Our Jenn-Air freezer-on-top model makes loud noises that sound like something is knocking inside. Also at least the left side is hot to the touch. The freezer seems alright, but the fridge sometimes freezes things in the drawers, like lunchmeat and cheese and most other things seem almost too cold. It's almost on the lowest setting and it still happens. We're not exactly sure how old it is because it came with the house that we bought last year, but it seems a bit worn in it's appearance, although not terrible.
