My refrigerator is moaning - sound lasts anywhere from 2 - 20 seconds, pauses for less than 1 second, then resumes for another 2-20 seconds. The sound seems like it's coming from the ice maker, inside the freezer. I set the switch for the ice maker to off and the sound is still going. However, it does seem that something is wrong with the ice maker because two weeks ago I emptied out the ice and it got refilled, but this past weekend I emptied it out and no more ice was produced.

The moaning is a loud sound, seems like it is working very hard all the time. This is the refrigerator I have: http://www.kitchenaid.com/shop/-[KSSC42QVS]-402302/KSSC42QVS/. It would be sort of nice to fix the ice maker, but it's not a have-to-have - if I could just figure out how to stop the moaning, and have no ice, I'd settle for that.

Thanks very much for any assistance!
