The GE ice maker is an independent appliance that is installed in the freezer compartment of the refrigerator. The ice maker has three distinct operations, to fill with water, freeze the water and harvest the ice cubes.
If your GE ice maker has stopped producing ice or dumping the ice cubes out or will not fill with water there are replacement parts in most cases for most make and models to repair your ice maker. The water inlet valve, module, ice lever/bale arm, ice maker mold with heater or drive gear. In some cases you can purchase a brand new OEM GE ice maker or an ice maker kit that comes with an ice bucket and water fill valve for just about the same price that it will cost in parts to repair the old ice maker, not to mention your time and labor.
