## Discrepancy

LEFT PACK LIGHT ILLUMINATED ON DEPARTURE. FOLLOWED QRH PROCEDURE, WOULD NOT RESET.  PACK LIGHT WENT OUT AFTER APPROX 20 MIN.   PERFORMED FIM TASK 21-62, TASK 801 ON LT PACK TEMP CONTROLLER.  OPS CHECKED GOOD.  LIGHT STAYS EXTINGUISHED AT THIS TIME.  NO HISTORY ON LT PACK CONTROLLER FOR 60 DAYS.  ACFT OK FOR SERVICE.
