## Discrepancy

AC AIR SEEMED TO BE PUTTING OUT AMBIENT OAT. 10 MINUTES LATER THE VENT DUCT AIR STOPPED BLOWING AIR. I NOTICED CB HAD POPPED (TEMP CB). I PUSHED BACK IN AND POPPED AGAIN. I TURNED CABIN CONTROLLER FROM AUTO TO OFF. PUSHED CB BACK IN AND FAN STARTED WORKING (VENT BLOWER ON HIGH). I TRIED A/C IN AUTO ON GROUND ON CB POPPED AGAIN.
