Kenmore 363.9752711 refrig w/ icemaker
replaced supply line and water supply valve (WR57X10033)
Still no water to ice tray.
What should I replace next?

Is the water supply line turned on? If you have a filter, have you checked to see that water will flow through it and it's not clogged? Have you checked the ice maker module? If you have a volt/ohm meter you should be testing the componets before changing out parts
