I need to replace the handle on my GE microwave. There are two screws on the top of the handle and two on the bottom of the handle found on the inside of the door. I can get to the 2 screws I can see but there are 2 more (one on top and one on the bottom) that is hidden by the metal casing just inside the door. Does any one no how to access the other two screws hidden by the metal casing? I thought about cutting a small piece out of that metal casing with a dremel tool, since it would not be seen after I install the plastic lining back on the interior side. Has anyone else had this issue?
