Bun with Schnitzel in a Dairy Oven

I placed a bun with a meat schnitzel in a dairy oven where cheesecakes and similar items are baked. The day before, when the schnitzel was placed in the bun, it was hot, so perhaps the bun is considered meaty. The next day, I wanted to heat the bun with the schnitzel and mistakenly placed it in the dairy oven. When I noticed the mistake and removed it, the schnitzel was not very hot yet, but the tray was scorching. What is the status of the oven, the tray, and the rack underneath? I would appreciate an answer, thank you.

Shalom and blessings 

If the schnitzel was not "yad soledet bo" (hot enough to cause a burn), everything remains as it was.
