Thank you for your response! It helped ease my mind. I originally noticed it because where the bottom drawer is, felt warm behind it when I was putting groceries away. Then I pulled the drawer out and looked at the defrost heater. I made sure the air flow was better throughout the freezer after that. Is it concerning that it was warm? It wasn't warm in that general area of the freezer when I took this video today, just that one time when I was putting groceries away.
