Ice maker is making ice, but won't eject the cubes. I have read several trouble-shooting tips & tried several things. I've removed the unit, unclogged it, clean & dried it, reinstalled & reset it. The ejector arm/teeth make a rotation & the tray fills w/the appropriate amount of water & then freezes the cubes- all the while I have a solid green light. Once the cubes are frozen & it's time for the ejection/harvest, the teeth dig into te ice, but it's like they're frozen solid & it's not able to pop them out. It tries for awhile, I hear a quick buzz once every 3sec while it tries, but eventually gives up- thinkng it's clogged & then the green light blinks constantly. HELP!
