## Discrepancy

ON FLIGHT 4060 THE CREW REPORTED THAT THE PACK 2 VALVE CLOSED ON EICAS.  THE CREW RESET PER AOM, PACK 2 VALVE RESET THEN CLOSED AGAIN (PACK 2 VALVE CLOSED).  THIS WAS FOLLOWED BY A BURNING ODOR IN THE COCKPIT, WHICH CLEARED AFTER 3 MINUTES.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  FOUND COUPLING AT DUAL TEMPERATURE CONTROL VALVE BLOWN OUT THAT GOES TO THE HEAT EXCHANGER.  REMOVED AND REPLACED THE COUPLING IAW AMM 21-60-01.  THE OPERATIONAL CHECK WAS GOOD.  NO ODOR NOTED.  THE AIRCRAFT WAS RETURNED TO SERVICE.
