This is the second time of needing repair. I remove the ice bucket, open the crusher, remove the 5 blades. Straighten the blades, reinstall. I then order new blades, The next time it happens I will install the new blades. The reason for the malfunction, (my guess), two ice cubes partially melted stick together and the size and angel the enter crusher cause the problem. I don't see it as the crusher problem or the blades being to weak. The ice container gets over full, opening and closing the main door lets in warm air. We plan on emptying the container more often to stop over filling. [The time it took was caused by researching the how to on YouTube, taking photos before taking each section apart, paying attention to small details of unimportant parts when taking pictures.] I'm the ultimate unskilled do it your self er.
