The air conditioner at home can t be cooled, do any friends know what s going on?

Some time ago, the air conditioner in the couple's house was broken, and the people from Tianjin Longtai Company came to see, they said that the condenser was broken, and it was good to replace the condenser on the spot, and now the air conditioner is in normal use.

There are many reasons why the air conditioner does not refrigerate: please explain your problem in detail:

If: the internal machine starts, the external machine does not start, the machine stops after starting, and the cold air blows for a while, there is no more, etc.

There are many reasons for not cooling, and you haven't made the situation clear:

1: Fluorine is not enough. This is the most common problem and will be detected first after the door.

2: There may be a problem with the temperature you set. For example, if the outside temperature is 27 degrees and your air conditioner is set to 27 degrees, it will definitely have no effect, unless you are standing under the air conditioner and blowing it.

It's autumn, the room temperature is already low, and then the temperature you set is high, do you think he can run it cooling.

There are many reasons, first of all, we must determine whether to adjust to the refrigeration mode, in addition, to determine whether the refrigerant is not sufficient, whether the outdoor compressor is running normally, the indoor unit is generally set between 18-22 degrees, to ensure that the filter screen is clean, the external unit can be cleaned with water, the external unit is generally not afraid of water, or directly find after-sales.

It may be that there is no freon, and you can let the after-sales rush freon.

What does the fault look like?

A rice cooker is new.

For modern people, air conditioning is like a banana fan in summer, which can save living beings from the mountain of flames. However, on a hot summer day, I suddenly found that the air conditioner in my home was not cold. It's too spicy to be too hot for friends to stand it.

What exactly is the reason why the air conditioner is not cold? What should I do?

1. The service life of the air conditioner has arrived. After the normal service life, the air conditioner is aging. The life of large household appliances such as air conditioners is generally 15 to 20 years (the specific service life can be seen in the product manual).

After this age, the air conditioner does not turn on the air conditioning, so this is generally the reason. Solution: Replace the air conditioner with a new one.

2. The refrigerant is not enough. In other words, the types of snow we usually talk about are not enough. The air conditioner was on because of Freon.

As soon as the air conditioner is activated, the freon transport function will be turned on. Freon deficiency is the general cause. Air conditioner in normal condition after 3 4 years of use.

If the air conditioner is not as good as it used to be, there are many reasons for this. Solution: Ask an air-conditioner maintenance technician to add the type of snow.

3. Some air conditioners need to be installed or are unreasonable, the ventilation pipe is too long, and the heat transfer efficiency is low, resulting in the air conditioner not being refrigerated. Solution: Shorten the length of the copper pipes of the outdoor unit and indoor unit of the air conditioner as much as possible.

4. The air conditioner has not been cleaned for a long time, so do not freeze it. Through long-term use, the outdoor unit absorbs a lot of dirty things such as dust and garbage on the radiator, resulting in poor heat dissipation effect of the radiator and not freezing. Solution: Clean the air conditioner for maintenance.

5. The external environment temperature is too high, and the air conditioner is not refrigerated. In high-temperature areas, the outdoor temperature is too high and exceeds the limit of the air conditioner's refrigeration, which may also cause the air conditioner to not refrigerate. This kind of non-freezing situation is often higher than the space where the equipment of our outdoor unit is blocked and the temperature around the outdoor unit.

Solution: Change the installation position of the outdoor unit, ventilate as much as possible, and install it in a shading place.

6. The filter in the air conditioner has accumulated too much dust, and the air outlet is not normal and the air outlet is not frozen. Check the machine in the air conditioner, and after the machine in the air conditioner is working properly, check the filter of the internal unit. If there is a lot of dust in the filter.

Solution: Please use a special filter to spray out the detergent before cleaning.

7. The household voltage is insufficient, the power supply voltage is abnormal, and the power supply voltage is low. When the voltage is insufficient or the electricity is not normal, the air conditioner will stop suddenly and the air conditioner may not work. The cold air from the air conditioner was hot and cold.

In this case, it should be assumed to be due to voltage instability. Solution: Ensure the stability of the voltage at home.

Especially during peak power hours, I bought a high resistance and voltmeter to monitor the voltage condition.

The reason may be that the refrigerant is insufficient, and the exhaust outlet is blocked by not being cleaned in place, so the air conditioner should be cleaned regularly and refrigerant should be added regularly.

1. The indoor unit or outdoor unit is not running.

Check whether the air conditioner is running 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, 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.

It may be that there is a lack of freon, you can find an air conditioner to check, if it is indeed because of the lack of freon caused by the lack of refrigeration, one or two hundred yuan can solve this problem.

Because the air conditioner may need to be cleaned, there is too much dust on the radiator, it is recommended to find a master to clean the air conditioner.

Because the air conditioner is broken, you should let a professional master check it for yourself to see if there is something wrong with it and how to repair it.

It may be that there is a lack of some refrigerant fluid, so that a good effect cannot be achieved, and many times this is the problem.

You know, it may be because the circuit inside is loose, or it may be because the circuit inside is burned out, so there is no way to refrigerate.

It is very likely that the freon is not enough, it may be because the voltage is not enough, it may be because the power is not enough, it may also be because the outside temperature is relatively high, or it may be because the air conditioner has not been washed for a long time.

Introduction: If you see that the air conditioner in your home suddenly stops cooling, be sure to find the reason.

If you see that the air conditioner in your home suddenly does not refrigerate, you should take a look at what is wrong with the air conditioner at this time, and you must solve it in time. Some people always overuse the air conditioner when they use it, which will put a lot of burden on the air conditioner. When using the air conditioner, you must see it clearly to see if the air conditioner should be cleaned in time.

If there are often some problems with the air conditioner, then it is necessary to repair it in time to prevent the air conditioner from happening in this situation. Some air conditioners are not cooling, and they have to see if there is a problem with the remote control board and need to adjust it. If there is a lot of dust on the air conditioner, you should wipe the air conditioner in time, so that the air conditioner can be used better and there will be no refrigeration.

Many people like to use air conditioners, so you have to take a look, if there is frost on the outside of the air conditioner, you should also defrost it in time.

There are many people who have a lot of problems after using the air conditioner, and you have to learn to change at this time. Some air conditioners will have many cases, if the cooling effect of the air conditioner is not the same as before, then be sure to find the reason. If you don't know how to deal with the air conditioner, you must clean it up in time, don't let some situations appear on the air conditioner, if there is a lot of dust on the air conditioner, then the wind blowing out will become unheated.

If the air conditioner is not cooled, first of all, you must find some professional people to repair it and help you repair the air conditioner. Some people want to do it when they see that the air conditioner is broken, at this time you have to cut off all the power supply, there is no power supply, and then deal with it. Many people don't know why the air conditioner has this situation, so if the air conditioner is not as effective as before, it may also be because it has been used for a long time.

It may be that the desired temperature is not adjusted, it may be that there is too little freon in the air conditioner, it may be that the voltage is unstable, the air conditioner has not been cleaned for a long time, and the number of air conditioners is not enough.

Because the voltage of the air conditioner is not enough, or there is a problem with the power, or it may be a lack of fluorine, you should immediately check some lines, or you can call some warranty personnel.

This is because the refrigerant is gone, and it must be replaced at this time, and it can be repaired by a professional.

The reasons for the sudden stop of the air conditioner are: damaged capacitors, timer mode, sleep mode, lack of freon, and temperature conditions that do not match.

1. The starting capacitor of the cooling fan of the outdoor unit is damaged, the fan does not rotate, and the temperature is too high and the protection stops. It can be seen with the naked eye. If the starting capacitor is damaged, replace the fan starting capacitor.

2. If the air conditioner turns on the timing mode, the air conditioner will automatically shut down when the time reaches the predetermined time point, which is a normal phenomenon, and it is enough to restart the air conditioner.

3. If the air conditioner is in sleep mode, the remote control will automatically turn off when the temperature reaches the adjusted temperature. You can view the remote control, turn off the sleep mode, and change the mode to the normal mode of the sock return.

4. If the freon in the air conditioner is insufficient, it will also cause the air conditioner to fail to refrigerate, and the internal temperature of the air conditioner is too high, and the air conditioner will start the self-protection function and shut down. Say goodbye.

5. In order to make the indoor temperature conditions more suitable, many users set the temperature of the air conditioner in combination with the needs of the environment, and when the air conditioner reaches the set temperature standard, the air conditioner will stop supplying air, so the air conditioner will shut down.

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.

1: The service life of the air conditioner has expired, the service life has expired, and the air conditioner is aging.

I bought a second-hand air conditioner before, and suddenly it was not refrigerated some time ago, in order to find the reason why the air conditioner is not cooling, I read a lot of books and found a lot of information on the Internet, although I have enriched myself with some knowledge about the air conditioner is not cooling, but I am still helpless, the reason is that the service life of large household appliances such as air conditioners is generally between 15 and 20 years, and even if it is repaired after this year, the same problem will occur again. Solution: Hurry up and change to a new one!

Two: the refrigerant is not enough, that is, the freon is not enough.

The reason why the air conditioner is refrigerated is because of Freon, when the air conditioning motor is started, it will turn on the delivery function of Freon, the general reason is that the air conditioner is used for three or four years, and the normal situation is that if you find that the air conditioning refrigeration effect in your home is not as good as before, most of the reason is this. Solution: You can add freon yourself, if not, it's best to find a maintenance master to help you.

3. The copper pipe between the outdoor unit and the indoor unit is too long.

Some friends feel that the outdoor unit is too noisy, so they deliberately move the outdoor unit far away, which increases the transmission distance, resulting in the reduction of the cooling effect of the air conditioner. In addition, it also increases the cost of installation, which is not cost-effective. The air conditioner is too long due to the demand of the device or the unreasonable installation, so that the heat transfer efficiency is low, and the air conditioner is not cooled.

Solution: Try to shorten the length of the copper pipe between the outdoor unit and the indoor unit of the air conditioner.

Four: the household voltage is not enough, the power supply voltage is abnormal, sometimes high and sometimes low.

In some large factories or companies, air conditioning is generally used for refrigeration, and then refrigeration in different areas is realized through ventilation fans, where there will be problems when the voltage is insufficient, the air conditioner will suddenly stop, and it will not be refrigerated at all; Or the cold air of the air conditioner is hot and cold. Many friends can't find out the reason for this kind of non-refrigeration, and the maintenance master also dismantles and installs the air conditioner, but it still doesn't work. This situation should be considered to be caused by voltage instability.

Solution: Ensure that the voltage at home is stable, especially during the peak period of electricity consumption, buy a higher resistor and voltmeter to monitor the voltage situation at all times.

Five: The power of the air conditioner is not enough to not refrigerate.

Some friends in order to save money to buy a small number of air conditioners in a very large room, the small number of air conditioning power is not enough, and some although the air conditioning power and the room area seems to match, but because the room is relatively not closed, or there is a heat source in the room (there are many computers), of course, the glass room is also one of the heat sources, and so on. This kind of situation is easy to ignore in our daily life, and if we can find this as the cause and deal with it well, it can not only make the air conditioner cooler, but also save electricity, and also prolong the service life of the air conditioner. Workaround:

When buying an air conditioner, estimate the practical area, and if you have enough funds, you can add more horses on the basis of the appropriate number of horses.

What is the reason why Gree air conditioner does not refrigerate.

1. Air conditioning power supply problem.

There are many reasons why the air conditioner is not cooling, and we are checking why the air conditioner is not cooling. First of all, you need to check whether the power supply of the air conditioner is plugged in, whether the connection between the connector of the air conditioner and the power supply is not working, if the air conditioner is not connected to the power supply, of course, there will be no refrigeration.

Maintenance method: If there is a problem with the power supply of the air conditioner, you only need to plug the power supply of the air conditioner back in to ensure that the air conditioner can be energized normally.

2. The voltage of the air conditioner is unstable.

After we check the power supply of the air conditioner, we will see if the voltage of the air conditioner is unstable or insufficient. The voltage of the air conditioner is unstable and cannot reach the predetermined voltage of the air conditioner, just like people work without food, the air conditioner will work very hard, and the voltage will be unstable during the peak period of electricity consumption.

Maintenance method: At this time, the situation that the air conditioner is not refrigerated is not a situation that we can solve with a method, we need to start from the aspect of stabilizing the air conditioning voltage.

3. The refrigerant is not enough.

The reason why the air conditioner does not refrigerate is sometimes similar to the reason why the refrigerator does not refrigerate, all because the refrigerant is not enough, resulting in the air conditioner or refrigerator not cooling. Generally, the air conditioner has been used for a long time, the refrigeration effect of the air conditioner will become worse, and the refrigerant of the air conditioner will gradually volatilize with the change of time.

Maintenance method: The refrigerant of the air conditioner is not enough, as long as enough refrigerant is added for the air conditioner, the problem of the air conditioner not being refrigerated can be solved. However, if the refrigerant of the air conditioner is not enough because of the leakage of the refrigerant, we need to seal the cavity of the leaking part of the air conditioner by welding and repairing, and then add enough refrigerant to solve the problem.
