What are the reasons for the failure of the air conditioner fan to operate normally, but it cannot b

Generally, if there is a problem with the refrigeration circulation system of the outdoor unit or the air conditioner, you need to check whether the outdoor unit of the air conditioner is running, and if it is not running, you must ask professional and technical personnel to check whether there is a problem with the electrical part of the air conditioner, whether the compressor is damaged, and whether the fan motor is short-circuited. Whether the starting capacitor has no capacity, and so on. If the external unit is running normally, it is necessary to check the refrigeration circulation system of the air conditioner, whether the system leaks fluorine, whether it is dirty and blocked!

First of all, you should check whether the parts of the air conditioner are blocked. Because the blockage of filters, condensers, air pipes, etc., will cause low refrigeration efficiency, it is easy to feel that the air conditioner is not cooling. In fact, there are many reasons why air conditioners are not cold, so you need to understand why they are not cooled.

You can check 1Whether the air filter is stuck to the dust and impermeable (to be cleaned frequently) 2After the machine is turned on and running, whether there is water coming out of the outdoor unit (if the water does not come out, the refrigerant is leaking), the starting capacitor of the compressor of the external unit is broken.

Solved: Replace the starting capacitor. Galanz's air conditioning is not good, my family used to use it, the noise is the same as the ** car, there are such and such problems at every turn, this year's May Day went to Suning to complete the Whirlpool horse, at present, the whole family is very satisfied, the refrigeration is fast, not to mention, the noise is really small almost inaudible, too quiet.

If the compressor of the external machine does not work, the internal machine works, then the blowing is the natural wind, according to the situation you said, the compressor may not work, the compressor does not work for several reasons, such as the voltage is too low, the temperature sensor is open, the external fins are dirty, the freon is too much, the compressor itself is damaged, the compressor capacitance is bad, the external fan is bad, etc., the visual detection data is then to find the cause of the failure, if the internal machine does not even have wind, it means that it is a problem with the power supply, check the communication line on the internal control panel, and detect the motherboard. Check if there is any disconnection wire, etc. If the air conditioner is not cooled due to the blockage of the condenser of the outdoor unit or the filter of the internal unit, it is easy to solve the situation. Just clean up the blockage by hand.

In fact, the air conditioner should be cleaned every once in a while to achieve a good cooling effect and protect personal health. There have been many articles on how to clean and clean air conditioners before China Warranty Network, and you can check them one by one. If you are troublesome, you can also directly log on to the China warranty network to find the relevant cleaning and maintenance air conditioning company, and let the professionals help you solve it.

It should be that the compressor capacitor is broken, and only the fan rotates on the external unit, but the compressor does not rotate. First see if the remote control settings are correct, and then look: if the external machine also turns, the eight achievements are leaking freon, find a professional to repair it, take a thermometer and put it at the air outlet to try it, if the temperature is the same as the room temperature, then please master it!

Lack of fluorine, bad press, bad four-way valve, bad circuit board ==

The air conditioner refrigeration is normal, and the heating does not start.

Hello dear! The reasons why the air conditioner refrigeration is normal and the heating does not start are as follows:1

The heating of some air conditioners may not start because of the air conditioner itself, and the refrigerant inside the air conditioner is insufficient. The key to cooling and heating in the air conditioner itself is the refrigerant. Insufficient refrigerant grades can seriously affect the heat exchange of the air conditioner itself.

At the same time, the heating of the air conditioner does not start, and there is another reason, that is, the four-way valve of the air conditioner. The key to switching the air conditioner back and forth for cooling and heating is the four-way valve string. Sometimes it can cause some of the refrigerant mold that would have been used for heating to stare back into the return pipe.

This buried sample cannot meet the heating conditions due to insufficient refrigerant. 2.Dust accumulation in the filter due to inadequate cleaning The heating of the air conditioner may not start because the service life of the air conditioner itself is too long, but there are also reasons why the air conditioner is not cleaned properly.

The long-term cleaning is not in place, resulting in a lot of dust accumulation in the filter of the air conditioner, resulting in a lot of dust accumulation in the internal emergency of the air conditioner itself and the external unit. The heat generated by the air conditioner itself cannot be output normally. 3.

The external ambient temperature is too low, resulting in the failure of the air conditioner and the reduction of efficiency The heating of the air conditioner does not start, and sometimes, it is not only due to the internal reasons of the air conditioner itself but also some factors of the external environment. Because when the external use environment is too low, it will have a certain impact on the operation of the air conditioner itself. There are some air conditioners that only have some basic functions of their own, and the most basic air conditioners of this kind should reach zero or 5 in the use environment.

If the temperature is too low, there will be many failures in the air conditioner, and sometimes the work efficiency will be particularly low, and the start and operation of the air conditioner will also have some difficulties.

Summary. Hello dear, The heating of the air conditioner does not start, it may be that the refrigerant inside the air conditioner is insufficient, the refrigerant is the key to the cooling and heating of the air conditioner, and the grade is insufficient, which will lead to a decrease in the heat exchange efficiency inside the air conditioner, which will lead to insufficient heating. This kind of failure may also occur in the four-way valve of the air conditioner, the air conditioner switches the cooling and heating state through the four-way valve, if the four-way valve is in the air, it will cause some of the refrigerant originally used for heating to return to the return pipe, so that the refrigerant for heating is not enough to meet the heat target that needs to be generated.

The air conditioner refrigeration is normal, and the heating does not start.

Hello dear, The heating of the air conditioner does not start, it may be that the refrigerant inside the air conditioner is insufficient, the refrigerant is the key to the rapid adjustment of refrigeration and heating in the air, and the level is insufficient, which will lead to a decrease in the heat exchange efficiency inside the air conditioner, which will lead to insufficient heating. This kind of failure may also be the four-way valve of the air conditioner, the air conditioner switches the cooling and heating state through the four-way valve, if the four-way valve is air-flowing, it will cause some of the refrigerant that was originally used to make the ants to stare at the stuffiness and heat back to the return pipe, so that the refrigerant for heating at one time is not enough to meet the heat target that needs to be generated.

Extended information: The heating of the air conditioner may not start because the air conditioner has been used for a long time, but the cleaning is not in place, and the filter has accumulated a lot of dust, which leads to the blockage of the internal and external pipes of the air conditioner, which hinders the circulation of air and the heat generated by the air conditioner cannot be brought out by the air, which is a problem that the air conditioner is not usually maintained. The frequent use of air conditioning in Zao Town is generally in summer and winter, and generally after these two seasons, air conditioning will not be used often, and it will be left alone, but this practice is not correct, and a large area of cleaning and maintenance should be carried out after this period of use.

Summary. Hello dear, I am happy to answer for you, the air conditioner does not make a hot air blower and does not turn because the filter screen is blocked, lack of fluorine, voltage instability is caused, which needs to be for different problems, different maintenance, the specific solutions are as follows: 1. When the air conditioner is heating, the internal machine can not be vented immediately, you need to wait for 3 5 minutes, and the external unit can only be vented after it starts to work.

2. If there is no air for a long time, it may be that the filter has not been cleaned for a long time, and the dust causes blockage. At this time, it is necessary to clean the filter screen of the inner unit and the condenser of the external unit.

After a power outage. There was no money on the card, there was a power outage.

The money is charged to the air conditioner and the heat is gone.

Nor does it refrigerate. Does the adjuvant compressor have a turn?

You need to check whether the air conditioner indicator light is on, if the indicator light is off, it may be that the circuit at home is tripped, if the indicator light has a display and a dripping sound, then the air conditioner is delayed to start, and the air conditioner will return to normal after a while.

Check that the fuse is burned out, causing the compressor to fail, then the fuse needs to be replaced, in addition to the fuse outdoor capacitance problems, it will also cause the air conditioner to fail to start after the power off. In this case, it is recommended to have a professional repair.

Hello dear, the air conditioner does not make a hot air blower and does not turn; The reason may be that the power supply is suddenly cut off, resulting in the phenomenon that the external unit does not rotate and does not heat, and the solution is to check whether the incoming calls of the indoor unit and the outdoor unit are normal, because the indoor unit and the outdoor unit are connected by AC contactors; The reason may be that the condenser is faulty, the general air conditioner failure is most likely the condenser is damaged, the outdoor condenser also has its own self-protection system, when it is not cleaned regularly, it will start in its own protection system, the solution is to cause unnecessary trouble we try to clean it regularly. The reason may be the failure of the computer board, and the operation of the outdoor unit is controlled through the computer board, so when the outdoor unit is not running, it may also be the fault of the computer board. The solution is to replace it with a new computer board, which is relatively cheap.

The long-term non-maintenance and cleaning of the air conditioner will make the air conditioner not run, in the structure may be the screw and the rotor locking part pulls off, the flat position of the motor and the mating part of the rotor is not in the right position, due to the problem of injection molding process assurance, the plastic parts will have a squeaky sound, the air guide strip and the connecting rod mechanism belong to plastic parts, the transmission performance of the air guide strip, the stepper motor and the connecting rod mechanism structure is affected, which will cause the machine not to run.
