The air conditioner is used and suddenly it doesn t cool, what s going on

1. Insufficient freon: The sudden failure of the air conditioner to refrigerate is generally caused by insufficient freon. Because the air conditioner in the process of refrigeration, generally use Freon for refrigeration, and once the use time of Freon is more than three years or so, Freon will be volatilized, once the Freon is not enough, then it will naturally lead to the phenomenon of the air conditioner suddenly not cooling.

At this time, just ask a professional maintenance person to come to help add some freon. 2. The air conditioner is not cleaned and maintained for a long time: the air conditioner suddenly does not refrigerate or may be caused by the air conditioner not being cleaned for a long time, and the air conditioner is used for a long time, and it is easy to accumulate a lot of dust, garbage, etc. on the radiator, which is prone to poor heat dissipation effect, resulting in the air conditioner not being refrigerated or having poor refrigeration effect.

3. Insufficient power supply voltage: The sudden failure of the air conditioner to cool may also be caused by insufficient indoor power supply voltage. If the air conditioner is to start normally, then the power supply voltage needs to reach at least 220 volts, if the power supply voltage is not enough, it will cause the air conditioner to fail to start normally, then the air conditioner will naturally not be able to refrigerate.

4. High external ambient temperature: The sudden failure of the air conditioner to refrigerate may also be caused by the high temperature of the external environment of the air conditioner. When the temperature of the external environment exceeds 33 degrees, and the indoor population is large, the cooling load of the air conditioner will increase, which will lead to a decrease in the cooling capacity of the air conditioner, resulting in the indoor temperature can not be cold.

The voltage is too low for compressor protection.

1.The air conditioner was turned on for half an hour, and when I opened the panel of the indoor unit, I could clearly see that the evaporator was covered with condensate. If there is no possibility of frost or ice in half of the place, it means that the air conditioner is in a state of fluoride deficiency in the area, and it should also be noted that during the operation of the air conditioner, if the lights are on for a while and the lights are off for a while, it also means that the air conditioner is seriously deficient in fluoride.

2.If you have a thermometer at home, you can use it at the air outlet of the air conditioner to measure the temperature difference. If the difference is more than 10 degrees, it means that the air conditioner is operating normally.

However, if the temperature difference of the air conditioner is about 15 degrees, then the temperature is too low and it is a sign of fluoride deficiency. 3.In addition to the indoor unit, the air conditioner also has an outdoor unit.

When we test the outdoor unit, we should touch the two valves of the outdoor unit with our hands after fifteen minutes after the air conditioner is turned on. The resulting temperature difference is relatively large. Frosting in the thin tube indicates a lack of fluorine in the air conditioner, and frosting in the vinegar tube indicates poor circulation in the system.

The second is that the air conditioner does not refrigerate the section wheel, which can be easily solved with only 3 strokes. 1.Although today's air conditioners have heating and cooling functions, some family air conditioners still only have cold air and no hot air.

Every winter, the air conditioner is put on hold until the following summer, so all we need to do is maintain the air conditioner. If the air conditioner is not cleaned and maintained for a long time, a large amount of dust will accumulate on the filter, fan blades, and wind wheel inside the air conditioner, which will eventually lead to a decrease in the temperature of the air conditioner's air outlet. So to remind everyone, the air conditioning definitely is.

2.In summer, the outdoor temperature is relatively high, so it will also cause the temperature of the condenser of the outdoor unit of the air conditioner to rise. If the temperature exceeds the heat emitted by the condenser, then the air conditioner will not work properly.

Watering and shading can make the outdoor unit achieve a good cooling effect. If you turn on the air conditioner at night, the cooling effect will be very good, and there is no need for urgent warranty. 3.

When buying an air conditioner, you will always pay attention to the number of air conditioners. At this time, you have to pay attention. The number of air conditioners must match the size of your home, and there is a direct relationship between the two.

The number of air conditioners is small, the air conditioners are slow to refrigerate, and the number of air conditioners is large, but it is a waste of money. So you need to fully understand the size of your room and choose the most suitable air conditioner.

1. Whether the temperature of the remote control of the air conditioner is adjusted correctly.

2. The air conditioner has not been cleaned for a long time, and the air conditioner will have a lot of dust on the filter screen if used for a long time, and over time, only the dust will block the air conditioner blowing out, resulting in the cold air not blowing out.

3. If the air conditioner is not refrigerated, it is necessary to see whether the air conditioner may lack freon or whether it is freon leakage.

4. The instability of voltage will also lead to non-refrigeration.

5. The number of air conditioners is not enough, and the small number of horses is used in a large area of the house.

6. It is related to the outside temperature and the location of the external unit, if the air conditioner is placed in a space with poor heat dissipation, it will lead to poor air circulation, resulting in slow heat dissipation of the external unit, so that the air conditioner is not refrigerated.

1. It may be that the remote control of the air conditioner is not adjusted to the right temperature.

2. It may be that the air conditioner has not been cleaned for too long, resulting in dust accumulation on the filter screen, which will block the cold air of the air conditioner and not blow out.

3. It may be that the freon leakage in the air conditioner causes too little freon and the air conditioner is not refrigerated.

The air conditioner compressor is broken, fluorine leakage, the temperature control board is broken, etc., the air conditioner generally has a five-year warranty, if it is still in the warranty period, you can contact the manufacturer for after-sales.

It means that the air conditioner may be broken, find someone to fix it.

It could be that the dust is full or the freon is gone.

There are many reasons why the air conditioner suddenly stopped cooling. Let's find a professional master.

The air conditioner not cooling may be due to insufficient refrigerant, and the appropriate amount of refrigerant should be added.

When the refrigerant circulating in the refrigeration system is insufficient, the pressure values on both the high and low pressure sides will be lower than normal, and the bubble flow can be seen from the observation window. At this time, after checking that the air conditioner does not refrigerate the system without leakage, an appropriate amount of refrigerant should be added. If the refrigeration dose charged exceeds the normal capacity of the refrigeration system, the liquid refrigerant in the condenser will inevitably increase, thereby reducing the heat dissipation area and reducing the cooling efficiency.

Air Conditioning Maintenance:

During the mild temperature seasons from March to May and September to November, people generally leave the air conditioner in a non-working state. In the season when the air conditioner is not in use, the first thing to do is to turn off the power supply of the air conditioner; However, it is best to maintain the amount of use once a month to prevent condensation of lubricating oil in the machine caused by long-term non-use. At the same time, in order to ensure the long-term high-speed operation of the air conditioner and the extension of the use mission, it is necessary to pay attention to the proper maintenance of the air conditioner when the air conditioner is suspended and started.

Check that there are no obstacles in the air inlet and outlet of the indoor and outdoor units, so as not to reduce the working efficiency of the air conditioner; Install a dust filter to avoid damage to the machine or cause failure due to dust entering the machine; Wash the remote control with a dry cloth, not a glass cleaner or a cloth containing chemicals, and put two new batteries of the same model in after cleaning.

1. There is a problem with the power supply voltage of the air conditioner, and the unstable voltage will cause the air conditioner to suddenly not refrigerate. 2. The lack of fluoride in air conditioning is divided into two situations, the first is that it has been used for a long time, and it is generally necessary to add fluoride after 5 years of use, otherwise it will lead to no refrigeration. 3. Another situation is the phenomenon of fluorine leakage, which will lead to the normal operation of the mu and no longer refrigeration.

Solution: 1. Find a multi-purpose pen to test whether the voltage at the power supply of the air conditioner is relatively low or the voltage is unstable, if there is a problem with the voltage, you can install a voltage stabilization device or equip the air conditioner with a separate power supply.

2. Contact the air-conditioning after-sales maintenance master to check whether the air-conditioning fluoride is enough, if the manuscript is not enough, first see if there is a fluoride leakage point, first find and solve the leakage point and then add fluoride for the second time.

3. Move the key of the outdoor unit to a more spacious place, so that the outdoor unit can re-dissipate heat.

There could be several reasons for this:

1.The air conditioner filter needs to be cleaned or replaced. If the aircon filter is clogged with dust and dirt, the air flow will be restricted, causing the aircon to not cool.

2.The air conditioner condenser needs to be cleaned. If there is dust and dirt on the condenser of the air conditioner, it will affect the cooling effect of the air conditioner.

3.The air conditioner refrigerant is insufficient. If the air conditioner does not have enough refrigerant, it will not be able to cool effectively.

4.The air conditioner compressor is faulty. If the air conditioning compressor fails, it will not be able to compress the refrigerant into high-pressure gas, and Shannai will not be able to refrigerate.

5.The air conditioner circuit is faulty. If the air conditioning circuit fails, it will not function properly and thus it will not be able to refrigerate.

If your air conditioner suddenly stops cooling, it is recommended that you contact a professional air conditioner maintenance personnel for inspection and repair.

There could be several reasons for this:

1.Air conditioner filters need to be cleaned or replaced. If the filter is clogged, the air flow will be restricted, causing the air conditioner to not cool.

2.The air conditioner condenser needs to be cleaned. If there is dust or dirt on the condenser, it will not be able to absorb heat effectively, which will affect the refrigeration effect.

3.The air conditioner is not sufficient. If the refrigerant of the air conditioner is insufficient, it will not be able to absorb and release heat as a cracking effect, resulting in the air conditioner not cooling.

4.The air conditioner compressor is faulty. If the air conditioning compressor fails, it will not be able to compress the refrigerant into a high-pressure gas, which will affect the refrigeration effect.

5.Faulty electronic controller of the air conditioner. If the electronic controller of the air conditioner fails, it will not be able to control the cooling and closed heating functions of the air conditioner, resulting in the air conditioner not cooling.

If your air conditioner suddenly stops cooling, it is recommended that you contact a professional air conditioner maintenance personnel for inspection and repair.

What's the deal with the air conditioner not cooling? Let's find out.

1. The indoor unit or outdoor unit is not running

First of all, check whether the Chigo air conditioner is operating 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 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.

3. Insufficient refrigerant for air conditioning

The biggest possibility is that the air conditioner has no refrigerant or the refrigerant is insufficient, at this time we can ask professionals to come and add refrigerant to guess the pants.

4. There is a problem with the source or voltage of the electric distribution

Power supply or voltage problems this phenomenon is more common in summer, because in the hot summer electricity consumption is relatively large, seriously exceeding the electricity load, it will lead to air conditioning is not cooling, in this case Suijian also has no better way, at most is to negotiate with the local property to increase the rated power of electricity, and then there is to buy a better voltage regulator.

The above is today's sharing, I hope it can help you.
