What is the reason why the air conditioner does not cool but blows hot air?

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.

You must know that the refrigerant in the air conditioner is not a consumable, if there is no installation problem in the initial stage, the air conditioner will not leak fluorine, and it can operate normally for at least 10 years! And the statement that air conditioners need to be fluoridated every year is a pure rumor!

Air conditioner outdoor unit maintenance

Every summer, once the air conditioner is not refrigerated, there are many friends who go to the third-party maintenance master to "add fluoride", so they are pitted for three or five hundred yuan, and after adding fluorine, it is still not refrigerated, and they are told by the maintenance master that it is due to the aging of the air conditioner, the damage to the motherboard, etc., and the accessories need to be replaced, and then more maintenance costs are charged. In fact, in many cases, if the air conditioner is not cooled, it is not necessary to add fluoride at all, and you can do it yourself at home!

Clean the indoor unit filter and fins

If the indoor unit of the air conditioner is not clean for a long time, it is easy to accumulate dust, breed bacteria, produce peculiar smells, threaten health, and also lead to a decrease in refrigeration performance, which is due to excessive dust attached to the heat exchanger fins, which seriously affects the heat exchange efficiency, and the performance is that the air conditioner is not refrigerated.

Household air conditioners should be washed frequently

The solution is also very simple, that is, to clean the air conditioner, many friends may want to go to the master again, this is not necessary at all, you can easily do it at home. To put it simply, it is divided into three steps, first lift the outer case, remove the strainer, put it under the faucet and rinse it with a brush and dry it. A special air conditioner cleaner is then evenly sprayed on the heat exchanger fins and left to stand for 15 minutes.

Finally, replace the filter, cover the case, and run for a while, and you're done! How, isn't it simple? The cleaned air conditioner not only has high refrigeration efficiency, but also has no peculiar smell, and the output air is clean and clean, caring for respiratory health.

The voltage adaptability of inverter air conditioners is better

Generally speaking, the normal starting voltage of the air conditioner is 220V 10%, and the voltage standard in China is 220V, and almost all compressors above 200V can start. However, due to some special reasons, the supply voltage will be unstable, resulting in the failure to reach the normal voltage, such as during the peak period of electricity consumption. Compared with fixed-speed air conditioners, inverter air conditioners have a stronger ability to adapt to voltage.

This problem cannot be solved by maintenance, and the best solution is to maintain a normal supply voltage.

Then I guess it's the reason why you turned on the heating function.

If the air conditioner is broken, then it is impossible to produce hot air.

Hello, here's why:

1. Refrigerant leakage. (It is manifested that the internal and external units are working, and the compressor is also working, but it is ineffective).

2. The compressor capacitor is damaged or defective, resulting in the compressor not working. (The phenomenon is similar to the above, but the compressor does not rotate and overheats).

3. The resistance value of the temperature sensing head at room temperature changes, resulting in the air conditioner not working. (The phenomenon is the same as when the air conditioner stops at a set temperature).

4. Poor remote control or air conditioner receiver. (It is manifested as no response from the air conditioner when it is turned on, or it does not work from time to time).

5. Four-way valve (single chiller does not have this fault) or compressor high and low pressure string, air conditioning works but has no effect. (The phenomenon is the same as the first).

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

1. First of all, check whether it is the refrigeration mode, if so, check it down. 2. Confirm whether the air conditioner is a heating and cooling machine, if so, see if there is a problem with the four-way valve and engage in the refrigeration situation. 3. If the air conditioner is a single chiller, it is impossible to produce hot air, and the worst is to blow the wind at room temperature.

4. There is another situation that is more dangerous, that is, the heating pipe in the refrigeration and heating machine also works in the case of refrigeration, if this situation occurs, it should be eliminated as soon as possible, otherwise it is very dangerous.

It may be that there are too few refrigerants such as freon in the air conditioner. What is the refrigerant of air conditioning, generally speaking, the refrigerant of air conditioning is freon and refrigerant new refrigerant, and now the advanced technology of air conditioning uses refrigerant new refrigerant for refrigeration. Air conditioning refrigerant does not need to be added frequently, as long as the air conditioning system is well sealed, it can be avoided for several years, and only when the machine begins to have poor refrigeration effect, then consider whether to add refrigerant.

Some air conditioners use freon for refrigeration, if there is a sudden lack of refrigeration, it may be because the fluoride is used up, and a professional can add fluoride.

It should be a sudden change in mode.

You use the remote control to change the refrigeration mode to try, if it can't be cooled, it is broken and needs to be repaired.

If it can be refrigerated, it is estimated that it will be disturbed. Observe again.

The operation of the external unit is generally leaking refrigerant. If the external unit does not rotate, first replace the starting capacitor, if it does not work, the compressor is generally damaged.

It could be that the mode of operation is wrong.

The air conditioner is out of gas, need to refuel.

What is the reason why the air conditioner does not cool but heats up?

First, the most common reason for the lack of fluorine air conditioning is the lack of fluoride, which is a normal situation, generally appearing in the use of three to four years of old air conditioning, long-term use will volatilize off the refrigerant, in addition to improper installation caused by freon leakage and the machine itself problems.

Second, the voltage of the power supply is not enough to supply the unstable voltage of the power supply, and often the normal voltage cannot be reached, which will also cause the air conditioner to be unable to cool and heat normally, 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.

Third, the power of the air conditioner is not enough, which is also one of the common reasons for not cooling and heating, but there are many reasons for this phenomenon, such as: small power air conditioning pipes in a large area of the room, and some although the air conditioning power and the room area seem to match, but because the room is relatively unsealed (such as doors and windows are wide open, etc.) and so on, it will also cause the air conditioning to be cold or heat is not enough.

Hello dear, I'm glad to answer question 1 for you, consider whether Fo Li Ang has, if not, you will have to add Verion. 2. If there is no hot air at the air outlet of the outdoor unit, if not, it is likely that the thermal protection makes the compressor not work, resulting in the situation that the cooling is not cooled. 3. Look at the setting mode on the remote control, if the mode is correct, it means that the four-way valve is broken or the computer board is broken, replace the four-way valve or computer board.

Hello, glad to answer for you! If you think my answer solves the problem for you and is not bad, can you give it a thumbs up? Wishing you good health and a happy mood!

First of all, check whether the mode of the air conditioner is adjusted to heat, if not, it may be that there is not enough refrigerant or there is a problem with the circuit, it is recommended to find someone to add refrigerant to you.

Hello 1Refrigerant leakage: It is manifested that the internal and external units are working, and the compressor is also working, but the refrigeration mode is ineffective;

The compressor capacitor is damaged or defective, causing the compressor to not work;

The change of the resistance value of the temperature sensing head at room temperature causes the external unit of the air conditioner to not work, and the phenomenon is the same as that of the air conditioner when it reaches the set temperature.

Poor remote control or poor air conditioner receiver, which is manifested as no response of the air conditioner when turned on;

Four-way valve or compressor high and low pressure string gas, air conditioning work but no effect.

Use the air conditioner pressure gauge to measure the internal pressure value of the air conditioner, and check whether the refrigeration dose of the air conditioner is missing or insufficient; Secondly, check the condenser (outdoor window unit is working properly).

There are many reasons why the air conditioner is not refrigerated, such as refrigerant leakage, compressor damage, radiator problems, internal unit problems, etc.

It is recommended to find your air conditioner professional after-sales service to have a look.

The air conditioner has two keys for refrigeration and heating, if you click the refrigeration button, you will blow cold air, and if you press the heating button, you will blow hot air. In this case, you should have pressed the wrong key.

There are several reasons for the air conditioner to blow hot air, first check whether the mode is selected wrong, the reason must be the reason for the refrigeration mode to produce cold air, and then check whether the compressor is started, the compressor is not started and not refrigerated.

It may be a refrigerant leak: it is manifested that the internal and external units are working, and the compressor is also working, but the refrigeration mode is ineffective;

If the air conditioner does not cool but blows cold air, then you may have chosen the wrong switch of the remote control, selected the heating function, and the air conditioner is out of order.

The main reason why the air conditioner does not refrigerate but blows hot air is that there is no refrigerant in the air conditioner, and refrigerant can be added to solve the problem of blowing hot air.

To be honest, what brand of air conditioner are you so bad, you directly replaced a new air conditioner, if there is in the afternoon, the time is relatively long when you look for the after-sales air conditioner, and it should be able to be repaired for free

The air conditioner does not refrigerate, but blows hot air, I think the refrigerant is broken, you can find a professional repairer to repair it.

One of the reasons why the air conditioner does not refrigerate but blows hot air is that the outside environment is likely to be very cold, or the air conditioner is not set up successfully.

Pay attention to observe whether the computer settings are set to a hot air shield, so that it is possible to blow out hot air, re-shut down, manually set or refrigeration mode, and then see if it is normal, if it is not normal, it is a problem with the control circuit.

The air conditioner is not refrigerated, what is the reason for the cold wind to blow? If the air conditioner is not literate, if it is cold, it may be that the freon refrigerant is faulty, too little reason, it may be that it is important that this reason is not refrigerated and the wind blows is this reason, or the format of the air conditioner is not right.

What is the reason why the air conditioner does not cool but blows hot air? I think you can ask the maintenance personnel to take a look at this and see if he is not out of the cold air, malfunctioning, or is it an operation problem?

The reason why the air conditioner does not cool the hot air:

1. Sensor failure, the internal heat exchanger coil temperature sensor has the highest damage rate, even if it is not broken, the failure rate detected by it is relatively high, if the sensor is wrong, you may wish to check and replace the sensor.

2. If the contact of the connectors of the air conditioner is poor, check the installation of each part of the air conditioner, whether the plugs are disconnected or not plugged in, and replace and reinstall the damaged plugs.

3. Lack of fluoride is also a common fault, in the case of protection after the air conditioner works for a period of time, the first thing should be checked whether the refrigeration effect is good, if it is not good, the three pressures of the air conditioner must be measured, and then the air conditioner is fluoridated.

4. For power supply voltage problems, check whether the internal contact of the main power switch is good, whether the current resistance is satisfied, whether the total power cord is too long and too thin and whether the voltage is lower than 200V. Whether the neutral wire and the ground wire are mixed, whether the three-phase phase wire and the neutral wire are mixed, etc.

5. Pressure protection, compressor overload protection, common in summer when the temperature is high and the electricity peak is common, turn off the air conditioner and restart.

Summary. Hello, glad to answer for you! Pro, the reason why the air conditioner does not cool and blows hot air (1) The reason why the air conditioner suddenly does not refrigerate.

1. The refrigeration state is set at the end of the controller or the set temperature is too high;

2. The power supply voltage of the main engine of the air conditioner is not enough, so that the main engine cannot be started;

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, it is not excluded that the copper pipe of the host itself is broken, such as: the connection of the evaporator, condenser or the pipeline of the unit itself;

The air conditioner doesn't cool and blows hot air.

Hello, glad to answer for you! Pro, the reason why the air conditioner does not refrigerate and blow hot air (1) The reason why the air conditioner suddenly does not cool 1, the refrigeration state is set at the end of the controller or the temperature is too high; 2. The power supply voltage of the main engine of the air conditioner is not enough, so that the main engine cannot be started; 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, it is not excluded that the copper pipe of the host itself is broken, such as: the connection of the evaporator, condenser or the pipeline of the unit itself;

4. The compressor of the main engine of the air conditioner is burned out. (2) The solution to the sudden non-refrigeration of the air conditioner 1, the air conditioner will come with freon when you buy it, you can add it yourself, or you can find a maintenance master. 2. Try to shorten the length of the copper pipe between the outdoor unit and the indoor unit of the air conditioner.

3. Clean and maintain the air conditioner, and the clean outdoor unit is easier to dissipate heat. 4. Ensure the stability of the voltage at home, especially during the peak period of electricity consumption, buy a high-point resistor and voltmeter to monitor the voltage at all times. 5. Change the use environment of the outdoor unit, and install it in a well-ventilated place.

Dear, you refer to the above hope the above will help you

Just add fluoride and then blow a cold air, and after a few hours, the hot air blows again.

Wait, dear.

1. Consider whether the refrigerant exists, if not, you have to add refrigerant, if not, there will be this situation 2, you go to the air outlet of the outdoor unit to feel whether there is hot air, if not, it is likely that the thermal protection makes the compressor not work, which leads to the situation that you set up the cooling system without refrigeration 3 Look at the setting mode mode on your remote control The mode is correct, that is, the four-way valve is broken or the computer board is broken, find someone to repair it.
