Second, if there is problem for the light perception on the furnance door, there will have mistake when calculate the glass length, then the glass will hit the furnance door when entered into the furnance, and all the glass surface will be scratched transversal. Third, to check if there is glass fragments left on the air grid in the cooling part, the glass fragments will cause the scratches easily if it is left on the air grid.
