Unplug and remove motor cover. Try moving the motor and small belt. Tighten belt a bit. Plug in and Push start. If it fails to start check the carbon brushes of motor for wear/ replace. Try all same again. If it fails to start motor could be burned out.

not for sure but i would look for an access panel and look to see it the drive belt has come off the pulley or if the drive motor has come unplugged.

Your problem is your motor controller is blown out. This happens when you don't replace your walking belt routinely. You'll need a new belt and a new controller. Depending on the model of treadmill you have the parts could range between $250-$400.

most likely cause is a burnt out motor controller, you'll need to replace it.
