Will damage to the car air conditioner compressor cause abnormal sound

　　Will damage to the car air conditioner compressor cause abnormal noise of the air conditioner? The answer is yes.

　　As an important part of the car, the air conditioner belongs to one of many mechanical parts. After informal use or neglect of maintenance, the air-conditioning system does have the possibility of abnormal noise, but the fault often appears in the models after 4 years of use, and there is no need to worry about new cars.

　　Filter element/pipe clogged

　　If the air conditioning pipeline is blocked, the internal pressure of the compressor will be too high and abnormal noise will be produced. Due to the special location of the compressor, it is difficult for users to find abnormal noise in the initial stage of abnormal noise. When the abnormal noise gradually becomes louder, it proves that the service life of the compressor has been affected. At this time, the compressor and other components should be repaired immediately.

　　In addition, if the air-conditioning filter element contains foreign matter, it will also cause abnormal noise, but there is no need to worry about this kind of situation, because the abnormal noise can be improved by replacing the air-conditioning filter element.

　　The electromagnetic clutch is damaged

　　Since the electromagnetic clutch is installed close to the ground, the electromagnetic clutch will be stained with dirty things such as sewage or mud after the vehicle drives over the watery road. If it is not cleaned up in time at the initial stage, the inner bearing inside the electromagnetic clutch may be damaged in the future, which may cause abnormal noise.

　　In addition, as the vehicle has been used for longer and longer periods of time, the loosening of the transmission belt of the air-conditioning compressor is also one of the reasons for the abnormal noise. In addition, the air conditioner compressor is highly dependent on the electromagnetic clutch during operation. If the transmission belt becomes loose, the working load of the electromagnetic clutch will increase. This can easily cause damage to the electromagnetic clutch, and even directly cause damage to the air conditioner compressor.

　　Generator damage

　　As mentioned above, the electromagnetic clutch of the air-conditioning compressor will be repeatedly engaged during working hours. If the power of the generator is insufficient, it will cause abnormal noise when the compressor is working.

　　Lack of lubrication for air conditioner compressor

　　If there is a lack of lubricating oil inside the air-conditioning compressor, the compressor will produce abnormal noises similar to metal collisions under long-term friction. At this time, the air-conditioning compressor needs to be maintained to avoid complete damage to the compressor due to lack of lubrication.

　　In addition to the above several reasons, if an abnormal sound similar to water flows in the glove box when the air conditioner is turned on, it proves that the expansion valve of the air conditioner is working, and the abnormal sound will disappear after a period of time. This kind of situation is normal. Car owners don’t need to worry. The abnormal sound of the air-conditioning system is basically caused by the aging of the air-conditioning system or the negligence of maintenance. This type of situation is different from that the air-conditioning is not cool, because the abnormal sound of the air-conditioning system will affect the service life of the compressor. At this time, you should go to the relevant store for inspection and maintenance as soon as possible to avoid more serious damage to the compressor.
