I have a Sears refrigerator with a top freezer which
has an ice maker with a wire lever .The wire lever drops
when the ice is removed and the icemaker releases water
into the ice cube tray.Somehow (maybe visiting kids)
the wire lever was locked into the UP position .
  Before calling a repairman,I decided to check it 
myself.There's a black box over the front end,that 
I found could be easily pulled off.I unscrewed the 
Phillips screw on the center large gear and it pulls
off.Then I started to loosen the three Phillips
screws holding the cover plate and the lever 
snapped back down like it should.
 Everything works fine now.
