Icemaker making no ice!

I have this problem for some time now…i change the pump that didnt help…so i dont know what could be the problem. I want to change the whole complete icemaker assembly. Please answer me if i should do that or if you have a clue how to fix it.

Chances are your water valve was ok, either youricemaker isn’t working or the water line(fill tub is frozen)
