Harman XXV Wire ? Probe ? Who knows ?

I hope someone can help with this.

Inside the Harman XXV on the left side is a wire with a round end on it. Very small. Can someone please tell me what this is and hopefully its not important.

Thanks.

Not sure how to post pic.

If you were to stand in front of the stove and open the door this "wire" which is not an electrical wire would be located on the left side against the triangular folds of the stove. To me it looks like a wire left by mig welder.

Anyway I was cleaning the stove and this "wire" just fell off when I touched it. The stove is fuctioning fine with no blinking lights or unusual sounds.

Any help would be great.

Thanks.

Anyone ??
