Some repair / testing tips to verify this is the part you need:
Some tools you will need depending on the model will be a multi-meter for power testing, 1/4" nut driver, 5/16" nut driver, phillips head screwdriver, channellock, 3" jumper wire stripped on both ends a 1/4", and possibly 3/8" - 7/16" wrenches. Once again the tools you may need depends on the model your working you'll figure it out.
1st thing you need to do is look inside the water chute that channels the water into the ice maker tray. If you see ice build up the that is your problem. You will need to remove the fill chute from the refrigerator and runs hot water through it to clear it out. This usually happens for one of three reasons. Either the fill valve coil is sticking open after the ice maker is done calling for water, you have the freeezer set to cold of a temperature, or the thermostat is not regulating the temperature correctly.
2nd thing you will want to do is shut off the water coming in to the refrigerator fill valve. Now remove the fill hose from the fill valve. Have a small bucket or tub available to catch water. Now turn the water on and let it pour into the buckiet. If your water pressure is strong running into the bucket you can move on to the next step. If it's not real strong and running out very slowly then you will need to determine why it's not getting good pressure. The ice maker is set on a timer. During the harvest cycle, after the ice is slightly heated, and pushed into the ice bucket it will have about 4 seconds to fill the ice maker tray again. If your pressure coming in is not good then the pre-determined time it has to fill is not sufficient, minus water pressure, to fill the ice maker tray.
3rd, make sure you have the back panel removed so you have access to the fill valve power wires. Remove the wires from the fill valve coil that has a water line running up to the ice maker's water chute, stick a probe into each of the power wires, get your jumper wire out, remove the cover from the ice maker, put one side of the jumper wire into the hole labeled N, and the other into the hole labeled M. Here you are manually jumping neutral to motor. As soon as you've inserted the wires into the holes the gear should start moving (if it doesn't then replace the ice maker 2198597) and you will see a spark inside the gear. Once you see the spark then you can remove the wire and go to your multi-meter and watch for 120vac to be sent to the fill valve. This will take a couple minutes for the ice maker to send power. If you never see power to the fill valve replace the ice maker it is not sending power as it should during the cycle. If you do get power, have done all of the first steps, and are getting no ice then replace the fill valve that your refrigerator requires.
If you've done all of these steps correctly then you should have determined what the problem is and you'll have ice again in no time.
