I have a Kenmore stove that's probably from either 2006 or the 90s some time; and we recently replaced all the drip pans in it; I don't know why or who, but one family members pulled a pipe out of the bottom of the back left range and lost the pipe; it's the only range that has this; however the pipe went down through a hole and into the stove.

Now that the pipe is gone, it has exposed a bunch of insulation, and the insulation has fallen into the stove.

I'm unsure how to proceed, I don't know what the pipe is called or anything here is a photo of the issue.
