Treadmill belt will not start...I know this is a common question but hear me out!
We have a Spirit xt185 that has been collecting dust until now. When you plug it in and power the unit up everything is as it should be. Incline is fine, display is normal... etc. When you hit Start it does its usual beeps and countdown but the belt never begins to turn. I have replaced the lower board (First had the board rebuilt, then tried 2 new replacement boards), and also a new motor. Still nothing. The people at Spirit will no longer answer my calls or emails. I am not sure if they are just busy or have no idea what is causing this. Regardless it is pretty sad customer service to say the least. I have lubed the belt and even tried starting the motor with no tension on the drive belt to see if it would at least spin. The only way it will spin is when I hook the motor leads to a battery. I am fairly handy but this one really has me stumped. Any ideas of what I might be missing?
