Ice maker stopped working

Hello
Ice maker diagnostics .
1) Do you have 1/2 inch of water across the tray of the ice maker ?
2) If so and the water is frozen, do you have 0-5 degrees in the freezer section? The ice maker thermostat will not let the ice maker harvest unless you have temperatures of +10 degrees or colder.
3) Have you tried manually cycling the ice maker ? If not see the technician link below.
