I have a true 400 series treadmill. Everything on it works except the belt will not start. I can move it manually but that's it. Does that mean the motor is bad? (incline motor works and all readouts and lights.)
Did you end up having it fixed? same thing just happened to my ct5.0 horizon treadmill...

Inside the motor there is a pulley, with use over time, that loosens. I have had that problem twice so far, on my third. Sears can generally fix it for about $100. I watched the repair guy do it last time, but it was a while ago, and I forgot what he did exactly.
