open the freezer and remove the food, check the back panel and see if theres any frost on the back panel at all, look real good and let me know, thanks Bryan
Yes, there is frost on the back panel.
I removed the back panel but cannot locate the part(s) described. There is only one panel (lower) to remove. The coils run underneath and parallel with the floor.
I have two photos of the area and will attach them to the reply email.
