How weird is this: for whatever reason(s), the oven is working again of its own accord. 23 was about to order a replacement thermal fuse when 15 announced that the range's digital clock is functioning again. We've been carefully testing the oven with short baking tasks and, well... Yay! Best guess is that a mouse got zapped and temporarily shorted out the oven. If that was the issue, the mouse's end was swifter and less painful than if Diego had gotten to it first.
