Fixing the fridge

What a difference in our food spoilage. My husband was so sick of the freezer burn on our food  from freezing it. He had found out after searching online that there could be problems in the freezer itself. So he took it apart cleaned the whole thing to make sure the air flow was proper for circulation. Put it all back together now there's such an amazing difference. It was all to do with the air flow tube that had frozen in the back behind the inside wall.
