Yesterday my ice maker quite making ice. It does not appear that any water is even getting to the ice maker, however, the water dispenser works fine. The temperature in the freezer and refrigerator seems fine. Usually, if the ice maker isn't making ice, I'll find an ice cube stuck between the ejector and the arm-stripper, but not this time- it's empty. I've changed the filter and I don't notice any kinks in any of the water lines. What next steps should I take?
