Product review (2 stars): it worked great for a while
Got it in January, it worked great for a while.  Just conked out.  Giving a full ice message with no ice in it.  That is not one of the options in the troubleshooting guide.  I don't see any warranty information with the unit.  I think there might not be one.  Amazon's return policy is only a month.
Oh well.
Previous units I owned came with a one year warranty.

Update, I found the warranty tucked in the manual.  One year.  I'll check back in after I see how this is resolved.
