## Discrepancy

AN ELECTRICAL SMOKE ODOR WAS DETECTED ON THE FLIGHT DECK AND IN THE VICINITY OF SEAT 3B OVERHEAD. THE UTILITY BUSSES AND RECIRCULATION FANS WERE TURNED OFF AND THE EQUIPMENT COOLING SELECTOR WAS TURNED TO STANDBY IAW CHECKLIST. THE ODOR DISSIPATED AND THE AIRCRAFT LANDED WITHOUT INCIDENT. MAINTENANCE REPLACED THE COOLING AIR FAN AND FAN CONTROL CIRCUIT CARD. OPERATIONAL CHECKS WERE GOOD WITH NO ODORS DETECTED.
