The ice maker has been acting up in my RF4287HA.
The water line is open, it fills the tray just fine.The problem is that the machine constantly tries to harvest the ice. My google-fu brought me to this link: http://www.justanswer.com/appliance/7i7qv-samasung-fridge-model-rf4287hars-xaa-ice-maker-not-making.html From that link, I can confirm that my ejector blades are stuck in the 3 o clock position with the arm up.
When I reset the ice maker as per samsung's instructions, the tray fills up with water. So, no water line issues. However, the end result is that the ice maker makes a complete wheel of frozen ice, with the ejector blades frozen inside. I broke one section out to get a better look.
The link above says to simply replace it, but I am not sure if the problem is in the unit, or with another module buried in the fridge. Any help would be appreciated.
