Why is the air outlet of the air conditioner not hot?

This is usually normal, as the comparison is based on the outside temperature. If it's hot, adjusting to 28 degrees should be appropriate. If the outside temperature is very low to 28 degrees, it may feel cold.

Maybe the air conditioner was moved recently with refrigerant. If refrigerant is added, the cooling effect of the air conditioner is significantly better than before. Specifically, it is necessary to check whether the outdoor compressor is working when the hot air is blown.

If not, it is most likely that the compressor is shut down for thermal protection. If the compressor is working, it is most likely due to the failure of the four-way valve. You have to contact the after-sales maintenance in time.

Maintenance after shutdown: The air conditioner turns on when the weather warms up, and the air conditioner turns off when the weather gets cooler, which is a perennial rule. Pay attention to perform a thorough and detailed inspection of the outdoor unit and indoor unit before the air conditioner is turned off.

Maintenance, maintenance, and cleaning should be carried out one by one, and cannot be disjointed. Leaked links should be pinned and rigorously checked. After the above links are completed, cover the air conditioner to prevent dust pollution.

Prevent the air conditioner from dripping into the water, keep it clean, prepare for reuse in the next year, clean and energy-saving, and prolong the service life of the air conditioner. Focus on protecting high-quality split machines and cabinets of well-known brands to give full play to the energy-saving effect.

First determine whether the external machine is working, on two points, one, whether the compressor is rotating, two, whether there is a lack of freon, to see if it is a lack of fluorine, it is best to detect leaks first, and then vacuum quantitative fluorine, in order to ensure a good effect

Pro, the poor refrigeration effect of the air conditioner may not produce hot air from the outside machine may be the following situations1The refrigerant of the indoor mechanism is blocked, so that the suction pressure of the compressor is reduced, the pressure of the high-pressure side increases, and the overload and overcurrent protector is started, so that the compressor is stopped. 2.

Outdoor unit protection, outdoor unit heat dissipation (cold) is poor, such as ice or dust accumulation, etc. 3.The reason for the thermostat, the start and stop of the compressor during heating is controlled by the thermometer, and the heating is higher than the target temperature and the lower temperature is 4

The power supply voltage is low, the capacity is insufficient, and the wire diameter does not meet the requirements, which often causes the compressor to start frequently during the peak period of electricity consumption, so that the air conditioner can not work normally. Just replace the power cord or request an expansion to solve the problem. The power of the air conditioner during heating is half that of refrigeration, and the starting current is larger, so it may cause tripping.

In addition to this, line control failures are also common. For example, if the external machine is not working, it is most likely that the capacitor is called Mingkai, the temperature probe or the motherboard is faulty. These faults can only be determined after the maintenance personnel of the air conditioning manufacturer or professional repairers come to inspect the site.

This means that the air conditioner is in a state of protection. The compressor stopped. If it is confirmed that the external unit is not very dirty, there is no trace of oil at the pipe cut-off door.

Then you can only find a maintenance master. Because there are many reasons for protection. Only a professional can be sure if it has been checked,

I'm still a little confused, can you be more detailed?

The air conditioner is not hot.

1. If the air conditioner is not hot, first determine whether the outside unit is working, and then there are two points: 1. Whether the compressor is rotating; 2. Whether there is a lack of freon, depending on the lack of fluorine, it is best to detect leaks first, and then add fluoride quantitatively in a vacuum, so as to ensure a good effect. 2. When the air conditioner is in refrigeration mode, there should be wind blowing out when it is turned on, but when using the heating mode, the air conditioner needs to be preheated for 3-5 minutes after turning on to prevent cold air from blowing.

Therefore, the indoor fan does not start for the first 3-5 minutes, after which the air will be emitted normally. 3. If your machine is turned on for more than 5 minutes and there is no wind blowing out, you can apply for repair through the official website, and the engineering nuclear suspect will come to deal with it for you. Extended Information:

Air conditioning cleaning is an important part of the maintenance of air conditioning units, which is conducive to improving the refrigeration effect, shortening the refrigeration time, saving energy of the air conditioning unit, prolonging the service life of the air conditioning unit, and the rational use of the air conditioning unit. In the past, air conditioning users did not pay enough attention to the maintenance and cleaning of air conditioners, and should strengthen this aspect of work to promote the development of the air conditioning industry. Air-conditioners should be thoroughly cleaned and disinfected before they are first activated at the end of each season.

The above is the solution to the air conditioner's external unit not being hot, you can also choose to find foreign aid, call ** to the official website for maintenance, but there must be a charge.

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.

Summary. There are several reasons for this situation: 1. Wind and non-refrigeration caused by lack of fluorine. 2. The air conditioner is not installed properly, and the copper pipe is too long, resulting in excessive loss of cold air transmission. 3. The installation position of the outdoor unit is incorrect.

The reasons for the occurrence of this situation are as follows: 1. Wind and non-refrigeration caused by lack of fluorine. 2. The air conditioner is not installed with a good stool, and the copper pipe is too long, resulting in excessive loss of air conditioning. 3. The installation position of the outdoor unit is incorrect.

Suggested solutions: 1. If the fluoride is not added at the beginning, the air conditioner will be short of fluorine, resulting in the decline of the air conditioner's ability to cool down or not refrigeration. 2. When the air conditioner is installed, the location is not right, and it is not installed well, resulting in the air conditioning copper pipe is too long, and the air conditioning cold air is transmitted and lost too much in the air conditioning condenser pipe, resulting in the deterioration of the air conditioning refrigeration capacity.

3. Some families buy ** air conditioner, ** air conditioner has a problem with the ventilation pipe, resulting in ventilation problems, which affects the refrigeration capacity of the air conditioner; 4. If the outdoor unit of the air conditioner is not in the outdoor ventilation place, when the outside ambient temperature is very high or very low, the outdoor unit protector of the air conditioner will automatically trip, resulting in the air conditioner not being refrigerated. If you have tested the above quietly and still cannot solve the problem, it is recommended to directly ask a professional to come to the door for repair.

The refrigeration effect of Gree air conditioner is poor, the drainage will not be cool, and the wind blown out by the external unit will not be hot.

Hello. Then the drain rolls out of the exhaust wind without ice.

Get lost. This can be due to the following reasons:1

Insufficient gas stimulation: If the gas inside the air conditioner is insufficient, it may lead to poor refrigeration effect and problems such as the lack of heat from the air blowing out of the external unit. Therefore, it is necessary to check whether the gas filling capacity of the air conditioner is sufficient.

2.Filters need to be cleaned or replaced: If the air conditioner's filter is too dirty or too old, it will affect air circulation and refrigeration, so the filter needs to be cleaned or replaced regularly.

3.Failure of electronic components: If the electronic components inside the air conditioner are damaged or the socks are faulty, it may also lead to problems such as poor cooling effect of the air conditioner and the lack of heat from the air blowing out of the external unit.

4.Anti-freezing of the external machine: If the pipe of the external machine is frozen, the air blowing out of the external machine will not be hot, and the problem of icing of the external machine needs to be solved in time.

To sum up, it is recommended that you contact a professional air conditioner maintenance personnel for inspection and maintenance.
