The air conditioner smells particularly bad at night, what s the matter if it s not cool?

Hello. That's because it has been closed and the air is not circulating, so the air smells bad, and it is recommended to open a small opening when turning on the air conditioner or ventilate it once an hour.

First check whether the mode is set correctly, whether the mains power is too high or too low to cause the compressor not to work or the filter screen is too thick to cause poor ventilation, if not, it may be that the air conditioner is faulty, common faults are lack of fluorine, the compressor and its auxiliary circuits (starting capacitor, overcurrent thermal protector) damage, internal and external fan damage, computer board and remote control receiver failure.

It's time to clean up. Hire a professional to clean up. Let's change the filter.

The air conditioner smells particularly bad at night, and if it is fine during the day, it is caused by bad air at night.

If it's humid at night, it may be that the filter is moldy and needs to be cleaned.

Cooling fan, also known as air conditioning, is used to cool the generally well-known water air conditioning: Aollan, Corella, and Jiafeng. As for the appearance is not cool, the smell is unpleasant, because:

1. The water in the air conditioner is water, and if it is not clean for a long time, it will accumulate water, and bacteria will stay in it, and of course it will emit an unpleasant smell for a long time. 2. Not cooled because: The water curtain paper is scrapped and needs to be replaced in time, and there may be a fire pump.

Solution: You only need to replace the new water curtain paper, add feng shui air conditioning for matching sales, and clean the inside of the machine at the same time.

Has your air conditioner not been cleaned for a long time? There is also the air conditioning liquid is gone, it is recommended to let a professional master come and take a look, and clean up the air conditioner by the way.

If there is an unpleasant smell, it means that your air conditioner should be cleaned, and you can remove it and clean the filter to clean the dust.

If the air conditioner is good, but it does not refrigerate, it is likely that there is a lack of freon. Generally, those who repair air conditioners can add fluoride.

If the air smell is particularly bad, it is because the air conditioner needs to be cleaned.

That's a lack of clothes. It's possible that the ashes are big. Or it's blocked. Wash it and you'll be fine.

It is necessary to add refrigerant to clean the indoor unit of the air conditioner.

It is because the air conditioner has not been cleaned for a long time, it may be that the mold has fermented inside, and it is recommended to find a professional to clean it.

Remind you to remove the filter of the air conditioner and wash it, it will produce a rotten smell after a long time. There is also a disgusting situation, but also to open the air conditioning filter, sometimes the home rats and other small animals will run to the air conditioner through the air conditioning pipe to "cool off", after being killed by the fan, it will rot in the body will emit this sour smell, clean it up will be fine.

1. The filter of the air conditioner has not been cleaned for a long time, and there are too many stolen goods in it;

2. Maybe there are small animals (mice, cockroaches, geckos, etc.) that die in it and stink.

Generally speaking, these are the two reasons.

If it is not cleaned for a long time, the air blown out is smelly, which is more harmful to the human body and affects the refrigeration effect. All you have to do is to take apart the air conditioner's filter and other things, remove it and clean the whole set. This will generally solve the problem.

Did something dirty fall inside?

It may be that there is an air leak in the cold circulation systemTo check whether the air conditioner can operate normally, including the indoor unit and the outdoor unit, especially to check the compressor of the outdoor unit, if it is impossible to judge the cause of its failure, it is recommended to find a professional maintenance personnel to check and repair the air conditioner in time.

If it works properly, it may be due to serious dust accumulation in parts such as the filter, disassemble the filter and clean it with clean water and a soft brush. Use a special cleaning solvent to clean the surface of the evaporator.

It may also be caused by insufficient refrigerant, if it has not been added for more than 3 years, you need to ask the maintenance personnel to check and replenish it, and check whether there is any air leakage by the way.

If there are no above problems, the air conditioner can also operate normally, then it is necessary to 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, then it is necessary to replace the new fan motor.

Precautions for the use of air conditioners:

There should also be no obstacles in front of the indoor unit, otherwise the air outlet will be affected.

When the air conditioner is first running, the selector switch can be adjusted to high speed for rapid cooling, and then to medium and low speed when the temperature drops.

When you feel that the use of the air conditioner is not ideal, you should consult the instruction manual, analyze whether it is caused by improper use, find out the cause and correct it.

When the fault cannot be dealt with by itself after being found, it should be repaired in time, and it is not possible to repair it by yourself or find non-professionals for maintenance.

Refrigerant is missing, fan is faulty, compressor is malfunctioningGree's current compressor is produced by the former domestic miscellaneous compressor factory, because the former merged with the latter, and the United States is still wrong.

If the air conditioner starts normally, but the air conditioner can't blow out, it may be that the filter is too dustyYou can also check whether the refrigerant freon is insufficient. It is also possible that there is an air leak in the cold circulation system

In addition, this problem can also occur if the indoor and outdoor units do not operate properlyIn this case, it is recommended to find maintenance personnel to come to the door for maintenance.

The air conditioner is not cool and the solution :

1. To check whether the air conditioner can operate normally, including the indoor unit and the outdoor unit, especially to check 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, and the air conditioner can be refrigerated normally.

2. 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. When cleaning, be sure to disconnect the power supply.

3. Check whether the refrigerant is insufficient, that is, the so-called freon, if it is insufficient, add freon, and check whether there is air leakage in the cold circulation system.

4. If there are no above problems, the air conditioner can also operate normally, then it is necessary to 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, at this time, it is necessary to replace the new fan motor.

5. If the air duct of the air conditioner is installed for a long time, it may lead to the poor effect of transferring indoor heat to the outdoors, so that the refrigeration is not very obvious, it is best to find a better position to reinstall it, and strive to shorten the ventilation pipe.

6. If the air conditioner is running normally, and everything else is in good condition, but the room does not feel the cold air, only to the air conditioner air outlet, it is likely that the horsepower of the air conditioner is too small, and the space in the room is too large, at this time it is best to change to an air conditioner with more horsepower.

If you find that the air conditioner can not be refrigerated normally when using the air conditioner, then you can check it according to the above methods, so as to effectively solve the fault of the air conditioner and ensure its normal operation, of course, if you don't know how to operate.

Then don't forcibly disassemble the air conditioner, in this case, it is best to go to the after-sales service office or ask the maintenance personnel to come to the door for maintenance, maintenance ** is based on the degree of damage to the product, as well as regional differences, you can go to understand the market in advance**.

There are several reasons why the wind is not cool, one is the lack of refrigerant, the second is the fan problem, and the third is the compressor failure.

1. There is a certain degree of leakage or light leakage of refrigerant in the pipeline of the air-conditioning system; 2. The compressor capacitor is aging or damaged, resulting in the attenuation of the capacitor capacity, and the compressor is in the overcurrent state for a long time, and the overcurrent protection is obtained; 3. The heat exchanger of the outdoor unit is too dirty, resulting in the compressor having an exhaust temperature or the exhaust pressure is too high. 4. The capacitance of the outdoor fan is aging and the capacity is attenuated, resulting in the compressor having an exhaust pressure or the exhaust temperature is too high.

Causes and solutions for air conditioners that are windy but not cooling:

1. The compressor has no refrigerant, add refrigerant.

3. The solenoid valve is not reversed: detect whether the solenoid valve is normal, and replace the solenoid valve if it is not on/off.

4. System failure: check whether the capillary is dirty, oil or ice blocked, if the air conditioner is not refrigerated when refrigerating, it is generally ice blockage, if the nitrogen blowing pipeline blows out the stolen goods or is not smooth, it means that the dirty plug or oil blockage, if there is no refrigerant in the open system, the refrigerant leakage, check the leakage point maintenance.

5. Compressor failure: the whole machine is not refrigerated, open the system, check whether there is enough refrigerant spray, determine whether it is refrigerant leakage, no leakage, and check whether the compressor is not exhausted.

Actually, it's time to add a Buddha By the way, just wash it with water and blow it clean with oxygen, not necessarily a lot of words.

Generally, air conditioners do not refrigerate for the following reasons:

1.Freon is not enough (commonly known as not enough refrigerant).

2.The voltage supplied to the power supply is not enough.

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

4.The outside ambient temperature is too high, causing the air conditioner to not refrigerate.

5.The air conditioner is not cleaned and maintained for a long time.

6.The steel pipe between the outdoor unit and the indoor unit is too long.

Check what went wrong, and if you don't understand, ask me.

The inner fan is broken!Find after-sales service.

The voltage is not enough, or the air conditioner is aging.

My air conditioner is not cooled when it is turned on, and the temperature on the indoor unit is 29 degrees, and the wind blowing out is the wind at room temperature.

Cause of failure:

1. During refrigeration, the external condensate is reduced or frosted, and the temperature of the air outlet of the internal machine cannot be lowered, which is a symptom of insufficient refrigerant.

2. The air-conditioning compressor burns out and is caused by the continuous use of the air-conditioner for too long, wear or quality problems of the machine itself.

3. The air conditioner has not been maintained for a long time. If the air conditioner is not cleaned and maintained for a long time, the long-term ignorance of the air conditioner maintenance will make the room air unhygienic, the air outlet will be blocked, and the cold air will not be able to be played; It is also susceptible to air conditioning disease, increased power consumption, shortening the service life of air conditioners, etc.

4. Other parts are damaged, which will also cause the air conditioner to not be refrigerated, and the vulnerable parts include capacitors, temperature sensing heads, circuit boards, etc., which need to be tested by professional technicians.

Remove the air intake net and wash it before trying. If it doesn't work, is it time to add fluoride?

It's time to add fluoride and clean it by the way.

The air blowing from the air conditioner is very smelly, because the air conditioner has not been cleaned for a long time, resulting in a large number of bacteria on the surface of the evaporator and emitting an unpleasant smell.

Reason: The internal evaporator of the air conditioner will produce condensation during refrigeration, condensing the moisture in the air on the surface of the evaporator, the humid environment and the dust attached to the surface of the evaporator, if the cleaning is not timely, it is easy to breed a large number of bacteria, which will not only emit an unpleasant smell, affect the heat exchange of the evaporator, and then affect the respiratory health of the family.

Secondly, if you often smoke, spray perfume, makeup, etc. in the air-conditioned room, then the air conditioner in the room will go through the circulation of the air-conditioning evaporator for a long time, adsorbed on the evaporator or filter screen, after a long time, the air conditioner will have a strange smell when it is just turned on, so the air-conditioned room should be kept clean.

Measures to prevent odors from air conditioners:

1. Regardless of regular or occasional use, the air conditioner should be cleaned regularly.

Second, the air conditioner should be disinfected once a month, and the air conditioner should be thoroughly cleaned and disinfected before the first turn on in the season every year, because people may stay in the air-conditioned room for a long time, the indoor air quality directly affects our health, so the air conditioner needs to be cleaned regularly.

The smell of air from the air conditioner is caused by the fact that the air conditioner has not been used for a long time, the filter screen is blocked, and the air supply outlet of the indoor air conditioner is caused by dust accumulation.

The specific explanation is as follows:

1. Not using the air conditioner for a long time will produce a smell. As the condensate trapped on the heat exchange coils, fins and their peripheral components slowly evaporates, high temperature conditions are formed around the coils that are suitable for microbial reproduction, and a large amount of gas produced during microbial reproduction is released under the drive of the air conditioning system.

2. The filter screen is clogged and produces odor. There is a blockage in the filter inside the air conditioner, which combines with the humid air in the room to produce bacteria, causing the air conditioner to smell when in use.

3. The air supply outlet of the indoor air conditioner accumulates dust and produces odor. Although the air outlet of some ** air conditioners has a very efficient filter system, there is still dust adhesion on the surface of the internal parts of the air conditioner, which is difficult to avoid even in special environments such as computer rooms and hotel rooms where the air has been filtered.

2.Open the surface panel of the air conditioner, remove the filter and air purification filter (some air conditioners have it, refer to the air conditioner manual), and expose the heat sink.

3.Prepare the watering can and add cleaning agent, shake the watering can thoroughly, about 5cm away from the heat sink, and spray the entire heat sink in the order of up and down.

4.After the spray is finished, wait for about 15 minutes, install the filter, and then run the air conditioning and refrigeration program for 15-30 minutes, and the sewage will be automatically discharged with the drainage pipe.

The quality of the environment is something that each of us is very concerned about, especially in some relatively closed environments, a little air pollution is unbearable for us. In the hot summer, we will turn on the air conditioner to reduce the indoor temperature to a comfortable range, but sometimes the air conditioner blows out of the wind smell, which makes us very upset, so not only will not reach a comfortable state, but also make us upset, so what to do if the air conditioner blows out of the smell?

What should I do if the wind blowing from the air conditioner smells?

The smell of air conditioning often makes us very uncomfortable, and sometimes it can even cause respiratory diseases. Then we can remove the odor by the following methods, we can use a special cleaner to wash grease and put it in the watering can to spray the condenser of the indoor unit (that is, the copper pipe and heat sink in the front of the indoor unit are opened), and then pay attention to the following matters.

1: Change the indoor air every 1 hour, simply put, ventilation.

2: Pay attention to the air filter in the room, this air filter can be seen as long as the front panel of the inner machine is opened.

3: Pay attention to let the cleaning company wash the condenser of the indoor unit of the air conditioner for you, and you can also wash it yourself, and open the front panel of the internal unit to see the filter screen.

4: It's best not to use fresh air in an air-conditioned room, the air smells good at first, but after 2 days it smells.

5: During the day, you can put a green plant in a sunny place indoors, preferably without flowering, and without pollen pollution.

6: If the air conditioner is often turned on, pay attention to the humidity in the room when the temperature is lower than 27 degrees, and add less water on the ground if it feels dry.

What is the reason for the smell of the air from the air conditioner?

1. After the air conditioner is used all year round, the indoor filter and copper sheet will squeeze a certain amount of dust, so that after accumulating to a certain amount, a certain odor will be generated, and the air conditioner will be blown into the air with the air conditioner turned on.

2. Because the air conditioner is refrigerated and heated, in many cases, there will be moisture inside the indoor unit, so when the air conditioner is turned off, the air conditioner without dry and mildew prevention function will be shut down immediately, so that the internal moisture has always existed, and mold will be produced in the long run, and the musty smell will naturally occur.

Through the above explanation, I believe that we all have a certain understanding of the peculiar smell of air conditioning and the causes of peculiar smell. In fact, when we use the air conditioner in our daily life, we still have to take good care of and clean the air conditioner regularly, so that the smell of the air conditioner will definitely not come out. We can wipe the air outlet of the air conditioner regularly when we usually use the air conditioner to scrub away some bacteria.

There is also to turn on the air conditioner in moderation, not to turn on it for a day and a night, which is easy to damage the air conditioner.
