Narrative

WHILE ENRTE FROM BTM TO SLC ON ACR FLT XXX; WE GOT A PAX OUTER DOOR CAUTION MESSAGE ABOUT OVER THE TOP OF DILLON; MT. WE FOLLOWED THE QRH PROC AND HAD THE FLT ATTENDANT PULL ON CTR HANDLE; AT WHICH TIME WE GOT A RED WARNING MESSAGE WHICH WENT OUT AFTER A FEW SECONDS; BUT AMBER MESSAGE REMAINED; SO WE DIVERTED TO ZZZ WITHOUT INCIDENT. UPON LNDG AND ROLLOUT; ALL MESSAGES WENT OUT. THE GND CREW SAID THE HANDLE WAS FULLY LATCHED WHEN WE GOT TO THE GATE AND IT WAS WORKING NORMALLY. I THEN SPOKE TO DISPATCH AND TOLD THEM THE MAIN CABIN DOOR WAS WORKING NORMALLY AND I HAD NOTHING TO WRITE UP ON THE DOOR FOR MAINT CTL; AS ALL MESSAGES HAD GONE OUT. THE DISPATCHER SAID HE WOULD NOTIFY MAINT CTL OF THIS AND FLOW US THROUGH TO SLC. I ASKED IF ALL OUR PAPERWORK WAS STILL GOOD; AND HE SAID THAT ALL OF OUR PAPERWORK WAS GOOD AND THAT WE DIDN'T NEED A NEW RELEASE OR MANIFEST AND THAT HE WOULD FLOW US THROUGH TO SLC AS FLT #XXXA. WE CHANGED THE TIMES ON THE MANIFEST TO INCLUDE THE DIVERT TO ZZZ; AND CONTINUED ON TO SLC WITHOUT INCIDENT.
