## Discrepancy

FLIGHT 1756, CMH TO PHL - ON CLIMB THRU FL200 THERE WAS A STRONG SMELL OF SMOKE IN THE CABIN.  PACK NR 1 SUBSEQUENT FAILED, SMOKE SMELL DISSIPATED AFTER SELECTED OFF.  MAINTENANCE FOUND AMBER X ON EICAS PAGE.  TRIED TO OPERATE PACK NR 1, PACK FAILED AGAIN WITH SMOKE SMELL IN CABIN.  RELEASED PACK NR 1 PER MEL.  PACK NR 1 SWITCH IS OFF,  A/C IS OK FOR SERVICE.  REMOVED AND REPLACED NR 1 AIR CYCLE MACHINE.  OPERATIONAL CHECK IS GOOD PER AMM 21-51-00, THIS CLEARS MEL.
