## Discrepancy

DCA - FLIGHT ATTENDANT REPORTED A SMALL AMOUNT OF FUMES IN AFT GALLEY.  TURNED OFF GALLEY POWER AND FUMES STOPPED.  LATER ON, FLIGHT ATTENDANTS REPORTED SMELL RETURNED.  SHUT OFF RECIRCULATION FANS AND PLACED PACK SWITCHES ON HIGH.  SMELL STOPPED AND DID NOT RETURN.  MAINTENANCE REMOVED AND REPLACED THE CABIN RECIRCULATION FAN PER MM 21-21-22 AND FILTER PER MM 21-21-23.  OPERATIONAL CHECK GOOD.
