Oh, definitely under warranty. They're coming Tuesday to repair it. (July 4 is a big holiday here, and falling on a weekend means that a lot of companies (and even more people) take Friday and/or Monday off.)

One of the things a good engineer thinks — and thinks hard — about is How can this fail? And how should it fail? It sure looks like the engineers responsible for this oven (and the GE one we didn't buy) dropped that on the floor. Engineers like to swap stories of engineering failures, whether their own or someone else's; this post was mostly about sharing such a story.
