## Discrepancy

AIRCRAFT WAS NOT GROUNDED: AFTER ARMING R1 DOOR, ORANGE CAUTION LIGHT FLASHES AT TOP LEFT OF FLIGHT ATTENDANT CONTROL PANEL WITH ORANGE INDICATION AT R1 POSITION ON DOOR/SLIDES INDICATOR. FLIGHT CREW RECYCLED R1 DOOR ARMING MECHANISM. NO HELP. MAINTENANCE FOUND DOOR DAMPER AND EMERGENCY OPERATION CYLINDER PRESSURE IN YELLOW BAND AND SERVICED IT PER AMM 52-10-00 WHICH RESULTED IN CLEARING THE CAUTION LIGHT.
