Why does my whirlpool ice maker make ice, quit for several weeks, then start again?
Refrigerator ice makers are designed to stop when the ice holding receptacle is full. How often do you dispense ice? Are you sure the ice maker has stopped when the receptacle is not full? There is usually some sort of arm that gets raised as the receptacle fills up and when it is high enough, it shuts off the ice maker. Check to see if that arm is working properly.
