## Discrepancy

AFTER TAKEOFF FROM MSP, CABIN TEMPERATURE WAS 150 DEGREES AND ACCOMPANIED BY SMOKE AND FUMES.  THE RIGHT SIDE AUTOMATIC CABIN TEMPERATURE CONTROL VALVE WAS AT FULL HOT.  FLIGHT CREW DISABLED AUTO TEMPERATURE CONTROL SYSTEM PER MAINTENANCE CONTROL AND CONTINUED MEL 21-03A.  AIRCRAFT RETURNED TO MSP WITHOUT INCIDENT.  MAINTENANCE REPLACED THE RIGHT AUTO TEMPERATURE CONTROLLER.  OPERATIONAL CHECK GOOD AND REMOVED FROM MEL.  AIRCRAFT RETURNED TO SERVICE.
