Uhhhhh!!! I don't think you could use the old board for all LG french door style refrigerators. Mostly because of programs and wire connectors. Best to create a temporary fuse set up where you could just snap on top of the old blown fuse to check the refrigerator for operation like what I have pictured. The purple wire tie serves to hold the 2 fuse holders together and acts as a handle to pull the fuse holder out when I'm done testing.
Or you could just use alligator clips and connect them to a inline fuse holders as well.
