Hi, my oven door had one loose screw on the left hinge; It was difficult to tighten this screw partly because it was installed crooked. Holding the spring loaded hinge in place and trying to tighten the screw was hard to do. At home, I have a two foot long phillips screw driver which makes it easier to do. Now because the screw was installed crooked from the factory the screw hole was partially stripped and wasn't going to hold. I drilled another screw hole right above the hinge mounting plate and added a second screw which over lapped the plate. So far so good. I wanted to install a speed nut, or nut plate behind the sheet metal, but the only way to get one in there would be to remove the stove completely.
I also thought about drilling a 3/16" hole through the hinge and stove for a pop rivet. Right now it's holding so I will leave it alone until it fails again, if it ever does.
