## Discrepancy

EN ROUTE, THE MAIN CABIN DOOR LIGHT CAME ON, NO PRESSURIZATION WAS LOST.  FLIGHT 4295 THEN DIVERTED TO CVG.  MAINTENANCE INSPECTED AND CLEANED THE MAIN CABIN DOOR PROXI SWITCH THEN ADJUSTED THE MAIN CABIN DOOR PROXI SENSOR IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 52-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
