Nordictrack treadmill C2100 belk is not slipping motor stops when you step on treadmill at low speeds, step back off and it starts working

sounds like a MCB problem, I have MCB's in stock ready for shipment, [email protected]

Mybe the belt is to lose see if you can ajust the tension of the Belt also to ake sure that it runs straight.

If it stops but you can still hear the motor running then I would check the belt tension. The force of you running could be causing the belt to stop but no the drive.

Unplug it completely, and wait a couple of mins, try again, if still no response you may have a main circuit board fault.

Usually if a belt slips off the pulleys, it's because of misalignment.
The belt is not tracking true, pulling to one side.

do you hear the motor running but the belt is not? if it is the belt need tightened or the drive belt may have broken. remove the motor hood to inspect

I have a NordicTrack C2155. Incline not working. There is a schematic inside. There are red, white, & black wires from the circuit board to the incline motor. Unplug the treadmill and have a licensed electrician construct a flying lead cord with a male spade on neutral and female spade plug on hot. Connect neutral to white and hot to where either red or black were connected. Plug in to see if the motor runs. Careful to remove power when the incline reaches its limit and reverse direction. If the motor runs in both directions, the motor is good. Follow the black two conductor wire to the circuit board and unplug from board. Check continuity across this switch. Run motor and this should toggle off and on. If all this checks out then the problem must be with the circuit board. On my treadmill, the schematic says that +5v should supply the sensor, but I only get +3.3v, which is TTL level. The drive motor sensor supply is +5v. The incline motor doesn't even show a sign of trying to run. Either the output transistor is burnt out or the low voltage caused an error so that it does not try to run the motor. Either way, I'm quite certain that a new controller board will remedy the problem.

if it really is the walking belt that is slipping keep tightening the adjustment screws till the belt will not slip when you try to stop it ( set speed to about 3 and then with your foot try to stop belt from spinning - you should be able to make the motor and whole machine come to a stop ) make sure it is really walk belt spinning and it isnt the motor belt slipping. (if it is motor belt slipping when you try to do the stop the belt trick i just described you will see the walk belt and front roller stop but still hear the motor turning) once you get walk belt tight enough so it doesnt slip then you can worry about keeping the belt centered.

let me know if you need more help on this and let me know how the stop the belt test went

good luck!

One or three things. Either the belt is slipping, needs replacement,or needs tension adjustments or motor cannot turn with a load.
