## Discrepancy

THE FLIGHT CREW REPORTED THE ENVIRONMENTAL CONTROLLER WOULD NOT WORK IN AUTO MODE. THE MAINTENANCE TEAM TROUBLESHOT AND DETERMINED THE CABIN TEMP SENSOR FAN WAS DEFECTIVE. A NEW CONDITION FAN WAS INSTALLED. FUNCTIONAL CHECKS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
