## Discrepancy

DURING CRUISE, CREW NOTICED A LIGHT TO MODERATE ELECTRICAL ODOR IN CABIN GALLEY AFTER USING THE MICROWAVE (NO SMELL IN COCKPIT).
CHECK LIST FOLLOWED, UNSCHEDULED LANDING PERFORMED WITHOUT INCIDENT.
MAINTENANCE EVALUATION COULD NOT DUPLICATE ELECTRICAL ODOR, HOWEVER DISCOVERED ONE WIRE PULLED OUT OF TERMINAL BLOCK TWO P/N 72757-1 CONNECTOR, ASSOCIATED WITH ELECTRICAL BOX FOR MICROWAVE.  WIRE WAS RE-CONNECTED, ALL GALLEY EQUIPMENT WAS OPERATED FOR 90 MINUTES WITHOUT ANY ISSUES.  OPERATIONAL CHECK FLIGHT WAS PERFORMED WITHOUT ANY ISSUES OR OCCURRENCE OF ELECTRICAL ODOR.
