Twice!

I posted in Appliances too but thought this may get a little more traffic here.

This is a brand new range, only 1 month old. I made the mistake of cooking a turkey this weekend without an oven bag and it popped and splattered all over my new oven. So I wiped it down as best I could, washed it out with dish soap and water then wiped all that down. Then 409 to degrease then wiped that down again to remove all the chemicals. Then self clean. All was well until about an hour into it when I heard a loud pop like a light bulb broke. Initially I thought that's what it was but no bulbs were out. Then it happened again and a spark came out the bottom of the oven. I turned off the self cleaning mode and am just waiting for it to cool down.
I will call Wolf in the morning but this can't be normal, right? Any idea what that could be?
