Narrative:
While taxiing for departure, the electric smoke light illuminated. We started performing the electric smoke checklist when the flight attendant notified me of smoke in the cabin. I then ordered the evacuate/evacuation of the aircraft. All of the passenger deplaned the aircraft through the main cabin door without injury or further incident. I believe the problem was due to an open pack valve. The turbo cooling fan was deferred, which provides pack ram air on the ground. The pack may be used in the air, and when it was deselected on landing, the pack valve did not close. This allowed bleed air into the pack causing it to overheat.

Narrative: WHILE TAXIING FOR DEP, THE ELECTRIC SMOKE LIGHT ILLUMINATED. WE STARTED PERFORMING THE ELECTRIC SMOKE CHKLIST WHEN THE FLT ATTENDANT NOTIFIED ME OF SMOKE IN THE CABIN. I THEN ORDERED THE EVAC OF THE ACFT. ALL OF THE PAX DEPLANED THE ACFT THROUGH THE MAIN CABIN DOOR WITHOUT INJURY OR FURTHER INCIDENT. I BELIEVE THE PROB WAS DUE TO AN OPEN PACK VALVE. THE TURBO COOLING FAN WAS DEFERRED, WHICH PROVIDES PACK RAM AIR ON THE GND. THE PACK MAY BE USED IN THE AIR, AND WHEN IT WAS DESELECTED ON LNDG, THE PACK VALVE DID NOT CLOSE. THIS ALLOWED BLEED AIR INTO THE PACK CAUSING IT TO OVERHEAT.
