I read the post by Gene on 6-6-2010, regarding swapping wires for the solenoids that feed the water dispenser, and also for the ice maker. When I did this test, activating the water dispenser did activate the solenoid for the ice maker water fill line, which mean the water inlet valve/solenoid assembly is working properly. Looks like now the problem is upstream from there. What other tests can I do to determine what is causing this problem of not having water going into the ice maker?
