The air conditioner is not refrigerated, the outside unit and the internal unit are blowing natural wind, the sound of the outside unit is small, and it is not hot, which often means that the compressor is not working, or the load is too light (the freon is missing, and the freon gas in the evaporator cannot be compressed into a liquid state), so the sound of the external unit is small and not hot.
You also talked about blowing a cold air every 2 or 3 hours for about 10 minutes It means that the freon is not all missing You can suppress the system first If you can stop it and charge it directly If you can't suppress it, then it may be more troublesome if the system leaks and you need to find a repairman to solve it Okay If you don't understand anything about this question, you can ask it, if you are satisfied, remember If there are other questions after this question Send another click to ask me for help, it is not easy to answer the question, please understand, thank you.

First of all, I said that the first two are wrong, don't be misled, first of all, the fan of the external unit turns, but there is no cold air, every 2 to 3 hours out of the cold air, for ten minutes, then I can tell you, there are four common reasons, one of them, excessive freon. Second, the heat dissipation network of the air conditioner is too dirty and the heat dissipation is not good. Third, the pipeline system is blocked.
Fourth, the compressor is slightly jammed. The specific analysis method can be identified by using a clamp ammeter + pressure gauge. Shut down the air conditioner for 2 to 3 hours, hang the clamp ammeter on the line of the power capacitor of the compressor, or the line of the common section, or hang it on the live wire or neutral line connected to the external machine, connect the pressure gauge, turn on, if the compressor starts, check the relationship between the working current and the rated current, if it starts to be higher than the rated current about 1a, and then slowly rises, and the pressure gauge can return to the normal pressure position normally at the beginning, then the compressor is slightly stuck or the heat dissipation is not good or the pipeline is not good, This is to pay attention to the starting sound of the compressor, if it is a humming sound, it is not stuck, if there is a clicking sound, it is a compressor stuck.
If it is a hum, you should pay attention to the pressure gauge back pressure speed, if the back pressure speed is fast and there is no **, there is no dirty blockage, if the back pressure speed is slow and will fluctuate back and forth, it is a pipe blockage. If the pressure gauge can return to the normal position at the beginning, the back pressure speed is fast, there is no **, and the compressor starts with a buzzing sound, then the heat dissipation network is dirty and blocked, and the heat dissipation is not good, resulting in overheating protection. If the refrigerant meter cannot return to normal pressure, but the backpressure speed is fast and there is no **, then it is an excess of refrigerant, if it cannot return to normal pressure, but the backpressure speed is slow and fluctuating, it may be a pipe blockage.
In fact, it's very troublesome, otherwise why are we engaged in maintenance for so many years and have been learning while repairing, and repairing and learning at the same time, because although everything seems simple on the surface, it is very complicated to study thoroughly, and I just briefly analyze the common reasons here. There are also uncommon causes, such as a decrease in the capacitance of the capacitor, resulting in unstable operating current.

Check whether the mode is refrigeration mode first, if it is refrigeration mode, it is time to add fluorine.

Reasons: 1. First of all, ensure that the indoor and outdoor units are clean and have smooth ventilation, which is also the most basic condition to ensure the normal operation of the air conditioner, including the clean indoor filter and outdoor fins. It is recommended to wash at least 2 times a year, depending on usage.
2. The refrigerant leakage of the refrigeration system leads to poor refrigeration effect, thermal protection caused by the increase of exhaust temperature, etc.
3. The compressor, fan and its capacitor and other circuits are damaged, resulting in compressor protection or non-working.
4. The refrigeration system is blocked, resulting in poor refrigeration, compressor protection and other failures.
5. Improper installation or poor working environment, the temperature of the external unit is too high, and the external unit exceeds the normal working environment, etc.
6. The power supply voltage is low or the power supply line is faulty.
7. The fluorine leaks the press or the capacitor is broken.
Solution: 1. 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.
2. Then check the filter screen 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.
3. Check whether the refrigerant is insufficient, that is, the so-called freon, if it is insufficient, add freon, and check whether the cold circulation system is pure and there is a gas leakage, and if there is a gas leakage, you have to make up for the leakage.
4. 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.
5. If the ventilation pipe of the air conditioner is installed for a long time, it may lead to a poor effect of transmitting indoor heat to the outdoors, so that the refrigeration is not obvious.

If your air conditioner's outdoor unit doesn't rotate and the indoor unit only blows air and doesn't cool down, there may be several reasons:
1.Power Issue: First of all, make sure that the power supply of the air conditioning system is properly connected and powered. Check the power plugs and switches to make sure they are not loose or damaged.
2.Protective device triggering: The protective device in the air conditioning system may have been triggered, causing the outdoor unit to stop operating.
This can be caused by current overload, overheating, or other faults. You can try turning off the air conditioning system and waiting a few minutes before turning it back on to restart the protection.
3.Refrigerant leakage: If the refrigerant leaks in the air-conditioning system, the indoor unit may only blow air and not be able to cool down.
Refrigerant is the medium that transfers heat in an air-conditioning system. If the refrigerant leaks, the system will not be able to circulate the coolant properly and therefore will not be able to provide refrigeration. This situation requires a professional technician to inspect and repair the refrigerant leak.
4.Failure or damage: Other electrical or mechanical failures may also cause the outdoor unit to not rotate and the indoor unit to not refrigerate. This may require a sophisticated inspection and repair by an air conditioner maintenance professional.
In this case, it is recommended that you contact a professional aircon repairer as soon as possible to inspect and repair the traces to ensure that the problem is resolved. Please note that these are just some of the common possible causes, and specific issues require further examination and diagnosis based on your aircon system and actual situation.

1. Low outdoor temperature or poor electricity environment. When the outdoor temperature is too low, the outdoor unit of the air conditioner cannot be frosted, and the air conditioner cannot heat. In addition, if the voltage is too low, it may directly affect the cooling and heating effect of the air conditioner.
2. The heating power of the air conditioner is too small. The size of the room is different, the number of applicable air conditioners is also different, if the air in the house is not tightly sealed, the west is sun, etc., the corresponding number of air conditioners should be larger. If the room is relatively large and the number of horsepower to choose the air conditioner is relatively small, it is easy to cause this problem.
3. There is a problem with the capillary or check valve of the air conditioner. Capillary: The capillary network simulates the mechanism of leaf veins and human capillaries, and consists of a capillary with an outer diameter of about the wall thickness and a main water supply and return pipe with an outer diameter of 20mm (wall thickness of 2mm or more).
Check valve: also known as check valve or check valve. It is used in hydraulic systems to prevent the reverse flow of oil or in pneumatic systems to prevent the reverse flow of compressed air.
4. Air leakage from the four-way valve of the air conditioner. A four-way valve is a control valve with four oil ports, and a four-way valve is an indispensable component in refrigeration equipment. If the four-way valve is crossed, some of the refrigerant that should be involved in heat exchange is directly returned to the return pipe from the compressor outlet pipe at the four-way valve, resulting in a decrease in the refrigerant participating in heat exchange, and a decrease in heat exchange efficiency, resulting in insufficient heat production.
5. There is too much dust in the air conditioner filter. The air filter of the air conditioner has accumulated too much dust, and the vents of the internal and external units are blocked by foreign objects. The function of the filter is to adsorb the dust in the air, if the dust is too much and not cleaned in time, the air circulation will be blocked, resulting in the reduction of the air outlet volume, resulting in the heat production in the machine can not be brought out by the flowing air in time, resulting in insufficient heat production.

It may be that the temperature is relatively low now, and it is difficult for the air conditioner to work below -7, which is a normal phenomenon, or it may be that the indoor unit filter and outdoor condenser of the air conditioner are too dirty. One possibility is that the refrigeration system is lacking, measure whether the refrigeration system is deficient in fluorine, and add a little fluorine appropriately. 1. If the air conditioner works in an environment below -7, the wind blowing by the refrigeration unit will not be hot, because the ambient temperature is too low.
2. If the air conditioner filter and outdoor condenser are too dirty, the air conditioner will not be able to blow hot air, and the wind will not be too hot, because it is blocked by debris and the energy is lost. It is necessary to clean the filter and condenser of the air conditioner regularly, and be careful to wait for the filter to dry completely before installing the air conditioner back on. 3. Check whether the refrigerant of the air conditioner is insufficient, if the refrigerant is insufficient, it will cause the air blown out of the external machine to be not hot, so you need to find professional staff to add refrigerant, do not add too much refrigerant, too much refrigerant will also cause the air conditioner to fail, so the amount of refrigerant added is moderate.
After adding refrigerant, check the air conditioning duct for any leakage of refrigerant, and if so, remediate the duct by the way. If the air conditioner leaks refrigerant, not only will the air blowing from the outside of the air conditioner not be hot, but the compressor will stop running after working for a period of time.

1. If you have a problem with the temperature setting of the air conditioner, you can set the temperature with the remote control, and it is recommended to set the temperature when cooling: 26-28 degrees Celsius.
2. If there is a lack of air conditioning refrigerant (freon), you can find after-sales service personnel to check and add it.
3. The compressor problem can only be maintained by professionals, or consider buying a new machine.
4. If the air conditioner filter is blocked, it is best to clean the filter screen once in about 15 days.
5. Do not place items at the air inlet and outlet of the air conditioner, otherwise it will affect the refrigeration effect of the air conditioner, and foreign objects should be removed.
6. The size of the room should be considered when choosing an air conditioner, and if the room is too large, you can also use a cloth curtain and other partitions to reduce the room area.
7. If there is a heat source in the room that affects the refrigeration of the air conditioner, the heat source in the room should be kept at a certain distance from the air conditioner.
8. If the air conditioner is installed unreasonably, you can find the installer to reinstall and arrange.
9. If there is a quality problem in the newly purchased air conditioner, you can contact the merchant for replacement or maintenance.

1. There may be the following factors for the air conditioner not to heat: 1. There is too much dust on the air conditioner, which affects the heating of the air conditioner. Regular cleaning is sufficient.
2. There is a lack of fluorine in the air conditioner, so you can ask a professional to come to your door and add freon. 3. The power supply voltage connected to the air conditioner is unstable, change to a good socket, and then turn on the heating effect of the air conditioner. 4. If the outdoor temperature is too low, the outdoor unit of the air conditioner will be frosted, and the air conditioner has been defrosting in the first few minutes of the heating effect, which makes people misunderstand that the air conditioner does not heat.
At this time, it is enough to wait for a while. 5. The size of the house is also related to whether the air conditioner is heating or not. The house is too big, the heating effect of the air conditioner is not very good, and the temperature felt by the human body is not obvious, so it will be considered that the air conditioner is not heating.
2. Reasons and treatment of the sound of the outdoor unit of the air conditioner: 1. When the air conditioner starts or stops, the sound of the plastic parts of the internal unit expands and contracts due to temperature changes is a normal phenomenon. There are also some pipelines that are deformed due to thermal expansion and contraction, and are attached to the compressor or metal shell, causing resonance.
2. Whether the fixed wall of the internal and external machine is strong, and the loose or deformed wall fixing screws are easy to lead to this situation. 3. Check whether the indoor and outdoor connecting pipes are fixed, and whether there is any collision with the outdoor unit or other objects.

Hello! We're happy to answer for you! If the air conditioner is not refrigerated, the outside unit blows cold air, then you need to check the following problems:
1. Check the filter screen 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. 2. Check whether the refrigerant is insufficient, that is, the so-called freon, if it is insufficient, it is necessary to add freon, and at the same time check whether the cold circulation system has air leakage, if there is a gas leakage, you have to make up for the leakage. 3. If the ventilation pipe of the air conditioner is installed for a long time, it may lead to poor effect of transmitting indoor heat to the outdoors, so that the refrigeration is not obvious, it is best to find a better location to reinstall it, and strive to minimize the ventilation pipe.
4. If the air conditioner is running normally, and everything else is in good condition, but the room does not feel the cold air, and only the air conditioning can be found on the air conditioner outlet, it is likely that the horsepower of the air conditioner is too small, and the space in the room is too large, so it is best to change to an air conditioner with more horsepower.
It is mainly manifested as slow refrigeration or no refrigeration, especially some air conditioners that have been used for a long time, once this situation occurs, people's first reaction is: find a maintenance master to add fluoride! However, what the author wants to tell you is that the lack of cooling of the air conditioner is not necessarily caused by a lack of fluorine. >>>More
The air blowing from the outside of the air conditioner is generally not harmful to the human body. The air blowing from the outside of the air conditioner only heats up the nearby air. The indoor unit converts the air conditioner from liquid to gaseous state while absorbing a large amount of heat and cooling the surrounding air. >>>More
The disassembly of the external unit of the air conditioner is to first compress the refrigerant**, use a tool to disassemble the connecting copper pipe and power cord with the internal unit, and then remove the fastening screws of the base and the support frame. >>>More
