Real easy fix- 30 to 45 minutes. Remove the door from the stove and lay on a blanket as not to damage the door. Using a Phillips screwdriver, remove the outer door trim and panel to gain access. Once inside remove the screws and brackets holding the middle glass. Then remove the screws that hold the metal insert that holds your inner glass and replace it. I recommend using a screwdriver and not a drill driver as to not over torque and possibly break any glass. Remember there are no gaskets around the glass pieces so be careful and reassemble in reverse order. Take pictures as you disassemble if you are not sure of yourself to put your mind to ease during reassembly! 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
