Nope. :-(
He's taking out parts of it and taking it to a parts place and having each part tested. When he finds what doesn't work, he'll be able to replace it, it's just taking him a while...because he only takes one part out at a time.
And he's also working on his thesis! So it's mostly a time issue.
You're much more patient than I am. I'd go nuts without my oven!
Though...I lived for four years in Germany cooking mostly with a microwave, so I guess it's possible to make due. But I don't miss those days!
