Why does the refrigerant of the car air conditioner stop cooling within two days of adding it?

1. The zero live wire of the air conditioner power supply is reversed;

2. The fan or capacitor of the internal or external unit is damaged;

3. Refrigerant leakage or poor refrigerant quality;

4. The compressor capacitor is damaged or defective.

This fault is obviously due to the leakage of the refrigerant.

The car repair master did not find the leakage point and helped you add the refrigerant, which caused the refrigerant to leak after two days, of course, it was not cold.

Similar to many household split air conditioners.

To check the connection pipe, if there is any leakage. The pressure can be maintained to fill the refrigerant.

The air conditioner's power supply is reversed.

Main performance: Generally, it will only appear when the car air conditioner is installed.

Workaround: Reconnect the neutral wire.

The fan or capacitor of the internal or external unit is damaged.

Main performance: If the external fan is broken, the main manifestation is that the exhaust temperature is too high or the high pressure is too high; If the internal fan is broken, it will be frosted in the internal unit.

Solution: Replace the damaged internal (external) fan or capacitor.

Refrigerant leakage or poor refrigerant quality.

Main performance: The internal and external units of the car work, and the compressor also works, but the car air conditioner has no refrigeration effect.

Solution: Check whether it is caused by leakage or quality problems of refrigerant in automobile air conditioning, and add or replace refrigerant in time.

Damaged or defective compressor capacitors.

Main performance: The internal and external units of the car are working, the compressor will not rotate, and it will cause overheating.

Solution: Check whether the compressor capacitor is in poor contact or damaged, and replace it in time if damaged.

The air conditioner is not refrigerated, mainly when the temperature is set in the low temperature gear and the A C key is turned on, after a period of time (the length is different according to the type of car and the service life) it is found that the air temperature from the air outlet does not meet the expectation or does not change, this fault phenomenon is that the air conditioner is not refrigerated, and the possible reasons for this fault phenomenon are as follows:

When the air conditioning fluid is insufficient or there is no air conditioning fluid, it will lead to insufficient liquid pressure in the air conditioning pipe (two silver-white aluminum pipes in the front cabin, the large diameter is the low-pressure pipe, and the small one is the high-pressure pipe) The liquid pressure is insufficient, and the compression pump cannot be driven for refrigeration. If there is a gas pressure relief sound and condensation mist, if there is a statement that the air conditioning fluid in the pipe is normal, if not, the air conditioning fluid in the pipe is insufficient, you need to judge the leakage point and refill the air conditioning fluid, at this time it is more appropriate to go to a professional 4S shop or maintenance shop;

The compression pump does not work, in addition to the lack of pressure of the above-mentioned air conditioner fluid, it may also be the cause of the pump itself, the compression pump fails to work, under normal circumstances, when the A C key is turned on for refrigeration, the sound of the buzzing pump working can be heard in the front cabin in the car, and this kind of fault can only be troubled by professional maintenance personnel;

Failure of electrical components, such as failure of the A C key, failure of the pressure switch, etc.

What is the problem with the car air conditioner and refrigerant for a week, it is very likely that there is a problem with your air conditioner itself, which may be bad. Then you go to the repair shop where you refrigerated before.

This may be caused by leakage in the refrigerant pipeline, and there may be a problem with the refrigeration compressor, which needs to be checked and repaired in time.

That means that the location where the refrigerant is stored is leaking. A lot of the refrigerant has escaped into the air. At this time, it is time to inspect the refrigerant storage equipment of the vehicle and then repair it.

After adding refrigerant to the motor vehicle air conditioner, the effect is obvious, and the phenomenon of no refrigeration is found in a week, which is mainly caused by the leakage of the storage tank of the refrigerator.

After a few days of fluoride refrigeration in the car air conditioner, what happens if it is not refrigerated? The power supply voltage is not enough, the power of the air conditioner is not enough, and the external ambient temperature is too high.

In this case, it should be that there is a leak in the air conditioning system, which causes the refrigerant to leak again after being used for a few days after fluoride is charged. Before filling freon, vacuum and hold pressure for at least 12 hours to confirm whether there is any leakage in the system.

Hello! According to your description, you said that the air conditioner has a cooling effect after adding refrigerant, but after a few days, the cooling effect decreases, right?

Normally, the refrigerant may have been missed. But if you don't find the leakage, then you have to judge whether the refrigerant leaked. If the pressure is not right, the leakage detection pipeline, and the pressure is normal, it means that the refrigerant is not missing, and other problems need to be checked to see whether the compressor is working normally, whether the high-pressure switch is normal, and the cause of the problem needs to be determined first for the maintenance of the air conditioner.

Hope it helps!

Summary. Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Hello, I am your dedicated service technician. I will answer your questions with heart and attention. Reasons why the air conditioner can't be added The air conditioner pressure switch is damaged, and the pressure sensor needs to be replaced.

If the air conditioner pump is damaged, if the air conditioner pump plug has electricity, replace it directly. Some cars come with an economic mode and need to be closed. The air conditioner panel is damaged.

It's the air conditioning pump that's working, it just doesn't suction.

That's for the air conditioning pump.

The clutch that turned on the air conditioner pump kept turning, but it couldn't add refrigerant.

That's internal wear and tear.

Wear and tear on the inside, can the exterior also work?

Yes. Just after vacuuming, when I turned on the air conditioner, I saw that his clutch was sucking at work, but it just couldn't add refrigerant, and the low-pressure pipe was not cold.

Well, change the air conditioning pump.

Could it be a pressure switch or some kind of external temperature sensor or something.

No. At first, I could add a bottle, but the pressure gauge didn't respond and didn't move.

Air conditioning pump problems.

If I can help you, please give me a thumbs up Thank you!

Even if there is a problem with the refrigeration system inside the car, it is also because it has not been used for a long time or has a failure due to frequent use.

It may be because there is something blocked in the air conditioner, or the air conditioner is blocked due to not cleaning the air conditioner for a long time, you can send it to the car maintenance department to repair it.

It is very likely that the vehicle's air conditioning and refrigeration system has failed, and the refrigerant is insufficient, so minor repairs can be made.

It could be because the air cleaner is blocked, or there is a problem with the system, or the air conditioner flap is broken.

The reasons why the car air conditioner does not refrigerate for a week without refrigeration are as follows. 1. The refrigerant leakage of the refrigeration system leads to the poor effect of the refrigeration shed, the thermal protection caused by the increase of exhaust temperature, etc. 2. The compressor, fan and its capacitor and other circuits are damaged, resulting in the protection or non-working of the compressor.

3. The refrigeration system is blocked, resulting in poor refrigeration, compressor protection and other failures. 4. Improper installation or too poor working environment, the temperature of the external machine is too high, and the external machine exceeds the normal working environment, etc. <>

I hope I can bring you a banquet to help, thank you, and have a good life.

1.The refrigerant has been added. When the car is driving at high speed, the speed is fast, the pressure of the refrigeration system is high, the pressure controller (pressure switch) acts, the compressor stops, and the air conditioning and refrigeration stop at this time.

When the car is driving at low speed, the speed is slow, the pressure of the refrigeration system is low, the pressure is closed, the compressor works, and the refrigeration is restored. So refrigeration comes and goes.

2.Lack of Frion. The reason for this situation is generally that there is a leak in the pipe in the air conditioning system, at this time, you can drip some water at the refrigerant pipe joint of the car, and bubbles will appear in the leakage place, just find the leakage and repair it.

Then remember to go to a car repair shop or a 4S shop to add some freon.

3.The filter is too dirty. You can try to find the bypass valve on the base of the filter element of the filter, when the pressure difference between the two sides of the valve reaches a certain value, it can be opened, generally the oil flows into the main pipe through this pipe, use the special lubricant for the car to lubricate other related parts, so that the situation will be improved.

4.Caused by the aging of the air conditioner filter. If your cabin air filter is taking a lot of time, then there may be a problem with the cabin air filter.

You can go to the ** or auto parts store by yourself, buy a filter cartridge and replace it yourself. If not, you can find a professional car maintenance shop or 4S shop for replacement.

Because the air conditioner has a constant temperature function, when the air conditioner is cooling, the refrigeration of the air conditioner will stop when the set temperature is reached. When the temperature in the room is greater than the set temperature, the air conditioner starts to cool again. It is also possible that the refrigerant of the air conditioner is running out, so it will feel cold for a while and not cold for a while when it is running.

Questions. The new air conditioner exhausts the air for a while, and it will not be refrigerated for a while, and the hot air comes out of the external unit at the beginning, and then the cold air comes out after a while, and the outer pipe becomes hot from the cold, and the inner pipe does not produce water.

Hello are you still there? It was a new air conditioner that had just been installed in the afternoon.

Hello. In.

Questions. What is the situation, please.

What degrees is the temperature you set. Questions.

22 have tried.

Are the indoor and outdoor compressors working properly.

Questions. Normal rotation, at the beginning of the cold is not cold in a few minutes, the external machine rotates the hot air becomes cold air, and the pipe is not icy.

Then there's the number of air-conditioners you have and the size of the room.

It is recommended that you turn up the temperature a little.

The difference between the indoor temperature and the outdoor temperature is too great, and it may also cause different degrees of impact.

The temperature of the two is best within 10.

In addition, the number of air conditioners does not match the size of your room, which can also happen.

The reason is that when the temperature is higher than the set value, the compressor runs and sends out cold air, and the room temperature decreases. When the temperature falls below the set value, the compressor stops running. The wind that comes out is the hot air.

When using this air conditioner, do not put the air outlet at the area where people are moving, it will be very uncomfortable. A variety of faults can cause the air conditioner to cool down for a few minutes, followed by natural or hot air.
