There are three reasons why Rongsheng refrigerators do not refrigerate

Refrigerator has become one of the indispensable appliances in people's daily life, if the refrigerator is not refrigerated, resulting in the food inside is not fresh or spoiled, then pay attention to the following points.

1. Check whether the refrigerant in the refrigerator is leaking due to the failure of the condenser tube, if this is the case, it is recommended to ask a professional master to repair the condenser tube and add an appropriate amount of refrigerant.

2. Check whether the filter of the refrigerator is clogged due to too many impurities. Impurities on the filter screen can make the refrigerator more burdensome to run and unable to operate properly, which will lead to poor refrigeration. It is recommended to clean the lower filter regularly.

3. Check whether the air outlet in the refrigerator is blocked. Sometimes too much food will block the air outlet, which will cause the refrigerator to dissipate heat poorly, so that the temperature inside the refrigerator will rise, which will greatly reduce the cooling effect. It is advisable to leave enough space for the air outlet of the refrigerator.

The above points are simple situations that we can find or solve by ourselves, if we encounter problems such as refrigerator motors, compressors, thermostats, these circuit knowledge problems cause the refrigerator not to refrigerate, then we must ask a professional master to repair, we must not disassemble it at will, so as not to cause greater losses and unnecessary accidents!

Answer; 1. The refrigerant has leakage points, and 2. The compressor is inefficient. 3. The heat dissipation efficiency of the condenser is low.

There are three reasons why the refrigerator is not cold, one is that the compressor is broken, the second is that the refrigerant in the compressor has a problem, and the third is that the power supply part connected to the compressor is open.

Hello, dear. There may be several reasons why the cold compartment of the Rongsheng refrigerator is not cold and slippery:1

The temperature setting is incorrect. Please make sure you set the temperature correctly. At room temperature, the temperature should be between 2-8 degrees Celsius.

If the temperature is set too high, the temperature inside the refrigerator will not be controllable, resulting in the refrigerator room not being sensitive to liquid cold anyway. 2.The refrigerator door is not tightly sealed.

Check the door gasket for damage and any air leakage. Replace the gasket if needed. Poor sealing will cause the cold air to be lost, resulting in insufficient air conditioning and the refrigeration room losing its refrigeration effect.

3.The condenser filter screen is too dirty. After long-term use, the filter on the condenser may clog or accumulate a large amount of dirt, resulting in a decrease in cooling effectiveness.

The condenser filter should be cleaned and replaced regularly. 4.Blocked air ducts.

Check that the air duct behind the refrigerator compartment is clean and that there are no items or dirt blocking it, and if so, clean the air duct. 5.Refrigerant leaks.

1. Power line problem.

Fault phenomenon: no refrigeration.

Reason analysis: power on, the internal machine works normally, observe the external machine, the press starts the "hum" sound, can not start normally, the voltage is reduced from 230 volts to 138 volts, the press is protected, the power supply is identified as a problem, check the user's power socket, and find that the decorator uses the grounding wire as the zero line, and the test machine is normal after processing.

Solution: Connect the ground wire with the neutral wire.

Experience summary: installation must be terminated with n neutral wire, can not be replaced by grounding wire, ground wire and neutral wire reversed, but also may cause air switch tripping, new installation of this problem to focus on checking the power supply, sometimes the power cord is too thin, the air conditioner starts when the current is large, and the large voltage drop on the wire will also cause difficulty in starting. In addition to power cord issues, the size of the air switch often causes start-up trips.

2. The external filter is dirty and blocked.

Fault phenomenon: no refrigeration, frequent start and stop of the outdoor unit.

Cause analysis: door-to-door maintenance, no refrigeration, frequent start and stop of the outdoor unit, indoor function can operate normally by remote control, but the outdoor unit starts and stops in about three minutes, and the air outlet is not cold within three minutes, which is preliminarily judged to be a refrigeration system failure, and the pressure on the low pressure side is tested with a pressure gauge, because the equilibrium pressure is at the time of shutdown, and gradually decreases to the equilibrium pressure after the shutdown after starting, and when the external machine is running, it is found that all the frost from the filter to the capillary to the high-pressure pipe is frosted, which can be concluded that the filter is dirty and blocked.

Solution: After replacing the new filter, everything is normal in the test machine.

Lesson summary: For the failure of frequent start-up of the external unit, the first thing to confirm is the circuit fault or the fault of the refrigeration system. Generally, the following phenomena will occur when the filter is blocked:

Frost at the capillary outlet, local frost in the evaporator, detection of low pressure pressure is lower than normal, high pressure pressure is slightly lower than normal pressure, shutdown equilibrium pressure is close to the saturation pressure at ambient temperature, compressor discharge temperature and casing temperature increase. When encountering a large current, the tripping phenomenon is not necessarily the compressor failure, the fault phenomenon should be considered comprehensively, and the current and maintenance pressure should be checked when the general air conditioner is maintained.

3. The connecting pipe of the hair is leaking.

Fault phenomenon: no refrigeration.

Reason analysis: the user reported that there was no refrigeration, after checking that the indoor and outdoor units were running, excluding the phenomenon of poor contact, when detecting the operating pressure, it was found that the operating pressure of the outdoor unit was negative pressure, and there was no fluorine leakage at the pipe joints of the internal and external machines, and no leakage was found in the internal evaporator and the external machine.

Solution: After repair welding, press again without leakage, and work normally after vacuum and quantitative fluorine.

Lesson summary: When some leakage points are difficult to find inside and outside, special attention should be paid to the evaporator connecting pipe, which is very hidden and often difficult to find.

At this time, you can call the after-sales service and make an appointment with service personnel to carry out door-to-door maintenance.

1) Cause analysis 1. The high-pressure output buffer pipe in the compressor is broken, or the screws fixing the tube are loose, resulting in the high-pressure pipe not exhausting and the low-pressure pipe not suctioning, so although the compressor is running, it is not refrigerated. 2. The refrigeration system leaks, the refrigerant runs out, and although the compressor is running, there is no refrigerant evaporation and heat absorption 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, and the temperature in the refrigerator does not drop.

2) Exclusion method 1: Cut the casing, replace the buffer tube, or tighten the screws. 2. Find out the leakage part of the system first, and add refrigerant to a certain amount after passing the welding repair, pressure test and evacuation, usually according to the evaporator is full of frost or the refrigerator reaches the rated temperature. 3. The capillary tube or dryer is blocked, and the outlet is hot, so remove it to remove it!

In addition, there are generally two types of household refrigerators: direct cooling and intercooling, which refers to the heat exchange between the evaporator (cooling pipe) and the freezing and refrigeration rooms to achieve the purpose of cooling; Intercooling means that the evaporator (cooling pipe) is separated from the freezing and refrigeration room, and the cold air is blown into the freezing and refrigeration room by a fan to achieve the purpose of cooling.

If the refrigerator reaches the set temperature and shuts down, the intermittent protective shutdown of the refrigerator compressor is likely to be due to the abnormal state of the refrigerator refrigeration system or the abnormal state of the refrigerator compressor starter.

When there is a certain degree of leakage of refrigerant in the pipeline of the refrigerator refrigeration system, and the amount of refrigerant is insufficient, the refrigerator compressor will intermittently overheat and shut down. At this time, it is necessary to temporarily deactivate the refrigerator and provide after-sales warranty to the refrigerator manufacturer. If you continue to use it for a long time, it is easy to cause the refrigerator compressor to burn out.

1.Refrigeration system failure: The refrigeration system of Rongsheng refrigerator includes compressors, condensers, evaporators, refrigerants and other components, if any of these components fail, it will cause the refrigerator to not refrigerate.

2.Temperature controller failure: The temperature controller of Rongsheng refrigerator is responsible for controlling the temperature inside the refrigerator, if the temperature controller fails, it will cause the refrigerator to not refrigerate or the temperature of the banquet is too low.

3.Pipe blockage: If there is a blockage in the refrigeration pipe of the Rongsheng refrigerator, it will lead to poor refrigeration effect or complete failure. This is usually caused by the accumulation of too much ice or debris inside the pipes.

1. The high-pressure output buffer pipe in the compressor is broken, resulting in the high-pressure pipe not exhausting and the low-pressure pipe not suctioning, so the compressor does not refrigerate although it is running. 2. The refrigeration system leaks, although the compressor is running, there is no refrigerant evaporation and heat absorption in the system, so the temperature in the refrigerator does not drop. 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.

Expand your knowledge: How to eliminate refrigerators that don't refrigerate.

1. When the Rongsheng refrigerator is not refrigerated, you first need to check whether the compressor of the refrigerator is starting normally. In summer, the compressor cannot start normally because the temperature of the compressor is too high and the line is burned out, resulting in the compressor not running normally.

First of all, check whether the power cord of the compressor is burned out, the circuit of the compressor needs to be replaced again, and at the same time remove the debris around the refrigerator, so that the refrigerator can have good heat dissipation and reduce the temperature of the refrigerator compressor.

2. The long-term operation of the compressor leads to the reduction of the temperature limit in the refrigerator, resulting in the extreme refrigeration of the refrigerator, and at the same time, the defroster in the refrigeration room of the ice shirt box fails, which makes the refrigerator collapse and ice blockage, and the ability of the refrigerator to dissipate heat and defrost decreases, and the refrigeration effect of the refrigerator is reduced.

If the refrigerator defroster fails, you first need to turn off the power of the refrigerator to clean up the frost in the refrigerator, and then replace it with a new refrigerator defroster, and dredge the exhaust outlet of the refrigerator, so that the refrigerator can be defrosted and drained normally, and the refrigeration effect of the refrigerator will be restored.

3. When the Rongsheng refrigerator is not refrigerated, you need to check whether the power cord of the refrigerator is connected well and whether there is any loosening. If the power cord of the refrigerator is not plugged in properly or is loose, the refrigerator will definitely not be able to refrigerate. If the power cord of the refrigerator is loose or not plugged in, you need to plug the power cord of the refrigerator back in to ensure that the power supply is smoothly energized.

Generally, we will always encounter all kinds of problems in our daily life, and the problem we encounter in summer is that the refrigerator at home is not refrigerated, if the refrigerator at home does not have any refrigeration function, the meat and vegetables at home will be swished off, and we can not enjoy the summer food. No matter what brand will not refrigerate, such as Rongsheng refrigerator, it will also have such a phenomenon, so what is the reason for this situation? How do we solve it?

Let's take a look at the introduction to you!

First, the reason for not refrigerating.

1. The problem of the compressor.

To see why it is not refrigerated, you can see whether the output buffer pipe in the compressor of the refrigerator is broken, or whether the fixed screw is loose and the air pressure pipe does not exhaust or suction, and also depends on whether the refrigeration system leaks.

2. Caused by obstruction.

There are a lot of tubes in the refrigerator, let's see if there is a blockage in the capillary, because if there is a blockage in this position, it will also cause the refrigerant to not enter the evaporator for heat absorption, so that the temperature of the whole refrigerator will also rise, resulting in it not cooling.

Second, the solution introduction.

1. Check the power supply with an instrument.

We dig open the refrigerator door to see if the lights inside are on, and also make sure that its power supply is turned on, etc., we can use an electric pen or multimeter to check the socket, the normal voltage of the refrigerator is between 187V-242V.

2. Look at the ambient temperature.

Generally, our temperature control has a control range, if the temperature we control is lower than our normal starting temperature, we need to check whether the refrigerator temperature switch is turned on, because in order to ensure that the temperature controller is working.

3. Add refrigerant.

Many times, the refrigerator does not refrigerate because the refrigerant in it is gone, we can open the inside of the refrigerator, replace the buffer tube, check whether the refrigerant is leaking, and add some refrigerant to let the refrigerator refrigerate.

4. Use the form of refrigeration.

There are many forms of refrigeration in refrigerators, our household refrigerators have direct cooling and intercooling two, the former is directly frozen by the evaporator, and the latter needs to be separated, we can use the fan to push the cold air to freeze, so as to ensure the refrigeration of the refrigerator.
