Thank you for your question. I know it can be disappointing when the icemaker stops working. A good check for this will be to cycle the icemaker manually and then watch toward the end of the cycle if it will fill with water. To cycle this icemaker, pull the front cover off and you will see a large and small gear. Turn the small gear counterclockwise approx. 1/4 turn and the icemaker should start (see image). Toward the end of the cycle it should fill with water. If it cycles but does not fill and you can hear a humming sound, it means the water valve is being energized. In this case, the valve # 241734301 will probably need to be replaced.
If it cycles and fills, it will indicate that either the icemaker thermostat has failed or the temperature in the freezer is not cold enough (below 12 degrees) to cycle the icemaker. To check the temperature, place a thermometer between some packages. Air temp is
a good check. If it's not cold enough, usually adjust the control to a colder setting will resolve this. If the temperature is ok, I recommend replacing the icemaker # 5304458371. It's more economical then replacing parts. I hope this will help you. If you would like more assistance reply to this thread and I will be glad to assist you further.
