Electromagnetic clutch fails to engage properly, slips, or is damaged. Inspect the clutch solenoid coil and readjust the clutch clearance according to specifications. Severe wear of compressor bearings leads to bearing looseness. Replace the compressor bearings. Internal components or assembly of the compressor is damaged. Replace the damaged internal parts or the entire assembly. Refrigerant is either overcharged or insufficient. Discharge excess refrigerant if overfilled. For insufficient refrigerant, identify the leakage cause, repair it, and then recharge the refrigerant. Compressor refrigeration oil level is too low. Add compressor refrigeration oil.
