No, chips are of no concern, other than vanity. What conecerns me as a technician is the possibility that one of the thermal limiters on the burners may have failed, contributing to the fire. The temp controls to each burner also need to be tested to see if they are shutting off the current at the proper level. All this is something you cannot do by yourself. Since the product was basically free, all you need to invest right now is a service call by a trustworthy local repairperson.
