## Discrepancy

ROUGHLY A MINUTE AFTER LEVELING AT FL410 WE RECEIVED A DOOR PAX OPEN RED CAS MESSAGE. WE STARTED OUR DECENT AND AROUND FL380 THE MESSAGE WENT AWAY. WE LEVELED OFF. HOWEVER, THE MESSAGE RETURNED AND WE CONTINUED OUR DECENT. THE MESSAGE AGAIN WENT AWAY AND WE LEVELED AT FL200.   REPLACED DOOR SWITCH HARNESS. OPS CHECK GOOD. IAW EMB-505 AMM 52-71-20.
