I first removed the unit and used two screws to reconstruct and stabilize. When it cracked again, I re-stabilized by inserting a spacer between the top of the right end and the top of the cabinet. This stopped any upward movement of right end during the tray emptying function. That worked, but the tray was still not emptying completely. I removed the tray and cleaned calcium deposits from each cube cups. This finally solve all problem, but eventually I was moved to replace the unit with a new 14 cup tray, which although a bit of a hassle to replace, the smaller cubes definitely dispense much better.
