I made a pizza in my wall oven in a cast-iron skillet at 550 deg. After that, my wall oven went blank. No power. Clock, lights, everything, blank. Normally, I would have called an appliance repair company. But I watched a youtube video and the first one said that many times after baking at high temps, the FUSE would blow. Replacement seemed fairly straightforward, 8 screws and the fuse was front and center. I ordered a new fuse from AppliancePartsPros.com and it was in my mailbox in a couple of days. Followed the video and IT WORKED. Thanks AppliancePartsPros.com. Saved me a bundle
