My RS21 ice tray fills up, freezes then when it opaeetrs and rotates, the ice does not come out of the tray. This results in more water going into the tray and after a while it then spills into the ice bucket compartment, runs into the freezer area and also into the water trip tray so sometimes in the morning the drip tray is full and there is water on the floor. Any idea what it could be?
