Replace Water Dispenser Reservoir

The GE refrigerator’s motherboard went bad, which caused the fan in the refrigerator to stop working, which then caused the water tank in the refrigerator to freeze up. It now has a leak and needs to be replaced.

How difficult is this to do. I have located the part (#WR17X11440), which has hoses that run to the back of the unit, I’m assuming. Before I get into replacing the $20 part, is this a fairly easy task?

Appreciate any expert advise on this.

Actually from the tank, one line runs to the freezer door, and the other runs to the water valve.
