LG has water dispensing but no water going to ice maker

Hello
See the service manual link below. I can think of two other possibilities why you are not getting water to the ice maker.
1) If your water inlet tube that supplies water to the ice maker is plugged with ice. That can be caused by your water inlet valve feeding low water pressure to the ice maker causing the tube to freeze up. Now that you have replaced he valve you may have corrected the problem, but the tube is still frozen. You can remove the ice maker and see if it has ice in the tube or shut off the refrigerator for 24 hours with the doors open to defrost all ice from the tube completely.
2) If your tube is not iced up you could have an ice maker that is defective. The ice maker may not be sending power down to the inlet valve. The ice maker normally cycles about every 90 minutes and will open the inlet valve to send water through it for 4-7 seconds.
Hope this helps solve your issue.
