Treadmill randomly stops, a hazard when running. I have replaced the motor at the company’s expense and replaced the controller at my expense. The control panel is over 1/2 of the price of the entire machine and I believe it to be the cause of the problem. The Nordictarck T6.5 S will randomly stop, some times it won’t stop for several days, then it will stop. Again it is at random. There was no injury but it is a dangerous treadmill, I can only use it to walk, no running.
