If the new ice maker gets no signal, check the basics. Make sure the ice maker's switch is on, and check its fuse on the power board. The ice maker also won't cycle unless the freezer is below about 14°F. If all of that is good, suspect the wiring harness. The 639086 harness has been discontinued with no replacement, so a harness problem usually means repairing the wiring.
