What should I do if the air conditioner doesn t turn off for a few days in a row, and then suddenly

1. One of the reasons why the air conditioner is not refrigerated: Freon is not enough (commonly known as not enough refrigerant) Solution: Supplementing Freon can solve the problem of air conditioning not refrigerating.

2. The second reason why the air conditioner does not refrigerate: The voltage of the power supply is not enough Solution: Maintain the normal power supply voltage.

3. The third reason why the air conditioner does not refrigerate: The power of the air conditioner is not enough to not refrigerate the solution: The power of the air conditioner and the refrigeration capacity required by the space want to match.

4. The fourth reason why the air conditioner is not refrigerated: The external environment temperature is too high and the air conditioner is not refrigeratedSolution: Change the use environment of the outdoor unit (move away from the high temperature environment or make the surrounding air of the outdoor unit easier to circulate).

5. The fifth reason why the air conditioner is not refrigerated: The air conditioner is not cleaned and maintained for a long timeSolution: Clean and maintain the air conditioner, so that the clean outdoor unit can be more tolerant of late heat dissipation.

6. The sixth reason why the air conditioner is not refrigerated: the copper pipe between the outdoor unit and the indoor unit is too long Solution: Try to reduce the length of the copper pipe between the outdoor unit and the indoor unit of the air conditioner.

Possible reasons why the air conditioner suddenly does not cool:

1. The air conditioner is broken.

2. The air conditioner caused by power failure is not refrigerated.

3. The air conditioner automatically identifies and stops running by the thermostat.

The air conditioner is equipped with a "thermostat" that controls the indoor temperature according to the set temperature when the air conditioner is turned on. Set 27 degrees Celsius, the air conditioner has been running for a long time, and when the indoor temperature reaches 27 degrees Celsius, the air conditioner will start to rest (stop); After stopping for a while, when the indoor temperature slowly rises to 27 degrees Celsius, this "thermostat" will command the air conditioner to start working. This is how the air conditioner keeps running, stopping, running, and shutting down again to maintain the required indoor temperature.

If the air conditioner starts normally, but the cold air does not emit air, it is likely that the filter is too dusty, and it is best to spray it with that special filter cleaner. Just clean the filter.

It may also be the so-called lack of fluorine, that is, the so-called freon, if it is insufficient, it is necessary to add freon, and at the same time check whether there is a leakage in the cold circulation system.

If there is no above problem, the air conditioner can also operate normally, then check the operation of the air conditioner fan, if the air volume of the fan is very small, then it may be that the fan motor is old, and the fan motor should be replaced with a new one.

Air conditioning is not refrigerated for a long time, you should find professional personnel to solve, air conditioning in the process of use should also be maintained and cleaned frequently, can not be used for a long time, air conditioning also needs to rest, when choosing air conditioning, it is also necessary to pay attention to the quality of the problem.

The air conditioner does not refrigerate and turns off automatically, indicating that the air conditioner is broken.

We take a certain force air conditioner here as an example, the air conditioner is not refrigerated, and it can be refrigerated after restarting, which may be due to a problem with the compressor capacitor, or it may be a compressor failure, or it is caused by the aging of the compressor, resulting in a decrease in efficacy that is not enough to support, and the relevant person should be contacted in time for repair or replacement.

There are two reasons why an air conditioner is not cooling:

The first is external reasons, because the room is too large and the air conditioning horsepower is insufficient, resulting in no air conditioning refrigeration, or the air conditioning installation is unreasonable, such as the refrigeration effect is not obvious due to the long ventilation pipe.

The second is the air conditioner itself, due to the problem of the compressor, the use time is too long, resulting in the aging of the compressor, such problems need to find professionals for maintenance; It may also be that there is a shortage of freon, which is commonly known as refrigerant and refrigerant, resulting in low refrigeration efficiency, poor effect or no refrigeration, which can be solved by timely supplementation of freon. It should be noted that this answer is applicable to most brands of air conditioning models such as Gree, Midea, and Haier.

The air conditioner suddenly stopped cooling, and then turned it off for half an hour and then turned it on again, because 1, the vacuum degree of the system is not enough, and the refrigerant is mixed with moisture! It is easy to form ice plugs at the capillaries, which affects the circulation of refrigerant! 2. It is the problem of flow path welding, there may be micro plugging or half plugging, and it is easy to freeze at the position of the welding plug, which affects the refrigeration effect!

The first problem is relatively easy to solve, put off the refrigerant, drain the vacuum and recharge the refrigerant, the second may be relatively difficult to deal with, and it needs to be checked out** blocked, and it can be solved with a welding torch! However, at present, it is not refrigerated for a period of time, and it can still be refrigerated after stopping for 10 minutes and waiting for the ice to melt. Comment oo chengguan captain oo installed hardware digital products mobile phone digital may be the temperature sensor is broken, very small, very cheap, mine is.

In the summer, after driving for an hour, it is not refrigerated, and it is good to stop for ten minutes, and it is really annoying to drive long distances. After the air conditioner is broken, it can't sense the temperature, and it keeps on until it freezes. The solution is as follows, check whether the connecting pipe is broken, the fracture will cause refrigeration leakage, the solution is to weld, and refill the refrigerant.

If the capillary or filter drier is clogged after inspection, you can replace the capillary tube or filter drier of the same specification, and you can do it after replacement.

Check the results, if there is a mechanical failure of the reversing valve itself, such as the spool jam or leakage, the reversing valve should be replaced.

If too much dust is found in the air filtration area, the airflow path will be blocked and the air volume will be reduced, so the air filter should be cleaned.

If the fan blades are found to be loose and cannot rotate at the same time as the motor, the problem can be solved by simply tightening the fan shaft.

If the ventilation of the condenser is blocked, the dust on the surface of the condenser should be removed, and finally the air inlet and outlet of the condenser should be dredged to solve the problem.

1) The power supply voltage is too low, which causes the air conditioner to not be easy to start, stop after starting, or blow the fuse. This is not a fault, as long as the cause of power supply is checked, it is the power grid voltage is too low, the user should install a power regulator to make the voltage reach 220V, so that the air conditioner can be used normally.

2) When the room temperature cannot be lowered in the strong cold block, the air outlet is not large, which is the air filter with more dust accumulation, which blocks the air circulation, so that the refrigeration capacity in the machine cannot be brought out by the flowing air in time, resulting in insufficient refrigeration capacity. This is not a fault, as long as the filter is removed and cleaned, it will be back to normal.

3) The thermostat is not properly adjusted, and the maximum function of refrigeration is not played, resulting in the room not being able to cool down, which can be solved after adjusting the thermostat.

In this case, it is estimated that the machine is too dirty to obstruct ventilation or the fan speed is too slow, which affects the temperature exchange, resulting in abnormal system pipeline pressure and compressor thermal protection shutdown.

As a user, the inside of the air conditioner should be thoroughly cleaned, and then powered on to test the machine after cleaning the filter to see how it is, to see if the fan speed is normal, and whether the external unit is directly exposed to the sun, which will affect the ventilation and heat dissipation, and will also lead to the shutdown of the compressor thermal protection.

The air conditioner does not refrigerate after half an hour, and the reasons for this failure are as follows: 1. The air conditioner has poor heat dissipation, the external fan speed is slow or the air conditioner is dirty. 2. The compressor is broken.

3. The compressor overheating protector is broken. 4. The temperature sensor is broken. 5. Lack of refrigerant, resulting in poor refrigeration effect.

Because the weather is hot now, the use of the air conditioner for a long time, maybe there are some failures after the air conditioner is heated, and it is not refrigerated, and then it is turned off for half an hour to rest for half an hour, and then it returns to normal.

There are several reasons why the air conditioner only emits air and does not refrigerate:

1. The controller does not set the refrigeration state or the set temperature is too high;

2. The power supply voltage of the air conditioner host is not enough to cause the host to fail to start;

3. If the refrigerant of the air-conditioning host is not connected to the bell during installation, resulting in light leakage, or the copper pipe pipeline is not connected well or the copper pipe is broken, of course, it is not excluded that the copper pipe of the host itself is broken, such as: the evaporator, the condenser or the pipeline connection of the unit itself;

Fourth, the compressor of the main engine of the air conditioner is burned out.

Solution: Call a professional air-conditioning maintenance personnel.

1. Reason: The temperature difference between the air supply and return air (indoor temperature) of the air conditioner under normal operation should be more than 8, if it cannot be reached, it means that the refrigeration capacity of the air conditioner is not enough, and the cause should be identified. The common causes may be:

1) The refrigeration load is overloaded or the room is too large.

2) The installation site is inappropriate, the airflow circulation is not sufficient, etc.

2. Solution:

1) First of all, find out whether it is caused by the overload of the air conditioner refrigeration load of the air conditioner, and try to reduce the refrigeration load or increase the cooling capacity of the air conditioner.

2) Then look at whether the air conditioner of the air conditioner is properly installed, if it is not suitable, the cold air will not blow around the person, so that the person does not feel cold. When the airflow circulation of the air conditioner is not smooth, such as the evaporator has a lot of ash, the gap between the fins is blocked, or the air filter is blocked by dust, the circulating air is reduced, and the cooling capacity of the air conditioner of the air conditioner can not be fully utilized.

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 running, 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 early indoor and 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, the use area of an air conditioner per mu is less than 10 square meters, and the house of 10-18 square meters should choose the 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.

The common reasons why an air conditioner doesn't cool down when it's on are as follows:

Reason 1: Insufficient freon (commonly known as fluoride deficiency).

Most of the reasons for this non-refrigeration are the air conditioners that have been used blindly and brightly for three or four years, and most of them are also a normal phenomenon, which belongs to the normal consumption of air conditioning refrigerant (that is, the freon or refrigerant we often say) after long-term use, but this is only manifested as insufficient refrigeration compared with the previous normal situation, and will not be completely uncooled, because the pressure is not enough, and it will not be too far from the normal value. 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.

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

I have encountered such a user, at home always said that the air conditioner is not cool enough, to check and found that it is normal, checked several times and found no problem. Later, an inspection finally found that the power supply voltage there was unstable, and often could not reach the normal voltage, especially during the peak of electricity consumption, it was more likely to appear this kind of grinding wide image. The manifestations of this kind of question and question are:

When the voltage is normal, the air conditioner is also normal, and when the voltage is unstable, it will affect the air conditioner sometimes not to cool (the internal unit works, the compressor does not work). We have to start with the supply of a stable voltage to solve the problem.

1. It may be because the refrigerant is insufficient, that is, freon, commonly known as "refrigerant". 2. It may be that the filter of the air conditioner has too much dust, which causes the problem. 3. It may be that the ventilation pipe of the air conditioner is installed for a long time, which will lead to poor effect of transferring indoor heat to the outdoors.

Suggested treatment: 1. Check whether the refrigerant is not enough, if it is insufficient, you should add freon, you can find a professional air conditioning maintenance department to deal with it. 2. If the air conditioner is turned on for a while, it will not be refrigerated, or it may be due to too much dust on the filter, so you can disassemble and clean it yourself or use a special filter cleaning agent to spray it to clean the land.

3. If the air conditioner is exposed to the outdoors for a long time, it will be easy to absorb dust and some sundries, and if it is not treated, it will affect the heat dissipation performance of the machine and cause the refrigeration effect of the air conditioner to deteriorate. The indoor unit is related to health, if it is not cleaned for a long time, it will breed a lot of bacteria, pollute the air, and it is recommended to find after-sales personnel to clean up the internal and external units of the air conditioner regularly every year. 4. If the ventilation pipe of the air conditioner is installed for a long time, it will cause the air conditioner to not refrigerate for a while, at this time, it is best to contact the installer to reinstall it to the best position, and try to make the air conditioning ventilation pipe as short as possible.
