Thanks for a comprehensive teardown, and here because I'm thinking of making a new control board for the Leovit. One thing, the article seems to fall short on one crucial point though, given that it's about replacing the motor, and that's where to get a replacement and details about the motor itself. Being pedantic, it also doesn't actually describe how to replace the motor, only how to get to the stage of being able to replace it.
