The ice maker is not making ice. I have checked to see if the water line is working into the water valve and there is. I have checked the supply line from the valve to the ice maker and it's clear, but I don't see or hear the valve sending water into the supply line to fill the ice maker. I have unplugged the ice maker and plugged it back in and moved the arm from stop to activate... I don't hear the ice maker working or moving. I have unplugged the power from the water valve and from the ice maker for as much as 5 minutes, and many times. Is there any way to check to see whether it's the valve or the ice maker that needs to be replaced? What do you recommend? Dave
