Check to make sure the ice maker is plugged in. you will have to remove the ice bucket, then you will see a white colored wire insulation coming down from the ice maker, and will likely go behind a white colored cover plate, sometimes there is no cover plate, if there is, remove the plate, then check the plug. be careful you don't push it too hard, you might bend the plate that contains the outlet for the ice maker plug. If the green LED still doesnt light up, or if it flashes, you'll need to replace the ice maker. the chances of it being a wiring issue beyond that ice maker outlet are pretty darn slim.
