Jon for Model Number TBX21MAXBRWW I am getting cool air in the freezer but not freezing and the refrigerator portion is roughly room temperature. I've cleaned underneath the refrigerator and uncertain on what to do. The Refrigerator worked until a month or so ago. I'm not certain on what to test and what measurements I should get on each part and if it should be unplugged. Just help if you can.
