What is this small screw used for? I am trying to repair the door hinge to keep the door from falling off of the microwave.
Answer Hello Mary,
From the looks on the parts explosion, this screw is used to mount a brace from rear to front on the body of the unit. If the hinges are bent too far apart from one another you can use a small pair of needle nosed vice grip pliers to bend them closer. You do need to have the unit checked with a survey meter afterwards to insure no microwaves can escape the cooking compartment and cause harm to you and yours. If the hinges are close enough, you may have a defective door part that either isn't assembled correctly or something in the door could be broken.
