I wanted to close this thread by offering my own feedback on what I discovered on this down draft hood. Grease had splattered on the assembly that rises out of the counter top and once cleaned with some Awesome from the 99 store the hood operated perfectly. It was only dirty, but it was sticky enough to cause it to stutter and drag, and the sensor thought it was hitting something and kept taking it down, and up, and repeating. cleaning it solved the problem. Yes, the grease was mostly on one side making it look as though there was a problem with the track...
