## Discrepancy

LAS - AIR TURN BACK - FLT 837 - DURING CLIMB-OUT CREW RECEIVED NR 1 PACK FAULT WITH THE NR 2 PACK BEING DEFERRED.  CREW CYCLED THE NR 1 PACK SWITCH TWICE WITH NO HELP.  CREW DECIDED TO RETURN TO LAS.  REPORTED THAT ON DOWN WIND, TIRED THE NR 1 PACK AGAIN AND IT WORKED.  AIRCRAFT LANDED IN LAS WITHOUT FURTHER EVENT.  MAINTENANCE OPS CHECKED THE NR 1 PACK, OPERATIONAL CHECKS WERE GOOD ON THE NR 1 PACK WITH NO FAULTS BEING FOUND.  THERE WAS NO PREVIOUS HISTORY ON THIS PACK.  MAINTENANCE CLEARED THE DEFERRAL ON THE NR 2 PACK BY REPLACING THE BYPASS VALVE IAW AIRBUS 319 AMM 21-61-53-400-001.  OPS CHECK WAS GOOD.
