## Discrepancy

AIRCRAFT WAS GROUNDED: ON INITIAL CLIMB OUT, CABIN PRESSURE LIGHT ON 1R DOOR WAS FLASHING PERIODICALLY, AND 1R SLIDE OCCASIONALLY CHANGED FROM ARMED TO DISARMED INDICATIONS ON ECAM DOOR PAGE. LASTED ABOUT 5 MINUTES, THEN HAD NORMAL INDICATIONS THE REST OF THE FLIGHT. MAINTENANCE REPLACED CABIN PRESSURE DETECTION PRESSURE SWITCH 14WN PER AMM 52-73-12. A SATISFACTORY LEAK / OPERATIONAL CHECK WAS ACCOMPLISHED WITH NO ISSUES NOTED.
