Every once in a while, I hear noises from the top freezer part. I
assumed that it was ice cubes dropping into the collection tray. I put
an empty tray under the cube maker but nothing appears in it after the
rattling sound.

There is a handle that when raised is supposed to stop the ice maker
function. Even when up, I still hear the sound.

Suggestions?
