The air supply, freezer return, and control panel retainers are a single piece foamed in transition that 

connects the freezer to the fresh food section. This transition allows forced air to be directed from the freezer 

to the fresh food section and back to the freezer through the return.  The return also is used for removing 

water after a defrost cycle, which drains into the control panel drain trough and out of the drain tube outlet. 

The retaining clips also help secure the control panel to the ceiling of the fresh food section.
