## Discrepancy

WHILE AT 40000 FEET, TURNED MICROWAVE SWITCH ON FROM COCKPIT.  FIRST OFFICER THEN WENT BACK TO GALLEY & SMELLED BURNING ELECTRICAL ODOR.

TURNED THE MICROWAVE SWITCH OFF IN THE COCKPIT THE ODOR SEEMED TO DISSIPATE.  REMOVED MICROWAVE OVEN, REF CL 350 SMM 25-30-03.  INSPECTED ALL WIRING & COMPONENTS OF MICROWAVE OVEN.
