I tried to fix the problem of the oven door that would not fully close by installing new hinges, but that would not fix the problem. If you have this problem too, then you will probably have to replace the hinge receptacles. You can check to see if yours need replacing by looking inside them with the door removed. You should see two silver color pins, each about 1/4 inch in diameter, that the hinge plate hangs on. If these are worn, the door will not fully close, even with new hinges.
Replacing the hinge receptacles is a pretty involved job. A do-it-yourselfer can do it, but be prepared for a job that will take several hours.
First, and most importantly, TURN OFF THE ELECTRIC POWER TO THE OVEN.
Second, take off both oven doors.
Third, you will need to take all the trim pieces on the front of the oven as well as the control panel. This will require you to disconnect several electric connectors and plugs (see above about TURNING THE POWER OFF). You may want to make a sketch or take a picture with your cell phone to help remember how to reconnect everything.
Fourth, carefully slide the oven assembly out about 5 or 6 inches. Move both top and bottom ovens as a single unit, DO NOT try to take them apart. The oven is heavy, this may take a helper.
Fifth, once the oven is out away from the wall, you will be able to see the hinge receptacles. You will need a hex driver to remove some of the screws. Replacing the old receptacles may take a little persuasion, be careful you don't bend the oven frame. I recommend you install a shim on the top, forward facing screw hole to force the new hinge receptacles to tip rearward slightly. A 1/4 flat washer works nicely.
Putting everything back together is a reverse of taking it apart. Take your time and double check you have all the electrical connections reconnected properly before you close everything up. Your door should now fit tightly and the light will stay off.
