After the air conditioner is repaired, it doesn t cool down for a few minutes?

1. Open the panel of the indoor unit half an hour after the air conditioner is turned on, and the evaporator should be covered with condensate. And note: when running, the light will be on and off, but it is also fluorine.

2. Use a thermometer to measure the temperature difference of the air inlet and outlet of the indoor unit, the difference is normal if the difference is more than 10 degrees, and the difference of the air conditioner with good effect can reach about 15 degrees, if the temperature is too small, it is a lack of fluorine.

3. In the place where the outdoor machine can be touched, after 15 minutes of starting, touch the two valves of the external machine, there should be a large temperature difference, the frosting of the thin tube indicates the lack of fluorine, and the frosting of the thick tube is the poor circulation of the system.

If the air conditioner is not deficient in fluoride through these 3 tricks, then why is there no refrigeration? Its practical use of these few tricks can be easily solved!

1. The air conditioner is not cleaned and maintained for a long time, and after a long time of idle and using the filter, wind blades, and wind wheels of the internal unit, a lot of dust and other stolen goods are adsorbed, resulting in a very low temperature of the indoor unit air outlet, but the air blowing is not far away, and the room circulation slows down. As long as regular cleaning and maintenance, the state of uncooled air conditioning can be avoided.

2. If the outdoor temperature is too high, the condenser temperature of the air conditioner will exceed the condensation heat dissipation temperature, and the air conditioner will not work normally. You can first try to physically cool the outdoor unit, such as showering water and shading, so that the outdoor unit of the air conditioner is in a comfortable working environment. If the air conditioner is turned on at night, the air conditioner can operate normally, and the cooling effect is good, so there is no need to rush to repair.

3. Check whether the horsepower of the air conditioner matches the size of the room. The size of the air conditioner is determined by the number of horses, and the number of air conditioners has the most direct relationship with the usable area. The number of horses is small, the air conditioning is slow, and the number of horses is a waste of money.

Therefore, how big the room is to match the appropriate air conditioning.

The air conditioner is repaired for a few minutes and then it is broken, we must first understand what causes the air conditioner to always be broken, and then repair it according to the situation, so as to ensure that the air conditioner can be repaired and no longer broken.

1.The air conditioner was on and it wouldn't be cool after a while. In this case, the indoor and outdoor units are too dirty, resulting in overheating protection of the outdoor compressor.

As a result, the air conditioner can no longer continue to refrigerate, resulting in the phenomenon that the air conditioner does not refrigerate after it is turned on. 2.The reason why the air conditioner can be turned on for cooling after a while may also be that the outdoor fan is turning too slowly.

Clean the filter screen of the indoor unit first, and then clean the finned aluminum foil fins of the outdoor unit, which can be directly rinsed up and down with a water hose. 3.If the fan speed is too slow, it is most likely caused by poor motor lubrication, reduced starting ability, or short circuit between coils.

The failure phenomenon that the air conditioner can be turned on and does not refrigerate after a while is caused by the failure of the external air conditioner, which requires outdoor high-altitude work. It is recommended to find a local professional air conditioning maintenance department for on-site maintenance. When you first start turning on the air conditioner, you need to pay attention.

1.If the air duct of the air conditioner is installed for a long time, it may lead to poor heat transfer from the indoor to the outside, and the cooling is not obvious. Find a good location to reinstall and minimize ventilation ducts.

2.Cleanliness issues. Sometimes, not cleaning the air conditioner for a long time will also lead to a decrease in the cooling effect of the air conditioner, and the air conditioner also needs to be cleaned and maintained.

The outdoor unit of the air conditioner is exposed to the outdoors for a long time, which is easy to absorb dust and debris. If it is not cleaned for a long time, it will affect the heat dissipation performance of the machine and lead to the cooling effect of the air conditioner. 3.

Voltage and frequency problems: The reason why the air conditioner is not cooling may be that the air conditioner is not frequent enough. Generally, an air conditioner has a usable area of less than 10 square meters, and a house of 10-18 square meters should choose a matching air conditioner, and so on. The larger the area, the more often the air conditioner should be turned on.

Sometimes the outdoor temperature is too high, which will also cause the cooling effect of the air conditioner to decrease.

1. The power of the air conditioner is not enough: this is also one of the common reasons for not refrigerating, but there are many reasons for this lack of refrigeration, such as a small power air conditioning pipe in a large area of the room, and some although the power of the air conditioner and the room area seem to match, the freon is not enough (also known as "refrigerant" is not enough: this is a normal situation, generally appears in the use of three to four years of old air conditioning, the air conditioning is not completely not refrigerated, but the refrigeration effect is not good enough.

2. The old air conditioners all use freon as refrigerant, which will volatilize off after a long time of use, and it is not excluded that improper installation will cause freon leakage and the problem of the machine itself. The voltage of the power supply is insufficient: the power supply voltage is unstable and often cannot reach the normal voltage, especially during the peak of electricity consumption.

Of course, this kind of problem is obviously not something that a skilled air conditioner maintenance master can solve, and we must start from the aspect of providing a stable voltage to solve the problem.

3. However, due to the fact that the room is relatively unsealed (such as doors and windows are wide open, etc.) or there is a heat source in the room (such as many computers), of course, the glass room is also one of the heat sources.

What mode of air conditioning is refrigeration.

1. Enter the remote control interface of the air conditioner, the mobile phone is facing the air conditioner, click on the key point to turn on the air conditioner, what appears at the moment is the active form, you can click the form key to switch the form, the form is active, refrigeration, heating, ventilation and dehumidification. Click the form button to switch a form, when the screen shows that the refrigeration is, the air conditioner is the refrigeration form.

2. The remote control of the air conditioner adjusts the refrigeration form, press the key point of the air conditioner against the remote control to turn on the air conditioner, and then press the form key of the air conditioner remote control. There are five forms of active, refrigeration, dehumidification, heating and air supply, press the form button to switch a form, when the remote control shows refrigeration, the air conditioner is the refrigeration form.

The situation you mentioned should be that the refrigerant pressure is insufficient, that is to say, it may be a lack of freon, and you can find an air conditioner master to add some fluorine.

He just started refrigeration, and it won't be refrigerated after a while, it may be that there is a problem with the braking system inside, or the things inside should be cleaned up, if it is not cleaned, there is no way to achieve the effect of refrigeration, so this should be the need to clean up the inside of the air conditioner, so that the effect of cleaning can be achieved.

If the air conditioner is turned on for a while, cooled for a while, and does not refrigerate for a while, it means that there is still something wrong with its motor, or its program to control the temperature is not very accurate, so. Something malfunctioned.

The air conditioner just starts to cool down, and it doesn't cool after a while. This one must be broken, a part in the PC version.

One of the reasons why the air conditioner does not refrigerate: there is not enough freon (commonly known as "refrigerant" is not enough).

When the ambient temperature is about 35 degrees Celsius, 1, low pressure and high pressure 3, static pressure.

This is a normal situation, usually in the case of an old air conditioner that has been used for three to four years. The air conditioner did not completely stop cooling, but the effect of cooling decreased. This is because old air conditioners use freon as a refrigerant, which will volatilize after long-term use.

Therefore, users only need to add a little to the regular air conditioning maintenance point. In addition, it is not excluded that improper installation can cause freon leakage and problems with the machine itself.

The second reason why the air conditioner does not refrigerate: the power supply voltage is not enough.

The normal starting voltage of the air conditioner is 220V+-10%. In China's power supply system with a phase voltage of 220V and a line voltage of 380V, almost all compressors above 200V can be started. At 180V or more, 70-80 can be started, and at 160V or more, only a few can be started.

I've done it myself. Below 160V there is almost no possibility of starting. As a rule of thumb, the compressor starting voltage is more reliable above 190V.

The third reason why the air conditioner does not refrigerate: the power of the air conditioner is not enough.

The general selection principle is: 150-250W square meters for cooling and 250-350W square meters for heating, in addition to comprehensive consideration of factors such as space height, level orientation, sealing performance and residential population.

The fourth reason why the air conditioner does not refrigerate: the external ambient temperature is too high.

There is a common saying: when the outdoor unit is in an environment above 43°, most air conditioners are difficult to transfer the heat from the indoor to the outside, resulting in no refrigeration.

The fifth reason why the air conditioner is not refrigerated: the air conditioner is not cleaned and maintained for a long time.

If you want the air conditioner to operate normally and not affect human health, but also to prolong the life as much as possible, obviously, it is impossible to leave it alone as soon as you buy it and install it. 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, resulting in the reduction of the cooling effect of the air conditioner. The indoor unit is related to the health of the human body, and if it is not cleaned for a long time, it will breed bacteria, pollute the air, and make people sick.

The sixth reason why the air conditioner does not refrigerate: the copper pipe connecting the indoor unit and the outdoor unit is too long.

The maximum allowable length of the connecting pipe of the air conditioner shall not exceed 8 meters for one horse, 10 meters for the horse, and 15 meters for more than 2 horses. The height difference between indoor and outdoor units shall not exceed 5 meters.

First of all, check whether the air conditioner is operating normally, including the indoor unit and the outdoor unit, especially the compressor of the outdoor unit, as long as one of them is not running normally, then you have to ask the master to repair it. Then check the filter of the air conditioner, if the air conditioner starts normally, but it does not emit cold air, it is likely that the filter screen is too dusty, and it is best to spray it with that special filter cleaning agent.

Hello, the air conditioner has just started refrigeration, because the engine has just started, the water temperature has not reached the normal working temperature, the condenser fan heat of the air conditioner is better, when the coolant temperature rises to the standard temperature, the fan heating effect is weakened, resulting in poor air conditioning refrigeration effect.

Solution: Clean the appearance of the condenser.

Hello, this is mainly due to the absence of fluorine in the air conditioner. After asking the staff to help you add clothes, the air conditioner can be cooled normally. If the service is normal, it means that there is a problem with the cold drink tube and it needs to be replaced.

It should be the abnormal pressure of the air conditioner's system that causes the compressor to shut down for thermal protection. There are many reasons for this, such as the air conditioner is too dirty, obstructing ventilation, the fan speed is too slow, affecting the temperature exchange, the system piping is blocked, or the compressor itself is not performing well.

It is recommended to contact after-sales service or ask a professional for maintenance.

1.It is mostly caused by the unstable or too low power supply voltage, or the poor temperature exchange of the air conditioner leads to the thermal protection shutdown of the compressor, which causes the thermal protection shutdown of the compressor.

2.For example, the indoor unit filter is too dirty, the fan speed is too slow, the outdoor unit heat sink is too dirty or the fan speed is too slow, the main reasons for the slow fan speed are the decrease in capacitor capacity, poor lubrication of the motor bearing, short circuit between the turns of the motor coil, or the deformation or fracture of the fan blades.

The air conditioner just started to refrigerate, and after a while it will not be cooled, this problem should be to check the heat dissipation first, because if the heat dissipation is not good, the air conditioner board will be cut off and not work. The heat dissipation problem is solved, and I think your air conditioner will. It works great.

If the air conditioner starts to cool and does not cool after a while, it means that there is a certain problem with the motherboard inside and needs to be maintained.

If the empty meter just started, then the work in this case is to look at the thing, if there is nothing bad about this thing, then the car is not right, if the empty just started to eat, and then this is not right, then after a while can not, then it is likely that his breeding current is not enough, may have to change its capacitor.

Is there a shortage of refrigerant? If the refrigerant is lacking to a certain extent, the situation you are talking about will occur. It is best to ask a professional maintenance personnel to come to check and deal with it. By the way, check if there is a problem with the tubing.

There are quite a lot of reasons, first check whether the compressor of the external machine is running normally, it is best to focus on checking the system pressure, if the refrigerant is not enough, this situation will also occur!

The air conditioner just started to cool down, and after a while it won't be cold, what's going on? This is obviously fluorine leakage. The manufacture of air conditioning refrigeration relies on fluorine to refrigerate.

The air conditioner was indifferent at first, and after a while it was not cold, what was going on? I think it's possible that your temperature is not adjusted correctly, or the mode is adjusted incorrectly.

The air conditioner just started to cool and stopped cooling after a while, indicating that there was a problem with the compressor and a professional was asked to repair it.

It may be that the temperature has reached its set temperature, or it may be that the external unit has not started, causing it not to refrigerate.

I guess if the fan of the external unit is broken, so it won't be refrigerated.

There is a high chance of refrigerant leakage.

The air conditioner has just been turned on, and the skill has not lit up again, what is going on, it should be ready to break.

Homework lectures, can only be inaccurate for a while, from time to time air conditioning service what failure to use professional maintenance personnel to repair.

The air conditioner just started to refrigerate, and after a while it won't be cold, what's going on Does this need to add some vitality to it, the reason for this condenser You can find a professional master to give you a specific look.

After turning on the air conditioner, set the refrigeration and temperature, if the indoor temperature is higher than the set temperature, the air conditioner will start to refrigerate, when the set temperature is reached, the air conditioner will stop refrigeration, change to circulating air, and after the indoor temperature is higher than the set temperature, the air conditioner will restart to start refrigeration.
