What's wrong with my Treadmill?

I haven't used my treadmill in a while. I tried to use it the other day and it wouldn't start. I took the cover off and found a diagram that explains a combination of LEDs that is suposed to help you diagnose the problem. All of the lights check out okay, but still it doesn't work. Does that mean it is the motor? Or do you think that the lights would tell you if it is the motor or maybe that has nothing to do with the electrical. I really don't want to replace the motor. I was hoping it could be something else!
