Warping in door window

> Probably two separate problems.

I think you're correct, unless it was arcing while cooking.

The warping is not a problem until and unless moisture can get rapped and damage the fine metal mesh / screen inside the door panels.

The lack of heat with a loud noise is usually a shorted high voltage diode or failing magnetron. I would of course focus on getting it to work before I tackled the door trouble.

Assuming yours is a GE JEB1095 as per your posting category, there should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

Here are some links you or someone you know can use for test help, but read their safety warnings first:
