Unit is not making ice

              Unit is not making ice. Unit has flex tray ice maker, could not locate any harvest button for the ice maker. The display was not working on front of door, fixed damaged wiring to get display running (On off switch for ice maker on display, display was not functioning for years),    After this worked, was looking for fault codes on main display based on tech manual, none showed. Put unit in to test mode, would not show any error codes on front display. Based on tech manual, the control has blinking lights on ice maker module part of PCB, there was no blinking lights that indicated any problems with ice maker. Followed tech manual to OHM check motor, switch & thermistor based on temp guide from UI, all checks out fine. Ohm’d out the water valve, this checks out fine, water pressure through front is great. Is there any way to cycle this ice maker? Or a way to activated water valve perhaps by switching the inlet wires and pressing for water?  Thanks in advance
