## Discrepancy

THE FLIGHT CREW REPORTED THE FREON COMPRESSOR CIRCUIT BREAKER TRIPPED TWICE. THE CORRECTIVE ACTION WAS DEFERRED PER MEL 21-50-01. THE MAINTENANCE VENDOR THEN FOUND THE AC MOTOR WAS FAULTY. THE MOTOR WAS REMOVED AND REPLACED WITH AN OVERHAULED UNIT. OPS CHECKS WERE FOUND SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
