Last year I got a used performax 16-32 and have used it a couple of times with no issues. Today I was using it to even up some wood that I had cut for edge banding and the conveyor stopped working. Not sure if I was trying t take too much of a bite. In the past I have had it stop on me and I was able to push a reset button and everything started back up. But today that didn't work and I let it sit for about an hour thinking it may have over heated, but still no change. When I turn on the power, I get a humming noise, but no movement. I admit to not knowing much about motors - any ideas would be appreciated.
