How to Solve Compressor Abnormal Noise?
2 Answers
Solutions for compressor abnormal noise are: 1. Inspect and repair the clutch solenoid valve coil, and readjust the clutch clearance according to specifications; 2. Replace the compressor bearing; 3. Replace internally damaged components or the entire compressor assembly; 4. Discharge excess refrigerant or identify and resolve refrigerant leakage causes; 5. Add compressor refrigeration oil. The functions of a compressor include: 1. Compressing gas as power source and for controlling instruments and automation devices; 2. Compressing gas for refrigeration and gas separation—gas is liquefied through compression, cooling, and expansion for artificial refrigeration; 3. Compressing gas for synthesis and polymerization in chemical industries, where certain gases under increased pressure facilitate synthesis and polymerization; 4. Pipeline transportation and bottling of gases.
My car's compressor has been making a constant buzzing noise lately, like a drum, and it's really noisy when driving. I checked it myself first to see if the belt was tight, adjusted it with a wrench, and found that the belt was a bit cracked, probably due to aging from not being replaced for too long. Then I checked the pulley, which seemed to have a lot of grease buildup, so I cleaned it and added some lubricant, but the noise didn’t completely stop. Later, I realized the internal bearings of the compressor might be worn out and needed replacement. I took it to a repair shop, and after checking with a pressure gauge, the mechanic said the refrigerant was fine but the compressor was faulty. It cost a few hundred bucks to fix. I recommend not ignoring such unusual noises—if the compressor fails, the AC won’t cool, especially in the scorching summer heat. During regular maintenance, have the technician check the belt and the cooling system to save big money.
