I removed the screws inside the oven door and the retainer rings holding the handle onto the glass. I then replaced the handle put on new retainer rings and used the new screws provided and re-attached the handle and glass to the door. Total fix time 10 minutes. I was impressed by the quick delivery of my new handle and the fact that they sent new hardware as well. My oven was only down for three and a half days , only because it happened on the weekend.
