It was inside the oven. Saw a spark when the microwave turned on.

Earlier, we had seen a spark when cooking a frozen package of
steamfresh veggies and this had caused the board that is attached on
the interior top of the microwave to be partially torn. Not sure what
the purpose of the board in the interior top part of the microwave is
for.

It's the wave guide cover. It's a sheet of mica that has fractured and
needs replacement.
