Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! The two most common causes of this issue are main control failure and a problem with the wiring to the door at the door hinge. Unplug the refrigerator and check all connections at the door harness. Leave it unplugged for at least 15 minutes. Any change when plugged back in?

Well I unplugged for about 20 minutes ,unplugged both door switches and continuity both were OK,I find it interesting that the ice maker doesn't light up for ice size but has power coming in . I can remember in the past I could make changes to ice size with door open.What ever happened it was all at once Ice-maker and water threw door Quit at same time.When you push for ice the hopper door opens that is all. Are these systems controlled by relays on main board??

They are, the main control board will likely need to be replaced.

Ordered a new main board ,replaced no change no water threw door and ice maker still doesn't light up to change ice size . can you tell me if ice maker is defective will it prevent water threw door from working ? The 3 harness on top of door are red ,red-white,orange and white-black small wires. The other harness is larger wires they come in BL ,RD,YELLOW,AND BR on the the other side of the harness coming form the door BL, turns to WH the rest are the same.I noted that when the cover is removed for the access to the harness the circulation fan inside stops the door switch is ok I have 12v across RD and RW in the harness that goes to the door controls.Any ideas !
