## Discrepancy

AIR CONDITIONING SYSTEM WOULD NOT COOL.  RECOVERED FREON AND PERFORMED FUNCTIONAL TEST ON BINARY PRESSURE SWITCH.  SWITCH WAS FOUND TO REMAIN IN AN "OPEN" CONDITION.  REMOVED AND REPLACED SWITCH.  SERVICED FREON AND PERFORMED SATISFACTORY FUNCTIONAL AND LEAK TEST.  AIRCRAFT RETURNED TO SERVICE.
