## Discrepancy

AIRCRAFT WAS GROUNDED:  AT ARMING FOR DEPARTURE FLIGHT ATTENDANT NOTED AN AMBER FLASHING CAUTION FOR CHECK DOOR PRESSURE. LIGHT AND CAUTION WENT OUT WITHIN 2 MINUTES WITH NO CREW ACTION.  FLIGHT ATTENDANT ADVISED AT CRUISE THAT LIGHT/CAUTION HAD RETURNED WITH L1 DOOR BOTTLE GAUGE IN THE YELLOW BAND AS WELL. MAINTENANCE FOUND WIRE 23735540-24 BROKEN 6 INCHES FROM THE CONNECTOR BY THE DOOR ACTUATOR AND REPAIRED THE WIRE AWM 23-73-56 (AALA202404047006). MAINTENANCE ALSO REPLACED THE L1 DOOR DAMPER AND EMERGENCY OPERATION CYCLINDER PER AMM 52-11-14 (AALA202404041139). A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPISHED.
