I have a sidebyside freezer/refrig with icemakerand water dispenser on the outside of the freezer door. icemaker still crushes ice but doesnt form ice. I suspect its not getting water. i wonder if its not the "solenoid", i.e. the water inlet valve kit part#4389177 that is the culprit since it was the cause of the water dispenser to stop last year which i replaced no problem. Am I on the right track? any help is appreciated, raymand.
