I have an older (8+ years) Sub Zero that stopped making ice
yesterday. Until now I've never had a problem with the unit.

Yesterday morning I heard the unit making a mild grinding/rumbling
sound, coming from the vicinity of the ice maker. I remove the ice
bucket and pushed the control lever up and then back down and the
noise stopped. Dumped the old ice in the sink and returned the bucket
to it place.

Since then, no ice, and the (very few) items in the freezer started to
thaw (they may have started thawing before I noticed the problem).

Defrosting may do the trick if a piece of ice jammed the mechanism. Ice
makers are the biggest singe problem with refrigerators. Easy to replace
though.
