Reebok RX100 won't work right

Try lubricating the belt. My treadmill requires lubricant every now and then. Its not your treadmill but a treadmill is a treadmill. That's what stops the belt from slowing down due to friction. Go to your nearest Gym they may be able to sell you a tube of lubricant. Good Luck

reebok 8000es incline keeps going up and down and will not stop or go into any other mode

There could be 3 different problems with this machine.
1) loose drive belt (this model has a spring loaded idler that tightens the tension)
2) Bad front drive roller (you wil hear the pulley spinning freely on the front roller if the roller is bad)
3)Last is possibly the walk belt itself. May need to be tightened or replaced.
To try to tighten the walk belt, go to the end of the walk belt and find the 2 adjust allan screws in the end and tighten them 2 revolutions clockwise on both screws.
Hope this helps a little. Tim

You need to replace the walking belt.

If everything still works but no belt movement, you motor controller is more than likely shot. If replacing you want to also pay attention to the deck and belt. Sence it sut down while running, it sound it an over heating problem which is usually caused from too much friction between the walking belt and the deck(the board under it) May require lube or may need replacing.
