## Discrepancy

FLIGHT CREW REPORTED THAT DURING PREFLIGHT CHECKS THE MAIN CABIN ENTRY DOOR UNLOCK LIGHT WOULD NOT EXTINGUISH. THE MAINTENANCE TEAM TROUBLESHOT AND DETERMINED THAT THE DOOR VENT SOLENOID WAS DEFECTIVE. THE DEFECTIVE SOLENOID WAS REMOVED AND REPLACED WITH A NEW SOLENOID. RIGGING AND FUNCTIONAL CHECKS WERE PERFORMED SATISFACTORILY, AND THE AIRCRAFT WAS RETURNED TO SERVICE.
