What is the reason why my Midea air conditioner only heats and does not cool?

The reasons why Midea's air conditioner does not refrigerate are:

1. Lack of refrigerant.

As long as there is enough refrigerant in the car air conditioner, then there will definitely be a better refrigeration effect.

2. The compressor capacitor is damaged or defective, resulting in the compressor not working.

3. The inside of the air conditioner is too dirty.

It is the pipe blockage, the refrigerant can not complete the normal cycle, the air conditioner can not be refrigerated, at this time, the air conditioner should be cleaned and maintained, and the maintenance of the car air conditioner should be better done by professionals, and the personal ability is not enough.

4. The condenser is blocked by dust.

There may be a situation where the air conditioning filter is blocked, and if the refrigerant of the car air conditioner is missing, there will also be a situation where the refrigeration effect is not significant, and if the refrigerant is insufficient, it is necessary to find a professional maintenance personnel to add fluoride.

5. Excessive refrigerant filling during maintenance.

In an air-conditioning system, there are certain requirements for the proportion of refrigerant in the volume. If the proportion is too large, it will affect its heat dissipation, that is, the more heat dissipation, the greater the cooling capacity; Conversely, if the heat dissipation is less, the cooling capacity will be small.

6. The control panel of the internal or external unit of the air conditioner is faulty, resulting in the air conditioner not being refrigerated.

7. The internal or external fan is damaged, the capacitor is more bad, the external fan is too high the exhaust temperature or high pressure is too high protection, and the internal fan is bad, the internal machine is frosty, the external machine has been working, and the internal machine has no moisture.

What is the reason why the Midea air conditioner at home only heats and does not cool? If the Midea air conditioner at home only heats and does not refrigerate, it means that your cooling is not enough, like this you can buy some refrigerant to add it.

The so-called automatic air conditioner is usually centered on 25 degrees Celsius, and the room temperature is higher than this temperature, and the air conditioner automatically cools and automatically heats up when the temperature is lower than here. Therefore, he can generally only choose cooling and heating automatically. However, you can try to increase the set temperature to achieve heating.

It is not as good as the current room temperature of 26 degrees, and the refrigeration step will be automatically run according to the machine setting. At this time, you can adjust the set temperature, try it to 30 degrees, and some models will have this reaction and heat directly.

It should be that the refrigeration system is broken, or there is no control of the function key of refrigeration, and this refrigeration option cannot be selected.

1. It may be that the setting mode is wrong, such as adjusting to the refrigeration mode, when this problem is solved, then press the remote control to the heating, and adjust the temperature to use it normally. 2. If the air conditioner lacks fluoride, it will also lead to no heating, and freon should be supplemented in this case. 3. If the filter screen of the air conditioner is blocked, the air outlet will not heat if the air outlet is not smooth, so the filter screen should be cleaned.

What to pay attention to when using air conditioners for heating in winter.

1. Don't turn on and off the air conditioner often, which has a great impact on the life of the air conditioner, because when the air conditioner is turned on, the current is very large, and it is easy to damage the fuse, which is also a kind of damage to the compressor of the air conditioner, and it will also affect the heating effect.

2. If the filter is not cleaned, it is easy to accumulate dust, which is harmful to the human body and respiratory health, and the dust blocks the air outlet, and the hot air cannot be discharged if the air outlet is not smooth, and it is easy to damage the internal components, and the heating effect will naturally be very poor.

3. When cleaning the filter, you should use a special cleaning agent, not a strong acid and alkali cleaning agent, not to mention exposure to the sun, or a brush, which can easily cause the filter to deform and cannot be used.

4. When using the air conditioner, the temperature should not be adjusted to the highest at once, so that the loss of the compressor is very large, and it is not energy-saving, the temperature should be added slowly, and the indoor heating temperature should not exceed 22 degrees.

5. When using the air conditioner, the doors and windows should be closed to prevent the loss of heating, resulting in frequent opening of the compressor, and in use, do a good job of ventilation once every 2 hours to discharge the polluted air.

First of all, check whether the air conditioner has a heating function, if the heating function, adjust the remote control to the heating mode, the temperature is adjusted to 30 degrees, if the indoor temperature is relatively low, it will have a heating function.

Answer: Hello, there are the following situations in which the air conditioner only cools and does not heat: 1The air filter of the air conditioner has accumulated too much dust, resulting in the blockage of the vent of the external unit, and the air filter can be cleaned to return to normal.

2.In the cold winter, when the ambient temperature is below -5 degrees, the air conditioner cannot heat effectively.

3.The lack of refrigerant in the air conditioner leads to a decrease in the heat exchange efficiency, and the air conditioner will not heat when the heat is insufficient.

4.The defrosting controller of the air conditioner fails, so that the air conditioner does not turn into the defrosting operation state in time, which affects the heating effect of the air conditioner and causes the air conditioner to fail to heat.

If it is a new purchase, find a merchant for repair.

It may be due to the fact that there is too much dust on the filter screen, so try to replace it.

One of the reasons: freon is not enough (commonly known as "refrigerant" is not enough) when the ambient temperature is about 35 degrees Celsius 1, low pressure and high pressure 3, static pressure This is a normal situation, generally appearing in the old air conditioner that has been used for three to four years. The air conditioner did not completely stop cooling, but the effect of cooling decreased.

This is because old air conditioners use freon as a refrigerant, which will volatilize after long-term use. Therefore, users only need to add a little to the regular air conditioning maintenance point. In addition, it is not excluded that improper installation can cause freon leakage and problems with the machine itself.

Reason 2: The power supply voltage is not enough, and the normal starting voltage of the air conditioner is 220V+-10%. In China's power supply system with a phase voltage of 220V and a line voltage of 380V, almost all compressors above 200V can be started.

At 180V or more, 70-80 can be started, and at 160V or more, only a few can be started. I've done it myself. Below 160V there is almost no possibility of starting.

As a rule of thumb, the compressor starting voltage is more reliable above 190V. Reason 3: The general selection principle of air conditioning power is not enough:

150-250W square meters for cooling and 250-350W square meters for heating, in addition to the space height, level orientation, sealing performance and residential population and other factors. Reason 4: There is a more common saying that the outside environment temperature is too high

When the outdoor unit is in an environment above 43°C, it is difficult for most air conditioners to transfer heat from the interior to the outside, resulting in no cooling. Reason 5: The air conditioner is not cleaned and maintained for a long time.

In addition to the problem of incorrect setting and adjustment, it should be caused by the failure of the control circuit of the air conditioner, or the four-way valve is stuck and does not return.

It is recommended to contact after-sales service or ask a professional for maintenance.

First of all, when using the air conditioner in daily life, you must check whether the mode of the basic setting of the air conditioner is correct, some people set the wrong mode, of course, the machine will not work normally. The temperature of the air conditioner should also be set reasonably, and it is recommended to set it at 28 degrees to 30 degrees. The room should be closed and not ventilated.

In short, the heating of the air conditioner is to take the temperature from the outside, and the outdoor temperature is too low, the worse the heating effect of the air conditioner. Therefore, the outdoor temperature is also the reason that determines whether your home's Midea air conditioner can heat up.

Midea air conditioning does not heat or the effect is not good, it also depends on whether the number of machines bought is in line with the room area, the room is too large to affect the effect of the heat can not go up, the air conditioning itself heating is normal, but if the auxiliary electric heating is not turned on, there is also a part of the heating less. The filter screen of the air conditioner should also be cleaned frequently, if there is too much dust attached, then it will cause insufficient circulating air. If it blows out, the hot air will not be enough, and there is also a lack of fluorine, which will also lead to insufficient heating of Midea's air conditioner.

The air conditioner does not clean the filter in time after a long time and the air circulation inside is blocked, which will affect the heating effect of the air conditioner to a certain extent. If the dust scale of the evaporator and condenser is too thick, it will also reduce the heat exchange effect, resulting in a decrease in heating capacity and an increase in power consumption; The heating temperature is set too low; However, the door cracks and wall holes in the air-conditioned room are not blocked, or the windows and doors are opened frequently, resulting in indoor heat loss, which will inadvertently cause the air conditioner heating to be not strong. The outdoor temperature is too low to cause the air conditioner to not work normally, generally the outdoor is below zero, and the outdoor of the inverter air conditioner is about minus 15 degrees Celsius can no longer heat normally, so it may be that the outdoor is too low, the air conditioner cannot defrost, 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.

1. Insufficient refrigerant for air conditioning.

2. Air conditioner four-way valve string air.

3. The defrosting controller is out of order.

4. The auxiliary electric heating function fails.

Summary. Dear, glad to answer for you. <>

There are six solutions to the reason why <> Midea's air conditioner does not refrigerate, the first one may be because the freon is not enough, and only a little need to be added. The second type of supply voltage is insufficient. The third type of air conditioner is not enough power, as long as it is 150-250w square meters when cooling.

It is also possible that the temperature difference between indoor and outdoor temperature is relatively large, it may be that the air conditioner has not been clean for a long time, and it may be that the copper pipe is too long. The details are as follows:

Midea air conditioners can only heat and not cool.

The pro-file banquet is poor, and I am happy to answer for you. <>

There are six reasons why <> Midea's air conditioner does not refrigerate, and the first one may be because the freon is not enough, and you only need to add a little bit on the line. The second type of supply voltage is insufficient. The third type of air conditioning power is not enough, as long as the refrigeration is 150-250w square meters.

It is also possible that the temperature difference between indoor and outdoor temperature is relatively large, it may be that the air conditioner has not been clean for a long time, and it may be that the copper pipe is too long. The details are as follows:

1. The biggest possibility is that the freon of the air conditioner is not enough, if your spring air conditioner has been used for three years or more, the refrigeration effect decreases or does not refrigerate. You just need to ask the after-sales maintenance personnel to add a little bit to it. In addition, it is not excluded that improper installation can cause freon leakage and problems with the machine itself. 2. It is also possible that the power supply voltage is not enough, because the normal starting voltage of the air conditioner is 220V+-10%.

Generally, in China's power supply system, almost all compressors above 200V can be started. When it is above 180V, there are 70-80 that can be started, and when it is above 160V, only a few can be started, if the power supply voltage is too low, it will affect the normal operation of the air conditioning product;

3. The power of the air conditioner is not enough, if your indoor inspection space is relatively large, the refrigeration speed of the air conditioner will be relatively slow, you need to pay attention to the choice of air conditioning, 150-250w square meters when cooling, 250-350w square meters when heating, in addition, it is also necessary to comprehensively consider factors such as space height, level orientation, sealing performance and residential population; 4. It is also possible that the external ambient temperature is too high, if the temperature difference between indoor and outdoor is relatively large, the refrigeration efficiency of the outdoor unit will be relatively low, so the refrigeration efficiency will be slow or even unable to refrigerate; Count the oranges.

5. If the air conditioner is not cleaned and maintained for a long time, the effect of the radiator will be affected due to dust accumulation and other reasons, resulting in the reduction of the refrigeration effect of the air conditioner. If the indoor unit is not cleaned for a long time, it will also be related to the health of the human body, and if it is not cleaned for a long time, bacteria will breed and pollute the air; 6. The copper pipe connecting the indoor unit and the outdoor unit is too long, and the maximum allowable length of the connecting Lingqi number pipeline of the general air conditioner shall not exceed 8 meters, the longest length of the horse shall not exceed 10 meters, and the maximum length of more than 2 horses shall not exceed 15 meters. The height difference between indoor and outdoor units shall not exceed 5 meters.

Is it possible that the motherboard of the external machine will be broken?

Hello, dear, this is a normal phenomenon, and it is unlikely that the motherboard of the external machine is broken!

Midea air conditioners can cool but not heat.

1. The air conditioner itself does not have a heating function, check whether the air conditioner has a heating function, and you can see whether it has a heating function written on the manual.

2. It may be that the room temperature is higher than the set temperature, this is the air conditioner will not start the heating mode, and it is okay to start the refrigeration, it is recommended to reduce the set temperature of the air conditioner to make the air conditioner heating normal operation.

3. The four-way reversing valve of the air conditioner can not rotate normally, the air conditioner needs the four-way reversing valve to turn to heat from refrigeration to heating, if the air conditioner cannot be heated, it is very likely that there is a problem with the four-way valve, check whether the four-way reversing valve is stuck or faulty, and replace the four-way reversing valve.

4. Because the hang-up is controlled by the remote control, it may also be that the remote control is faulty, if the other buttons of the air conditioner are normal, only the heating button is invalid, or it may be that the remote control circuit of the heating button is short-circuited or short-circuited, you can try to use another remote control to try it, if it can be explained that it is a problem with the remote control, replace the remote control.

What is the four-way reversing valve for air conditioner.

The four-way reversing valve of air conditioning can change the flow channel of air conditioning refrigerant and change the flow direction of refrigerant, which is mainly used for cold and hot air conditioning to carry out refrigeration and heating conversion equipment, and is an indispensable part of cold and warm air conditioning and refrigeration and heating.

What should I do if there is a problem with the remote control of the air conditioner.

If there is a short circuit or open circuit phenomenon of a button, turn on the remote control, first wipe the circuit board with cotton dipped in a little pure alcohol, and then install it back to see if it works, if not, it is recommended to buy a universal remote control online, or you can buy a remote control of the same model after the sale.
