GE Refigerator ice maker is not working? It does not make ice, so I assume water is not getting to the maker.?

checked the filter(s)? checked to make sure the line isn't frozen? lot of possibilities but we need more info. then google the model number along with your question and likely someone else has already figured it out. the user manual has troubleshooting steps as well. most are free online

More than likely the fill solenoid is defective. It will look something like this and can be found where the water enters the refrigerator.
