticky. This situation is generally caused by insufficient Freon (long-term non-stop). Caused by system plumbing leaks.
The second is that all the refrigerators are frozen, or the system does not stop, mainly because the thermostat fails. Either the refrigerator door is not closed tightly, causing a lot of outside air to enter and produce a lot of frost.
Fourth, the temperature of the freezer compartment cannot be lowered.
1. The compressor is bad, the exhaust pressure of the compressor is insufficient, and the temperature of the radiator is low. The solution is to replace the compressor.
2. The ambient temperature where the freezer is located is too high, and the temperature of the food in the freezer is too high or too much.
3. The frost inside the freezer is too thick. 3. The inner tank is detached, and the poor quality inner tank is deformed or opened, resulting in poor heat conduction with the evaporator.
4. The insulation layer of the box is aging, and the cooling is too much.
5. The fan does not run, and the radiator is too dirty and blocked.
5. The capillary drying filter is blocked, blocked by water separation (ice block) and dirty.
1. Water blockage treatment method: vacuum drainage.
2. Dirty blockage generally occurs at the inlet and outlet of the capillary, and from experience, most of them appear at the inlet of the capillary. Dirty blockage generally causes poor cooling effect. The refrigerant flow is not enough to make the evaporator all frost.
Dirty blockage treatment: replace the filter drier. Judge whether it is at the entrance of the capillary and at the entrance of the outlet: if the filter drier is blocked at the entrance, condensation must occur, that is, the temperature of the filter drier near the capillary is lower than normal temperature.
