And, when I was referencing an ac fan pointed up, the placement is outside the rig behind the bottom vent, not inside the rig directly behind the frig. Heat from the cooling unit goes out thru the outside vents, less heat venting out means hotter frig operation. You likely have fans installed at the top vent, double check to make sure they are running, four on our domestic and loud when they kick in.
