A bad solenoid water valve assembly could be causing this problem. Before buying that part, I recommend that you conduct more diagnosis and troubleshooting. When the ice maker fills, listen to see how long it energizes that water valve solenoid. You should hear a faint buzz when the solenoid is energized. That valve should be getting voltage for about 5 to 7 seconds. If it is apparently only getting voltage for a second or two then you probably have a bad ice maker module. Replacing the ice maker assembly should fix that type of problem. If the solenoid buzzes for the appropriate amount of time, I recommend that you check the water fill tube above the ice maker to see if it is partially frozen. Also, check the water flow from the dispenser if you refrigerator has a water dispenser. If not, then I recommend that you shut off the water supply and remove the waters supply line from the back of the refrigerator. Place then end of that line in a bucket and briefly turn on the water supply to check the water pressure and flow from the supply line. A water pressure or water flow problem could be causing this failure. If the valve gets voltage for 5 to 7 seconds and you find no other cause for low water flow to the ice maker then you will probably need to replace that water valve to fix this problem. You can order that part from the
website. Be sure that you
unplug the refrigerator
before accessing internal components.
If you need more help, reply with additional details and the full model number of your refrigerator.
