## Discrepancy

MAINTENANCE FOUND THE CABIN DUCT TEMP SENSOR TO BE FAULTY.  THE RESULT OF THIS SENSOR FAILURE WOULD CAUSE THE SYSTEM TO GO AND STAY AT FULL HOT.  MAINTENANCE REMOVED AND REPLACED THE CABIN DUCT TEMP SENSOR.  TEMPERATURE CONTROL SYSTEM FUNCTIONAL CHECKED GOOD.  NO PRESENCE OF HAZE OR ODOR DURING THE CHECK.  AIRCRAFT WAS RELEASED FOR A FUNCTIONAL CHECK FLIGHT AND THE FLIGHT WAS FOUND TO BE SATISFACTORY.  AIRCRAFT WAS RETURNED TO SERVICE
