Both the freezer and bottom of refrig too hot

Was very simple once I found out where the defrost timer was located. I had a friend walking me through trying to find the location on the phone. Not all models have them in the same place. Once the part was located all I had to do was remove the cover, unplug the old one and plug the new one in just the way the old one came off. The black wire was easy to locate on the old and just matched it up. Put the cover back on and plugged it in. It was no time till I started feeling it cool. Checked both top and bottom with thermomater and it was where it should be within 12 hours. I am happy and using it again. Was almost ready to throw it out. Did not know it was so cheap to fix one. Nothing anyone can't handle. If this woman can do it anyone can.
