## Discrepancy

THE FLIGHT CREW REPORTED THAT THE COCKPIT TEMP CONTROL SYSTEM WOULD NOT WARM WHEN TURNED FULLY HOT. ONLY BLOWS COLD AIR. THE MAINTENANCE TEAM FOUND THE COCKPIT TEMP CONTROL VALVE WAS DEFECTIVE AND WAS REPLACED WITH A NEW VALVE. OPS CHECKS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
