How to Solve the Abnormal Noise of Air Conditioning Compressor?

[Freddie]

There are many reasons for the failure of the car air conditioning compressor, such as compressor jamming, bearing damage, lack of lubricating oil, etc., which can all lead to abnormal noise from the air conditioning compressor. Generally, when these faults occur, it is not recommended to solve them by yourself. It is advisable to go to an auto repair shop for inspection. More details are as follows: 1. During the working process of the air conditioning compressor, compressor jamming is a common phenomenon. The main reason for jamming is poor lubrication. When there is a frequent lack of lubricating oil, it needs to be taken seriously because it may cause severe abnormal noise inside the compressor and even lead to wear and scrapping of the compressor. In such cases, it is necessary to check whether the clutch is slipping or if there is an issue with the transmission belt. 2. The compressor often operates under high load, shifting from low speed to high speed, so the requirements for the electromagnetic clutch are very high. Moreover, the installation position of the electromagnetic clutch is generally close to the ground and often exposed to rain and mud. When the bearing inside the electromagnetic clutch is damaged, abnormal noise will occur. At this time, it is necessary to check the air conditioning belt, whether the installation screws are loose, whether the belt is oily, and whether the belt is worn. If there is a problem with the electromagnetic clutch, only the electromagnetic clutch needs to be replaced, and the entire clutch assembly does not need to be replaced. 3. The compressor requires reliable lubrication during operation. When the compressor lacks lubricating oil or the lubricating oil is used improperly, severe abnormal noise will occur inside the compressor, and it may even cause wear and scrapping of the compressor. It is recommended to report for repair in time, otherwise the noise will become increasingly louder.
