## Discrepancy

THE WHEEL WELL FIRE LIGHT ILLUMINATED WITH THE LANDING GEAR RETRACTED AFTER TAKEOFF FROM IAH.  THE AIRCRAFT WAS RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND NO EVIDENCE OF FIRE.  THE OVERHEAT DETECTION UNIT WAS REMOVED AND REPLACED AND OPERATIONAL CHECKS WERE GOOD.
