## Discrepancy

DURING PREFLIGHT WITH THE APU BLEED IN NORMAL, ACM FAN MADE A LOUD NOISE, NOTICED A BURNING ODOR IN CABIN,  CABIN SUPPLY TEMP STARTED IN 130'S AND CLIMBED TO 180'S BEFORE BLEED TURNED OFF.   IN MAX MODE,  FAN NOISE NOT AS BAD BUT STILL HIGH SUPPLY TEMP AND ODOR.  WITH APU BLEED OFF AND NR 2 ENGINE ON, NO LOUD FAN NOISE BUT HIGH SUPPLY TEMP AND ODOR WITH LITTLE TO NO FLOW OF AIR.   REMOVED ACM.   INSTALLED OVERHAULED ACM, ALL WORK PERTORMED IAW MM 21-51-00.  INSTALLED ACM TO WATER SEPARATOR DUCT AND OPS CHECKED IAW MM 21-51-00.  OPS CHECKED GOOD.
