## Discrepancy

ABOUT 30 MILES FROM PHL AIRPORT AT 9,000 FEET, AN ODD SMELL STARTED.  FLIGHT ATTENDANT THEN CALLED US & ASKED IF WE SMELL SOMETHING.  WE THEN USED OXYGEN FOR REMAINDER OF FLIGHT & AT GATE NOTED AMBER FAN INDICATION ON COND PAGE.  SUSPECT CIRCULATING FAN AS PROBLEM.  REPLACED CABIN RECIRCULATION FAN 1 & OPERATIONS CHECKED OK IAW AMM 21-21-51.
