It is unlikely that your refrigerator is holding your ice maker hostage in order to convince you to replace the water filter. However, the issue may be connected. In some refrigerator models, the water line that supplies the ice maker and water dispenser connect through the same water filter. If the filter is clogged, water can’t get through to create ice.
For standard refrigerator maintenance, we recommend cleaning the ice maker every three months and changing the water filter every six months. You stated that this is a fairly new refrigerator. There are situations where routine maintenance will need to be more frequent. If you live in an area with hard water (water with a high concentration of dissolved minerals), your water filter may need to be changed often.
We recommend changing your refrigerator’s water filter and giving the unit a few hours to make new ice. If the ice maker is still not working, you may need the assistance of a home refrigerator repair service.
