I'm hoping that someone can help.

We have a very high pitch sound, somewhere in our kitchen that we can not
find. We even shut off the electricity to the whole house to see if we could

I am absolutely stumped.

This thread saved my sanity - I don't own a meat thermometer so I was able to rule that out right away - turned out to be an overhead light bulb that was on its way out, which someone else suggested here as a potential cause. As soon as I flipped off the lights - voila! Blessed quiet. Thank you!
