Ice maker water wont come in and fill up ice tray. when I test the tray to dump it is ok.

Make sure the freezer is at least 17 degrees or colder (colder is better). If you have a square cover on the end of the ice maker see if you can pull it off and press on the gear face (don't turn just press). That may clean the electrical contact springs and get it working again. Basically if ya got water, 17 degrees or colder you will get ice. Other than that the ice maker motor module is likely bad (broken gear, etc.). Pretty common.

SOURCE: Ice Maker Overfills With Water

Ice maker has adjustment on right side of power head. If ice maker is inside on upper left, you can remove white cover from it and the adjusting screw in on right. Turning counter-clockwise will decrease fill by 1/2 to 3/4 of ounce. Sounds like a small amount, but ice make only uses 4 ounces per fill. If this does not fix, try replacing fill valve. If ice maker ice bin is in the freezer door, you have to remove cover to ice maker in the top of freezer. Ice maker is screwed into top of freezer and need to be removed to take off cover to adjuster screw. same procedure for reducing water flow time as above.
