My treamill works fine until I turn the speed up from 5.5mph to 7mph and over. When it gets to a higher speed the treadmill just cuts out and turns off-and won't come back on for a while. Theres a rubbery smell but thats it. Theres no lights or power at all when this happens.
It's the thermal cutout sitching it off when the motor overloads. You need to buy silicone oil (wd40 in a can) and spray the bottom of the belt to lubricate it. I do this with the treadmill running, mind your fingers though!
