## Discrepancy

DURING CRUISE, AN ELECTRICAL BURNING SMELL EMITTED IN THE CABIN AND FLIGHT DECK.  TURNED OFF CABIN VIDEO AND FOLLOWED COM PROCEDURES FOR ELECTRICAL SMOKE AND REMOVED POWER TO THE RECIRCULATION AND GASPER FANS.  SMELL DISSIPATED AND AIRCRAFT CONTINUED TO DESTINATION AND LANDED WITHOUT INCIDENT.  REPLACED THE POTABLE WATER COMPRESSOR AND PRESSURE SWITCH.  OPERATIONAL CHECK GOOD.
