Ice Maker NOT working

My ice maker is not working, for some reason the water is not making it to the freezer part. I have the type of frig that has a water and ice dispenser. Should i change the dual water valve or the ice maker??
HELP!!! summer time is almost here and we got thru ice ALOT!!

Thank you

Try swapping the wires on the dual water inlet valve. Then try the water dispenser. The water should go to the ice maker. This will tell you weather or not the ice maker valve is working and if the line is clear.
