Noise While Operating A/C System: Notes

DESCRIPTION 
  • Noise from magnetic clutch, A/C compressor, hose or refrigerant line
POSSIBLE CAUSE 
  • Magnetic clutch operation noise
  • A/C compressor vane noise
  • A/C compressor slippage noise
  • Hose or refrigerant line interference noise

* If there is gas leakage, air enters the A/C system. The desiccant within the receiver/drier absorbs the moisture from the air and becomes saturated. If the A/C system is used in this condition, the inside of the A/C compressor will begin to rust due to this moisture, which may cause lock up or noise to occur. Therefore, replacement of the receiver/drier is necessary.
