I have just purchased a replacement door handle, however I can’t determine how to get into the door to expose the screws holding the handle on.
You have to remove the inner door frame (choke cover) in order to access the screws. You can find the instructions and the video clip in one of our previous posts: http://forum.appliancepartspros.com/microwave-repair/255-microwave-handle-2.html
