Maytag Refrigerator Parts Replacement Question

Background:
Refrigerator/freezer stopped cooling, and I heard clicking noise every several minutes. The overload/relay kit was completely fried (almost melted).

Question:
The connections to the overload/relay kit are black from the meltdown but appear in fine shape. I would feel more comfortable replacing those, but am confused on the parts since there isn’t a clear picture on the parts list.
Overload/relay kit part is: [AP4069288](http://www.appliancepartspros.com/part_details.aspx?part_id=4009244"]AP4009244[/URL]

What other parts do I need?

I assume the wire harness ([URL="http://www.appliancepartspros.com/part_details.aspx?part_id=4069288)). (assuming that is the one with blue/orange to fan, electrical outlet connection, and blue/orange to overload/relay kit).

The other white/orange into the overload/relay kit is connected to a small box on the side of the refrigerator. Is there a replacement cable for that?

The simple answer might be just replace the overload/relay switch because the other cables should be fine. However, I want to make sure that it is safe and that the cables, by default, shouldn’t have to be replaced when the overload/relay kit melts down.

Thanks for your help.
