The compressor runs, but it does not refrigerate, and there is the sound of running water. Is there

The refrigerant is insufficient, there is a sound of running water indicating that there is already air in the pipeline, that is to say, the refrigerant is consumed, you should be seriously insufficient in refrigerant, can not reach the amount required for refrigeration, so it cannot be refrigerated.

Nowadays, there are many varieties of air conditioning refrigerants, such as R22 and R A, which are more commonly used, and 410A is a refrigerant in mixed proportions, and the operating pressure is relatively high, which is easy to cause leakage. Refrigerant supplementation may not have an effect, and it will only have an effect if it is refilled after vacuuming.

This is because one of its refrigeration systems has failed, and it cannot start the refrigeration effect, and it needs to be inspected and repaired.

The compressor operates, but there are two phenomena of non-refrigeration and intermittent non-refrigeration, and the failure reasons for the failure of always unrefrigeration are: first, the connection part of the connecting pipe and the outdoor unit and the indoor unit is leaking; the second is the leakage of the condenser; the third is the leakage of the evaporator; Fourth, the compressor is abnormal. This fault can also occur due to a leak in the four-way valve of the air conditioner.

The main reasons for intermittent non-refrigeration failures are: first, ice plugging or dirty blockage caused by capillary abnormality; The second is that the filter is abnormal, causing ice blockage or dirty blockage. For the fault of never refrigerating, check whether the above parts are leaking in turn, and if so, add refrigerant after treatment; If it is normal, check the compressor, and for ice plugging or dirty blockage faults, after replacing the capillary or filter, and adding refrigerant, it can be eliminated.

The refrigerator is gone, there may be a leak, or it may be that it needs to be added for a long time. At this time, although the compressor of the refrigerator is still running, there is no refrigerant in the refrigeration system for evaporation and heat absorption, so the refrigerator cannot be refrigerated. You can unplug the refrigerator after running for a few minutes, and then listen carefully to see if the sound of water retention is normal, if not, it may be that the coolant is leaking or reduced.

At this time, it is necessary to first check whether the leakage is caused by the damage of the internal pipeline, if the pipe is not damaged, then adding the coolant to the standard value can solve the problem. In addition, it may also be caused by the following situations: 1. It may be the sensor of the refrigerator temperature control.

Check whether the sensor parameters in the uncooled temperature zone are normal, if not, you need to replace the sensor with a new one. 2. You can check whether the waterproof thin pipe in the refrigerator is blocked by foreign objects, if the refrigerator can sometimes be refrigerated and sometimes cannot be refrigerated, it is generally because the ice blocks the sewer pipe, resulting in insensitive or abnormal temperature control, at this time, you need to take out the foreign body that blocks the pipe. 3. The refrigerator compressor is faulty.

When the compressor is working normally, it will emit a relatively slight vibration motor sound, when you put your hand on the refrigerator shell, you can feel the vibration of the compressor, if the vibration is abnormal or irregular, you can judge that it is caused by the failure of the compressor, call customer service for maintenance** and let the after-sales personnel come to repair.

1. It may be a power supply problem, check whether the power connection is normal. Open the door and observe whether the lights in the box are lit, or use an electric pen to test whether the socket has electricity.

2. If the power connection is normal, listen to whether the compressor is working. The compressor will emit a slight vibration motor sound when working normally (if you feel the vibration of the compressor with your hands, you should be careful not to burn, because the compressor temperature is 40-50 in winter and 80-90 in summer).

3. If the compressor can work, judge whether the refrigeration system has refrigerant. Let the refrigerator run for a few minutes before unplugging and listen carefully for the sound of liquid running inside the copper tube. If not, it means that the refrigerant in the system has leaked, or the compressor has lost its capacity.

4. If the refrigerator belongs to the intercooled type, check whether the fan is working. Open the door of the freezer compartment and press and hold the button at the edge of the box mouth with your hand (this button controls the indoor lighting and stops the fan from working when the door is opened) to see if the fan is working, as the fan does not work will cause the refrigerator to not refrigerate. In addition, too much food can also affect the refrigeration effect.

5. The freezer may cause the refrigerant to limit the refrigeration temperature. Most of this phenomenon occurs in air-cooled refrigerators. The reason is that the evaporator flower froster in the cold room is broken, which produces an ice blockage.

It cannot be ruled out that the air cooling fan is broken, and there are too many items in the refrigerator to block the air outlet, causing poor cooling effect.

6. The temperature of the refrigerator of the direct cooling refrigerator is automatically adjusted with the temperature adjustment of the freezer, and the temperature of the freezer can be lowered. Generally, the temperature of the refrigerator room is 4-10 degrees Celsius. Note that the higher the number of the temperature controller, the lower the temperature, the higher the number in summer and the smaller number in winter.

In addition, the refrigerator door is often opened, and there are many items in the refrigerator, resulting in the refrigerator not being refrigerated or the refrigeration effect is not ideal.

Sometimes the compressor of the refrigerator is running, but the refrigerator compartment is not. It is possible that the refrigeration system of the refrigerator leaks, and all the refrigerant leaks, and there is no refrigerant evaporation and heat absorption in the system, resulting in the temperature in the refrigerator does not drop, and the refrigerator room does not refrigerate.

Sometimes the temperature in the refrigerator is not well adjusted, and the refrigerator door is often opened, and there are more things in the refrigerator, which will also lead to the refrigerator refrigerator not being refrigerated or the refrigeration effect is not ideal.

Hello Answer! I have seen your answer, please wait patiently for a few minutes to ask you this question, I have seen this question, don't worry, wait a minute, in the next 5 minutes, I will answer the question you raised, 3. The capillary is blocked, the refrigerant cannot enter the evaporator to evaporate and absorb heat, and the temperature in the refrigerator does not drop. In general, the capillary or dryer is clogged and the outlet is heated. The casing needs to be cut, the buffer tube replaced, or the screws tightened.

The leakage part of the system is found first, and after the welding repair, pressure test, and evacuation are qualified, the refrigerant is added to a certain amount, which is usually subject to the frost in the evaporator or the rated temperature in the refrigerator.

1. The indoor temperature of the refrigerator is too high, resulting in fluorine leakage in the refrigeration system, that is, there is no refrigerant, which causes the tank compressor to work with water flow sound but not refrigeration. 2. Frost in the evaporator, because there is only one evaporator in the air-cooled refrigerator, if the evaporator frost cannot be melted and the air duct mouth is blocked, the cooling capacity cannot go out. 3. The refrigerator has been used for a long time, and there can be a leakage point in the pipe or evaporator, which causes the tank compressor to work with water flow sound but not refrigeration.

Suggested Treatment:

1. First check whether the lighting in the box is on, to determine whether the power supply of the refrigerator is on, if the light is on, it means that the power supply is correct, you can check the next step, if the light is not on, then use a pen or a multimeter to check whether the socket of the power supply has electricity, and whether the power plug of the refrigerator is well plugged in.

2. Check the power supply voltage with a multimeter if it is lower than 187 volts, because the normal use voltage of the refrigerator according to the national standard is 187V-242V, and the compressor of the refrigerator below 187 volts cannot be effectively started normally, resulting in the refrigerator compressor working with water flow sound but not refrigeration, if the voltage shows 220V, it means normal, if it is not between 187V-242V, it is a voltage problem.

3. When the ambient temperature is lower than the normal starting temperature of the temperature controller, check whether the low temperature switch of the refrigerator is turned on.

4. Smell whether there is any abnormal smell in the electrical components of the refrigerator in use, such as the smell of the laughing liquid such as Jiao Xuan to judge whether the electrical components are damaged, whether the wiring is loose and ignited, and clean the box in time, especially the corruption in the freezer corrodes the surface of the evaporator, causing the leakage of the evaporator, and it is difficult to maintain, so it is necessary to find the leakage point for maintenance.
