How to Solve Loud Noise from Car Compressor?

Solutions: First, check whether the air conditioning belt is loose, whether there is oil on the belt, and whether the belt is worn. If there is a problem with the electromagnetic clutch, only the electromagnetic clutch needs to be replaced, not the entire clutch assembly. If the problem persists, contact a maintenance technician for timely inspection to prevent further damage. Causes of abnormal noise from car air conditioning compressor: Electromagnetic clutch: Since the electromagnetic clutch is installed close to the ground, years of driving may cause the electromagnetic clutch to be contaminated with sewage or mud, leading to internal bearing damage and resulting in abnormal noise. Loose drive belt: A loose drive belt of the compressor is also one of the causes of abnormal noise. The car air conditioning compressor has high requirements for the electromagnetic clutch during operation, and a loose drive belt will increase the load on the electromagnetic clutch, which can easily cause damage to the electromagnetic clutch. In severe cases, it may even burn out the compressor. Insufficient power generation: Repeated engagement of the electromagnetic clutch causes insufficient power generation from the generator, resulting in insufficient working voltage for the compressor and thus abnormal noise.
