## Discrepancy

CREW DECLARED AN EMERGENCY DUE TO PACKS VALVE 1-2  CLOSED WAS PRESENTED WHILE DEPARTING OUT OF KGUC. AS WE WERE GETTING TO THE RESET OF THE PACKS, WE CROSSED 10,000MSL AND SHORTLY AFTER THE AIRCRAFT GAVE US A WARNING CABIN PRESSURE. WE STOP THE CLIMB. THEN WE RESET THE PACKS AND RAN THE QRH FOR IT, AND AFTER 15 MIN TO 20 MIN THE PRESSURIZATION NORMALIZE. CORR ACTION MX TROUBLESHOT TO BAD CABIN DISTRIBUTION VALVE. MX R&R'D VALVE OPS TEST GOOD.
