[What should I do if the refrigerator does not cool] What should I do if the refrigerator does not cool and there is a sound of running water?
Analysis of the reasons why the refrigerator does not cool
1. The high-pressure output buffer tube in the compressor is broken, or the screw fixing the tube is loose, resulting in no exhaust from the high-pressure tube and no suction from the low-pressure tube. refrigeration.
2. The refrigeration system leaks and all the refrigerant runs out. Although the compressor is running, there is no refrigerant to evaporate and absorb heat in the system, so the temperature in the refrigerator does not drop.
3. The capillary is blocked, and the refrigerant cannot enter the evaporator to evaporate and absorb heat, so the temperature in the refrigerator does not drop.
The reason why the refrigerator is not cooling and the solution
1. First check whether the power connection is normal, whether the light in the refrigerator is normal, you can also use the Pen for testing. If there is a problem with the power connection, you need to replace the connecting wire, etc.
2. The compressor will emit a small motor vibration sound when it is working normally. If there is no such sound it may be a problem with the compressor. At this time, you need to open the case, replace the new buffer tube, or tighten the screws.
3. After running the refrigerator for 3-5 minutes, cut off the power and listen to see if there is a sound of water flowing. If there is no sound. It means that the refrigerant in the refrigeration system has been used up or leaked. If there is a system leak, find the leaking part of the system, after welding repair, pressure test, and evacuation are qualified, add refrigerant to a certain amount, usually according to the evaporator full of frost or the rated temperature in the refrigerator.
4. Open the door of the refrigerator compartment, press and hold the button at the edge of the box mouth (this button controls the indoor lighting and stops the fan when the door is opened), check whether the fan is working, so as to judge whether it belongs to the capillary tube blocked. Solution: The capillary or the dryer is blocked, and the outlet is hot. For this reason, it must be removed and cleaned!
What should I do if the refrigerator does not refrigerate and there is water running?
The refrigerator has the sound of running water. Turn the switch to on
The effect will be seen after a few hours of emptying. Because the working time of the temperature and low temperature controller to control the compressor is relatively short, the effect will not be good. If it doesn’t work, check to see if the compressor is not working, check the compressor circuit, the compressor’s starter and protector, and the thermostat. If the compressor is working and doesn’t cool down, it may be that there is no freon. Leak detection and fluoride.
Generally speaking, as long as the refrigerator does not leak Freon, there is no need to supplement the refrigerant for life. As long as there is a lack of Freon, there must be a leak. During maintenance, the leak point should be found and repaired. For fluoridation, simple fluoridation is irresponsible and will inevitably lead to secondary maintenance.
There are generally two reasons for this phenomenon:
1. The user does not believe that his refrigerator has leaks, and feels that the refrigerator has been used for many years , the refrigerant should be replenished, this is a wrong concept, and the maintenance personnel are reluctant to explain.
2. Individual maintenance personnel make money by repairing the same fault for many times (it is just an individual phenomenon, but this phenomenon does exist).
