What is the reason why Midea s air conditioner is not cooling?

1. Freon is not enough (commonly known as not enough refrigerant).

Solution: Supplementing refrigerant can solve the problem of air conditioning not refrigerating, most of the reasons for this non-refrigeration are in the air conditioning that has been used for three or four years, most of them are also a normal phenomenon, which belongs to the normal consumption of air conditioning refrigerant (that is, we often say freon or refrigerant) after long-term use, but this is only manifested as insufficient refrigeration of the air conditioner compared with the previous normal situation, and will not be completely uncooled.

Because the pressure is not enough, it will not be too far from the normal value, as long as you find a regular maintenance network to make up for it; Of course, there are also refrigerant leaks due to installation reasons or the machine itself, which is a common and relatively easy to find reason, and this kind of problem is relatively easy to deal with. Use a pressure gauge to check the pressure, if it is not enough, just add it.

2. The voltage of the power supply is not enough.

Solution: Maintain a normal supply voltage.

The power supply voltage is unstable, and it often fails to reach the normal voltage, especially during the peak of electricity consumption. The manifestation of this problem is: when the voltage is normal, the air conditioner is also normal, and when the voltage is unstable, it will affect the air conditioner when it is not cold.

If the air conditioner is not cooled, first check whether it is caused by the wrong setting adjustment.

The second is to check whether the cleaning air conditioner is too dirty, causing obstruction normally, or if the fan speed is too slow, affecting the temperature exchange.

Otherwise, you have to contact after-sales service or ask professionals for maintenance.

The reasons why Midea's air conditioner does not refrigerate are:

1.Air conditioner air compressor failure.

2.The air conditioning door is not closed tightly.

3.The reduction dose of the air conditioner is not or is severely lacking.

4.Turn on the air conditioner often and can't cool down in time.

These are the reasons why Midea's air conditioner is not cooling, you can try to check the reasons slowly.

How to adjust the Midea air conditioner if it is not cooled?

Due to the long service life, the refrigerant inside is insufficient, resulting in even if the internal and external units are running normally, the house is still hot into a "dog", and you can't feel a trace of coolness, but this is relatively easy to solve, just add some new refrigerant.

Why is the air conditioner not cold?

1. The compressor capacitor is in poor contact or damaged, resulting in the compressor not working normally.

2. If the remote control is in poor contact (for example, the battery of the remote control is insufficient and needs to be replaced, etc.) or the receiver of the air conditioner is poor, then the air conditioner will be turned on but not running normally, or sometimes working and sometimes striking.

3. If the control panel of the internal or external unit of the air conditioner fails, there will be a phenomenon that the air conditioner is turned on but does not move or you obviously let it go up and down, but it will give you a left and right movement, which is really a headache.

4. Once the resistance value of the indoor temperature sensing head changes, the outdoor unit of the air conditioner will not work normally, so the air conditioner will not refrigerate normally.

5. There is also a kind of failure that will occur in a few air conditioners, that is, the power supply of the air conditioner is reversed, but this generally occurs when the machine is installed, and the probability is very small, so you can rest assured.

Okay, how to adjust the air conditioner above for not cooling? The knowledge of the reasons why the air conditioner is not cold has been analyzed, just like the above question, the phenomenon of not cooling often appears, and there are many reasons, so it is necessary to check before use, determine the cause and then solve it, so as to spend the summer safely.

1. The freon in the air conditioner is not enough, which generally occurs in the air conditioner that has been used for more than one year. The freon function in the air conditioner is refrigeration, and if the air conditioner is used for a long time, the air conditioner will lack fluorine, and the external manifestations are not refrigeration, water leakage, shutdown, etc.

2. The air conditioner receiver is bad or the battery in the air conditioner remote control is dead, but you don't find it, then you turn it on, but it strikes, or sometimes it is refrigerated and sometimes it is not refrigerated.

3. When the voltage at home is unstable, it will directly affect the work of the air conditioner.

4. There is a dust filter in the air conditioner, which is to prevent the entry of dust and protect the air conditioner. Some customers have used the air conditioner for a long time, but they don't know how to clean it and maintain it, resulting in excessive dust accumulation, affecting the heat dissipation of the air conditioner, and it is difficult to refrigerate.

5. It's obviously turned on, but it doesn't move, or you let it wind left and right, but it goes up and down. This phenomenon is generally caused by the failure of the control panel of the internal and external units of the air conditioner.

1. Check whether it is the lack of freon, and if so, add a little freon to the air conditioner immediately. However, supplementing Freon requires professional staff, so remind everyone not to do it yourself.

2. Check whether the voltage at home is stable and whether the remote control of the air conditioner has electricity, and replace the battery with a new one if there is no power. If the voltage is not stable, we have to buy a voltage regulator to stabilize the voltage.

3. Regularly clean the indoor and outdoor units of the air conditioner. It is recommended that you buy a bottle of detergent specially designed to clean the filter, which can quickly dissolve the dust on it, rinse it and dry it.

Reasons why Midea's air conditioner is not cooling:

Midea air-conditioned city-wide repair office.

Adjust the room temperature carefully. When cooling, the room temperature is increased by 1 degree Celsius, and when heating, the room temperature is lowered by 2 degrees Celsius, which can save more than 10% of electricity. When the air conditioner is used, the temperature is set at 26 28 in summer and 16 18 in winter.

Clean the filter regularly. Dust will clog the filter mesh and reduce the effect of heating and cooling, so it should be cleaned once every half a month.

When the air conditioner is not in use, the power supply should be cut off.

There are many reasons why the air conditioner is not refrigerated: (1) fluorine leakage at the connecting pipe joint; (2) There is a leakage point in the connecting pipe; (3) The wiring is incorrect; (4), fuse burning; (5) The compressor fails; (6) The external environment temperature is high, and the indoor personnel are more than the United States' air conditioners working at full load. (7) If the power supply voltage is too low, it is not easy to start the Midea air conditioner, and it will stop or the fuse will blow after starting, so it is recommended that the user install a power regulator.

8) The air outlet of the air outlet is not large if the temperature does not drop in the strong cold block room, which is the air filter has too much dust, clean the filter. (9) Improper adjustment of the thermostat. (10) Midea air conditioning installation location is not good, it will lead to uneven indoor temperature or poor refrigeration effect, if the above can not be determined, please call Midea's after-sales service **4008899315 let it deal with it!

If you still have questions, you are welcome to ask questions to the company in the United States; I wish you a smooth work and a happy life!

Air conditioning is an indispensable part of modern life, air conditioning provides people with coolness, but at the same time, air conditioning is always on is also easy to cause diseases, such as "air conditioning disease", etc., need to be used with caution.

Air conditioner not cooling reasons:

1. There is no refrigerant for the compressor, add refrigerant.

3. If the refrigeration system line is faulty, check the line.

4. The thermostat is broken, replace the thermostat.

5. The temperature sensor is broken, replace the sensor.

Check whether the ambient temperature of the external unit is too high. China's air conditioner generally adopts the T1 working condition in the temperate climate environment, and the applicable ambient temperature is between -7 and -43, when the environment is out of range (such as the outdoor ground temperature can reach 60 when the high temperature in summer), the external radiator can not effectively dissipate heat, which will cause the air conditioner not to refrigerate. In addition to hot weather, this situation also often occurs when the outdoor unit is installed in an enclosed space, and the heat emitted by the outdoor unit accumulates in the enclosed space, resulting in too high a temperature in the space, which in turn causes the radiator to be unable to effectively dissipate heat.

If the air conditioner can be cooled normally when the temperature is low in the morning, but not when the temperature is high, it is likely that this is the reason, and you need to find a way to reduce the temperature of the external unit without adding fluoride.

Possible causes.

1. The biggest possibility is that the freon of the air conditioner is not enough, if your air conditioner has been used for three years or more, the refrigeration effect is reduced or not refrigerated. You just need to ask the after-sales maintenance personnel to add a little bit to it. In addition, it is not excluded that improper installation can cause freon leakage and problems with the machine itself;

2. There is also a possibility that the power supply voltage is not enough, because the normal starting voltage of the air conditioner is 220V+-10%. Generally, in China's power supply system, almost all compressors above 200V can be started. When it is above 180V, there are 70-80 that can be started, and when it is above 160V, only a few can be started, if the power supply voltage is too low, it will affect the normal operation of the air conditioning product;

3. The power of the air conditioner is not enough, if your indoor space is relatively large, the refrigeration speed of the air conditioner will be relatively slow, you need to pay attention to the choice of air conditioner, 150-250w square meters when refrigerating, 250-350w square meters when heating, in addition, it is also necessary to comprehensively consider factors such as space height, level orientation, sealing performance and residential population;

4. If the air conditioner is not cleaned and maintained for a long time, the effect of the radiator will be affected due to dust accumulation and other reasons, resulting in the reduction of the cooling effect of the air conditioner. If the indoor unit is not cleaned for a long time, it will also be related to the health of the human body, and if it is not cleaned for a long time, bacteria will breed and pollute the air.

Generally speaking, there are the following reasons why Midea air conditioners do not refrigerate: First, there are loopholes in the compressor circulation system and light leakage of internal coolant. Second, the power supply system used by the compressor circulation system was cut off, causing the circulation compression system to stop working. Third, the compressor is damaged.

If the air conditioner is used for a long time, first check whether the compressor lacks freon or the starting capacitance capacity of the outdoor unit is reduced and cannot be started normally, and there is no refrigeration, of course, it is also possible that the filter screen of the indoor unit is dirty and the refrigeration effect is not good.

The most common is the lack of refrigerant in the system, and the insufficient working pressure of the system leads to poor refrigeration effect and no refrigeration. The internal filter screen is seriously dirty, the outdoor unit has poor heat dissipation, and the compressor starting capacitor is broken, resulting in the compressor being unable to start and run normally, resulting in no refrigeration. The second is that the control failure of the motherboard causes the air conditioner to not work normally, affecting the refrigeration.

The reasons why the air conditioner does not refrigerate are divided into three parts, first, the compressor is damaged! Second, the control board is damaged! Third, lack of refrigerant! Not refrigeration, nothing more than these three reasons.

There may be reasons why it is not refrigerated

1: The capacitor of the compressor burns out, 2: The refrigerant leaks.

3: The compressor is damaged.

4: The motherboard is damaged, resulting in no 220V output, and the mode switching fails 5: The dust accumulation of the indoor unit and the outdoor unit is serious, and the filter needs to be cleaned.

When looking for the reason for not refrigerating, first check whether the compressor is started.

If the air conditioner does not refrigerate, it may be that there is a lack of refrigerant, and you need to find the leakage point and refill the refrigerant, and there is also a possibility that the capacitance of the air conditioner is broken, and you can replace one.

Normally, it is a line problem, or it may be a compressor damage, so according to the situation, it is to look at the speculative damage or the line damage, and judge it yourself.

It could be that the air conditioner has not been cleaned for a long time. It is also possible that the voltage is too low.

It is also possible that the ice species is gone.

If the pattern is not wrong, the lack of refrigeration may be a leak of refrigerant.

There are only two common reasons for not refrigerating. The first reason is the lack of freon refrigerant, so the air conditioner does not cool. The second reason is that the compressor is faulty, and if it does not work, it will also cause the air conditioner to not refrigerate.

What exactly is the reason why the air conditioner is not cooling?

Air conditioning is an indispensable part of modern life, air conditioning provides people with coolness, but at the same time, air conditioning is always on is also easy to cause diseases, such as "air conditioning disease", etc., need to be used with caution.

First, it may be that the refrigerant leakage is insufficient (commonly known as "refrigerant" is not enough), and the refrigerant can be added.

Second, the power supply voltage is not enough, and the compressor cannot operate normally. It is recommended to install a voltage regulator.

3. The refrigeration power of air conditioning is small and the room area is too large; Room insulation is not effective. Take these factors into account when choosing an air conditioner.

Fourth, the external ambient temperature is too high, and the refrigeration time is longer than usual.

5. The air conditioner is not cleaned and maintained for a long time. Wash in a timely manner.

6. The copper pipe connecting the indoor unit and the outdoor unit is too long. Find a professional for commissioning.

For details, please call us or make an appointment for maintenance.

Check whether there is no freon, as long as the host is not broken, call the master who repairs the air conditioner to see if you want to flush freon, if there is no freon, flush freon to refrigerate.

I wish you happiness and joy, dear, please adopt, thank you.

Clean the external unit, it may be that the heat dissipation is not good, come down and check the starting capacitance of the compressor, and replace it if it is bad.

Just put a basin of water in the house.

Lack of refrigerant.

Find a master to pour it.

If you have been using it for many years, you should go to a master to add fluoride.
