## Discrepancy

SMOKE ALARM CHIME ACTIVATED FOR SEVERAL MINUTES IN AFT GALLEY.  NO SMOKE COULD BE OBSERVED VISUALLY OR ORALLY.  AFTER TURNING THE A3 CHILLER OFF ALARM STOPPED AS WELL.  OPERATED A3 CHILLER AND FAULT LIGHT NEVER CAME ON.  DURING FURTHER INSPECTION FOUND WHISTLING SOUND TO BE COMING FROM  CHILLER CART AIR FLAP.  CHILLER OPS CHECK GOOD.
