What does Midea air conditioner display F0 mean? How to solve the problem when Midea air conditioner appears F0
What is the fault of Midea air conditioner F0
Midea air conditioner displays fo to indicate that the refrigerant of air conditioner is leaking.
1. If this problem occurs shortly after installation, it should be that the installation personnel did not install properly in accordance with the specifications. You can find the installation personnel to reinstall.
2. It is also possible that the system detects insufficient pressure due to valve blockage, so it is recommended to clean the valve.
3. It may be that the air conditioner is lack of fluorine. The lack of fluorine may be that the air conditioner has not been filled with fluorine at the beginning. This situation is relatively rare. Generally, the fluorine adding personnel will not have this problem. It is only possible that there is a leakage of fluorine. It may be that there is a leakage in the air conditioner or a certain place of the air conditioner, resulting in the decrease of refrigerant. The maintenance personnel can be asked to check the air tightness of the pipeline and add fluorine to the air conditioner.
4. It may also be that the indoor temperature sensor is faulty. Open the air conditioning panel and check whether the sensor is faulty. If it is damaged, replace the temperature sensor.
5. It may also be that the cooling pipe is cracked. Replace the cooling pipe.
6. If the compressor leaks, fluorine will also leak. Replace the compressor with a new one.
