Who knows what to do if the air conditioner can t be cooled?

The main reasons why the air conditioner does not refrigerate are: 1. There is no refrigerant in the air conditioner. 2. The outdoor unit of the air conditioner is faulty, including the compressor of the outdoor unit, which is broken, and the capacitor is burned.

The above reasons are recommended to ask a professional maintenance master to deal with it, if your air conditioner has a local store, you can go to the store to ask the master to solve.

The air conditioner is not refrigerated, and the reasons for such failures are generally as follows: (1) There is a serious dirty blockage in the refrigeration system, which should be removed in time. (2) There is serious ice blockage in the refrigeration system.

3) Residual air or other non-condensable gases in the refrigeration system, resulting in high pressure. (4) The fan does not rotate or the speed is too slow, and the circulating air volume is insufficient. (5) The refrigerant is leaking or seriously insufficient.

6) The high and low pressure valve plates of the compressor are damaged or the paper pad is broken down, and the refrigeration system is difficult to form high and low pressure, so it cannot be refrigerated. (7) After the air conditioner is repaired, the length of the capillary tube to be replaced is too long or too short, and the inner diameter is too large or too small, resulting in a larger or smaller refrigerant flow rate, which affects the refrigeration effect. (8) The air conditioner is improperly installed, and there is a phenomenon of running cold around the box; or exposed to the sun, or too close to a heat source.

9) The air-conditioned room is too large, the door is opened and closed frequently, or there are gaps in the door and window, and the cooling capacity leaks a lot. Users can take different maintenance methods for different reasons. ]

Hehehe, I was in the same situation as you last night, don't worry, it's very simple. The internal machine is normal, the outdoor unit fan blows, how to compress it is not refrigerated, I am sure that it is not without refrigeration, but we are laymen after all, endure being "baked" overnight, the next day the repair machine came, said that the starting capacitor was broken, with five minutes to change one, try it, well, the capacitor is twenty-five yuan, the salary is thirty yuan, and it took fifty-five yuan to return to the cool summer].

The solutions to the sudden failure of the air conditioner include checking whether the compressor is started, checking whether the air conditioner is lacking in fluorine, checking whether the radiator needs to be cleaned, checking whether the voltage is stable, and so on.

1. Check whether the compressor is started.

After the air conditioner turns on the refrigeration, the fan of the external unit is rotating, but there is no cooling effect at all. This situation is most likely due to the fact that the air conditioner compressor is not running.

2. Check whether the air conditioner lacks fluoride.

Fluoride deficiency is the most common reason why an air conditioner does not refrigerate. There are a large number of pipes in the air conditioning and refrigeration system, and the pipe connections cannot be completely free of air leakageAs the running time of the air conditioner increases, some of the refrigerant will slowly leak and the cooling effect will also decrease.

3. Check whether the radiator needs to be cleaned.

Air conditioners require heat exchangers to transfer heat from inside and outside. When the heat exchanger is covered with a large amount of dust, cobwebs and other garbage, it cannot effectively dissipate heat, and the cooling effect of the air conditioner is poor. It is necessary to clean the heat exchangers of the internal and external units.

4. Check whether the voltage is stable.

During peak hours, the power supply voltage is unstable and cannot reach the normal voltage required for the operation of the air conditioner, resulting in the air conditioner not cooling or poor effect. During high temperatures, it is easier for the air conditioner to run at the same time.

Reasons why the air conditioner is not cooling:

1. Too much dust. Because the outdoor unit is exposed to the outdoors, it is easy to absorb dust and debris, and if it is not cleaned for a long time, it will affect the heat dissipation performance of the machine and reduce the refrigeration effect of the air conditioner. In addition, too much dust accumulation through the indoor unit filter screen blocks air circulation, which will also lead to poor external and internal cooling effect.

2. The power supply voltage is too low. The power supply voltage is too low, causing the air conditioner to not be easy to start, this is not a fault, as long as the power supply is checked, it is the power grid voltage is too low, the user should install a power regulator, so that the voltage reaches 220V, so that the air conditioner can be used normally.

3. The problem of the compressor. The problem of the compressor, the use of the compressor is too long, the compressor is aging, the efficiency is not enough to decline before, like the sound of the air conditioner, the vibration is relatively large, you need to consider whether the compressor problem, such problems can only find professionals for maintenance, or consider buying a new machine.

4. Lack of refrigerant. The air conditioner uses freon as the refrigerant, and the refrigerant will volatilize, and if the air conditioner is not installed properly, it will also cause refrigerant leakage. This situation generally occurs after the air conditioner has been used for a period of time, and you will find that the cooling effect of your home air conditioner is not as good as before.

If the air conditioner lacks refrigerant, it should be added in time.

Check if the compressor of the air conditioner is working properly. The compressor of the air conditioner is one of the most important components in the refrigeration process, and if it fails, it will affect the cooling effect of the entire air conditioner. Check if there is a problem with the electronic circuitry of the air conditioner.

The electronic circuitry of the air conditioner may malfunction, which will affect the normal operation of the air conditioner.

What's the deal with the air conditioner not cooling? Let's find out.

1. The indoor unit or outdoor unit is not running

First of all, check whether the Chigo air conditioner is operating normally, including the indoor unit and the outdoor unit, especially to check the compressor of the outdoor unit, as long as one of them is not running normally, then you have to ask a professional to repair it.

2. The air filter is blocked

Due to the long-term use of the air conditioner, there is no regular cleaning to cause the filter to be blocked, and the sediment accumulates more and more for a long time, which eventually leads to the air conditioner not being refrigerated.

3. Insufficient refrigerant for air conditioning

The biggest possibility is that the air conditioner has no refrigerant or the refrigerant is insufficient, at this time we can ask professionals to come and add refrigerant to guess the pants.

4. There is a problem with the source or voltage of the electric distribution

Power supply or voltage problems this phenomenon is more common in summer, because in the hot summer electricity consumption is relatively large, seriously exceeding the electricity load, it will lead to air conditioning is not cooling, in this case Suijian also has no better way, at most is to negotiate with the local property to increase the rated power of electricity, and then there is to buy a better voltage regulator.

The above is today's sharing, I hope it can help you.

Tips:

Summer is coming, I believe that many friends in the hot summer are inseparable from air conditioning, and the strength of air conditioning determines the happiness of summer, many friends in the air is not cooling, the first reaction is the need to add fluoride, in fact, no, because the reason for air conditioning is not refrigeration is not necessarily the lack of fluoride, small partners try these tricks first.

The placement of the air conditioner outside is unreasonable.

If the air conditioner is not refrigerated or the refrigeration efficiency is low, it is also possible that the outdoor unit is placed in a relatively closed space, resulting in the air field not circulating, or the temperature around the outdoor unit is continuously too high, resulting in the heat emitted by the radiator cannot be dispersed as soon as possible, resulting in the air conditioning refrigeration is not working, so the installation of the outdoor unit must be ventilated and a cool place.

Clean the room through the strainer or fins.

If the air conditioner is not cleaned for a long time, it is easy to accumulate dust, breed bacteria, produce peculiar smells, endanger health, and also lead to a decrease in refrigeration performance, which is due to excessive dust attached to the heat exchange fins, which seriously affects the frequency of cold and heat exchange, and the most significant performance is that the air conditioner is not refrigerated. Therefore, the home air conditioner must be cleaned regularly. It can not only ensure air conditioning and refrigeration, but also ensure that the air is clean and clean, and take care of your health.
