I Agree with everyone, switch-tree. I had a unit that would go in the up direction from bottom landing, about 4 feet, stop, and then come back down to bottom landing in levelling speed. I was perplexed, every once in a while, it would run ok. Found a Pinched wire shorting to ground on the cover of one of the switch tree switches. I love the DMC's. This is one of the very few flaws in that system in my opinion.
