## Discrepancy

THE VAPOR CYCLE AC SYS WAS INOPERATIVE.  TROUBLESHOOTING FOUND THE AC COMPRESSOR DRIVE MOTOR HAD OVERHEATED BY EVIDENCE OF PEELING PAINT ON UNIT.  THIS DRIVE MOTOR WAS INSTALLED A MONTH & A HALF PRIOR & FAILED WITH 55 HOURS OF OPERATION.  THE DRIVE MOTOR PN 1134104-5 SN 490 WAS REMOVED FROM SERVICE & AN OVERHAULED UNIT INSTALLED.  FUNCTIONAL CHECKS OK.
