Kitchenaid KSSS48QMX00 ice maker not working

[lou123]

Kitchenaid freezer stopped making ice and a repair tech came out and replaced the ice maker.  Still no ice.  The water dispenser works fine.  Also, the ice maker optic control boards were replaced.  Anyone have a step by step procedure that I can use to diagnose this?  I suspect it might be the water supply valve but did not want to keep throwing parts at it like the previous tech did.  Thanks
