GE Monogram ZISS480DMCS Ice Maker Problem

The water solenoid valve should have 120v going to it. (You will need a multimeter to chk this). You will need to also chk. for proper ground when verifying the 120v. If you get 120v on each of the pin clips, then your plug is not properly grounded, which means that you need a new ice maker circuit board. This is located in the in dispenser (front panel opens).

Check and make sure that the float arm in the ice bin is down and able to swing. This arm should be down until the bin is full of ice which would raise the arm and stop any water flow until ice cubes are removed, and allows the arm to drop again to start the cycle all over again, to replace the ice that was used. The arm has a spot to snap in and be held where it would be in a position all the way raised, to allow the bin to come out for cleaning or all of the ice removal from the bin, such as to dump the ice in a cooler. The arm should be gently pulled down to hang freely and will slowly raise on its own as the bin fills with ice.
