The fire broke out around 6:30 a.m. at the mall on the 4400 block of the Black Horse Pike in Hamilton Township.
Officials say the fire may have started inside of the Hollister clothing store on the first floor of the mall and smoke could be seen throughout the building.
The fire inspector believes a faulty light ignited inside of a cabinet burning a stack of magazines and a register.
Officials say the fire triggered the sprinkler system inside the store which quickly extinguished the flames.
The fire was contained to the Hollister store which has been closed due to the water damage. The Hamilton Mall has been opened for business.
The fire remains under investigation.
