Thanks for your help. D, Sorry, but there are no other safe alternatives, For safety sake , you should replace the cooktop assembly(it's all one piece). The glas portion of the cooktop, is a heat resistant temperred safety glass, and there is a possibility of it shatterring, and caving in, when your cooking,and creating more damage to the range and yourself. It's an expensive part, but a somewhat easy repair. Part number: AP4482718
Here are some general, basic instructions from the service manual, Remember to label and mark any wires or components you remove or disconnect. REMOVING AN ELEMENT & LIMITER AND THE COOKTOP GLASS ASSEMBLY CAUTION:
When you work on the electric range, be careful when handling the sheet
metal parts. Sharp edges may be present, and
you can cut yourself if you are not careful.
