## Discrepancy

PRESSURIZATION CABIN WOULD NOT PRESSURIZE IN AUTO.  REFERRED TO QRH AND WENT TO MANUAL CONTROL.  IN MANUAL CONTROL RATE SEEMED VERY SLOW, IT TOOK AROUND 2 MINUTES FOR THE CABIN TO START DOWN FROM 5000 FT TO 200 FT.  RETURNED TO PSP. REMOVED AND REPLACED CABIN PRESSURE CONTROLLER WITH A SERVICEABLE UNIT.  OPS CHECK GOOD.
