Sihaiwang: I believe that everyone in life will find a problem when using air conditioning. That is, after the air conditioner is turned off, the air conditioner does not stop working directly. Everyone thinks that after the air conditioner is turned off, it should stop blowing immediately. However, some careful users find that Changhong air conditioner will still have a phenomenon of blowing after it is turned off. What's the matter?
Why does Changhong air conditioner still air after shutdown
After the air conditioner is turned off, the air will still be out. If the air is out for only a few minutes, it is normal. Because the air conditioner has many functions now, it may need to be dried and mildew proof after turning off. It needs to wait for a while before turning off. If the air conditioner is still blowing, it's not likely at all, unless you don't turn it off at all, or the remote control fails, or the internal control system of the air conditioner has problems. If you can't turn it off for a long time, you need to find maintenance personnel.
What's the matter with the air outlet closed when the air conditioner is on
If this phenomenon occurs in winter, it should be that the air conditioner is heating and defrosting, when heating, the external machine works, and the air outlet of the internal machine will be closed, at this time, it will not supply air to the room. Why? Because the temperature of the outdoor unit is too low in winter, the machines on the surface of the outdoor unit may be frosted, which may affect the heating of the air conditioner, so a temperature sensor will be installed on the surface of the outdoor unit. When the outdoor temperature is lower than how many degrees, the air conditioner will defrost automatically, and the defrosting time will not supply air. It needs to wait until the defrosting is over, which is the setting of the air conditioning system.

Causes of automatic shutdown after air conditioning is turned on
1. The temperature sensor of indoor unit may be damaged. Open the shell of the indoor unit, and there is a 3-4cm long copper sleeve on the inner copper tube coil, in which is the pipe temperature sensing head. You can buy it in the air conditioner repair shop, usually a few yuan.
2. The outdoor unit is installed in the grid, or there is something blocking around the air outlet of the air conditioner, resulting in poor ventilation, then the air conditioner will cause protection shutdown.
3. It is also possible that the starting capacitance of the cooling fan of the outdoor unit is damaged, resulting in the fan not running. This is because the temperature is too high, the protection shutdown will occur. It can be observed with the naked eye. When the fan does not turn, the starting capacitance of the fan needs to be replaced.
4. When the refrigerant leaks, the cooling capacity of the air conditioner will be greatly reduced, and the air conditioner is easy to overheat. The air conditioner with refrigerant leakage will make a lot more noise than before, which is very easy to identify. Only need to find a master to add fluorine, and check where there is leakage of fluorine.
