Just about 2 hours ago we have notice a smell of something burning. It smells like it is coming from behind the refrigerator. The plug socket is not hot. Just the smell is bad!
We have no idea what it is... help... We did pull the refrigerator out earlier this morning, now it it about midnight. Any idea what is going on??

This is something we have no business guessing-on. I would call an electrical contractor. Make sure the power stays off, until you have a professional look at the situation. I believe you made the right decision to seek help!

Keep in touch on what was found.

Thanks... We found out that it was actually the light above the kitchen sink. It wa so hot to the touch. The smell of it was bad!

Happy to hear you have found the problem! I guess it's time to go shopping for a new light fixture. Once it's installed, make sure you monitor the problem.
