## Discrepancy

DURING RUNUP, AIR CONDITIONER STARTED MAKING A VERY LOUD BUZZING NOISE WITH BITS OF PLASTIC AND DEBRIS COMING OUT OF THE VENT. THIS WAS ALSO ACCOMPANIED BY A SLIGHT BURNING ODOR AND THE AIR CONDITIONER EVENTUALLY QUIT BLOWING COLD.  INSPECTION OF SYS FOUND THAT THE RT FWD EVAPORATOR FAN HAD DISINTEGRATED.  BURNING SMELL AND PLASTIC DEBRIS WAS FROM THE EVAPORATOR HOUSING BEING RUBBED BY THE FAN.  LOSS OF COLD AIR WAS DUE TO THE FAN NOT MOVING AIR PAST THE EVAPORATOR.  FAN WAS REPLACED AND SYSTEM OPS CHECKED OK.
