Water leaking from refrigerator

First, I moved the refrigerator out from the wall, unplugged from the electrical outlet, disconnected the copper tubing to the refrigerator, removed screws holding the cardboard backing, removed the nuts holding the assembly to the refrigerator and pulled it out. At that point, I disconnected the tubing units and wiring connectors from the assembly one by one attaching to the new assembly as I went.

However, this was not possible in the case of two wiring connectors. Evidently, the replacement part was made differently than the original. I had to rewire the replacement part as it allowed and then put the reconnected assembly back in place. I then placed the cardboard panel and reattached the copper tubing. Everything is working and no more leaks!
