We've got a Kenmore Elite side-by-side. Have noticed an area of rust on the sheet metal cover for the back of fridge. It's on the right when you look at the back, about half way up. That is, behind the freezer section. The rusty spot is a few inches long and is sometimes damp.
My thought is maybe part of the freon loop is close to the back in that area and is causing condensation on the sheet metal.
Could anybody confirm that or suggest what else might be going on?
