remove the front plastic cover on the icemaker and you will see a bunch of little holes make a jumper wire out #10 or 12 house wire strip about 1/4 inch off the ends an insert in the holes marked t&h this will start a test cycle make sure you hold the plastic insulation so you don't get bit if the ice maker starts cycling remove the wire and watch for it to stop listen for the icemaker valve to open if the ice maker finishes and the valve didn’t fill replace the water valves if the icemaker doesnt cycle and you may have to kind of twist the jumper back and forth to get it to make contact depending on the gauge you used then replace the ice maker motor module if you hear the valve open and the ice maker doesnt fill check for a frozen ice fill tube that should do it
