## Discrepancy

AT CRUISE THE FLIGHT ATTENDANTS REPORTED SMOKE SMELL AND HAZE IN THE MID CABIN.  CREW COMPLIED WITH THE QRH AND TURNED OFF CERTAIN COMPONENTS AND CIRCUIT BREAKERS.  SMOKE GENERATION STOPPED AND DECREASED.  FLIGHT LANDED WITHOUT FURTHER INCIDENTS.  GSO MAINTENANCE FOUND RECIRCULATION FAN  TRIPPING ITS CIRCUIT BREAKER AND PLACED THE SYSTEM ON MEL.  ATL MAINTENANCE REPLACED CABIN RECIRCULATION FAN AND RELAY R2-59 PER THE AMM.  RECIRCULATION FAN CHECKS GOOD AND MCO/PLAC REMOVED.
