We have a Nordic Track c2300. Seems to be an electrical problem.

SOURCE: Calibration Mode for nordic track treadmill model

Hello there, The calibration mode for a nordictrack is as follows.

With the safety key out, hold the stop and speed up arrow at the same time while inserting the key. Release the buttons. You will then be in diagnostics.
You then press the stop button one time.
If you are trying to calibrate the incline you just need to hit the incline up button and the machine will do an incline calibration. The unit should go all the way to the top and return to the bottom when completed.

If you need to calibrate the speed you will need to press and hold the speed up button on the console until the display reads 85. The machine should then be running at its maximum speed (either 10 or 12 mph depending on the unit)
The display will show a speed on the console and should be within .3 of the maximum speed.
If it is not then it will need to be adjusted using a potentiometer on the control pwb.
To access the control pwb open the hood cover. Should be 3 screws in the rear of the cover and 2 screws on the bottom of the unit.
Once inside the cover locate the control pwb. On the control pwb there will be a yellow/orange potentiometer. This is the adjusting part.
Use a non-metallic phillips head screw driver to adjust the potentiometer either clockwise for faster or counterclockwise for slower.
Hope this helps!
Good Luck! Tim

SOURCE: How do you replace the walking platform on the

First, remove the motor hood. There are 3 screws at the front, and 2 underneath. The screws underneath will have to be removed by tipping the treadmill over, or pulling the console towards the rear of the machine.

Next, remove the side rails. This is a little tricky because of the cushion adjusters on each side of the deck. If you look underneath the deck, you will see that the adjusters are on rails that are attached to the platform. Remove all of the screws from the side rail and push it toward the rear of the machine while also moving the adjusters rearward. You'll have to kind of move them together until the adjuster slides off the rail. Do both sides.

Remove the rear roller, by loosening the bolts. Don't mess with the front roller unless you intend to replace the motor belt. You don't need to remove the front roller or the walking belt.

There are 4 bolts holding the deck to the frame. The rear ones go through the frame to a lock nut. The front bolts screw into the isolators. Remove them and the deck will come loose. You can slide it out from the walking belt.

Place the new deck next to the old, and start moving the parts over. Make sure the safety decal is on the bottom like the old deck. All of the holes are pre-drilled except for the belt guides. You'll have to measure for these. Now do everything in reverse to reassemble the machine. I'm also attaching instructions on how to adjust the belt.

There is a belt hidden under the hood that connects the front roller to the motor (motor/drive belt). Start the treadmill at 3 or so and carefully apply pressure to the walking belt until it slips/stops. Watch the front roller. If it continues to spin when the walking belt stops, it’s the walking belt. It the front roller stops with the walking belt, the motor belt is loose and needs adjusted or replaced.

To adjust the walking belt, locate 2 hex head bolts, one on either side of the deck on the very back of the machine. These bolts will be recessed inside the plastic covers. Your treadmill came with a tool for this, but if you can’t find it, a standard (not metric) allen wrench kit will work. It’s helpful to have a wrench in each bolt so that you can adjust them at the same time, but one will work.

The allen bolts thread directly through each side of the rear roller. As you tighten the bolts, it pulls the rear roller away from the front roller, tightening the walking belt. This also centers it; if you tighten one bolt, it pushes the belt towards the center of the walking deck away from the bolt you’re tightening. So if the belt is too far to the right, tighten the right bolt and it will move towards the center.

Place your wrenches in the roller bolts and turn the machine on to 3-4 miles an hour. Keep your fingers clear of the belt, it will eat them. This method is quick, because you can see the belt move as you tighten one side or the other. It takes a few seconds, but if you tighten the right bolt for instance, you will see the belt move to the left. If the belt is loose but centered, tighten each bolt ½ turn and then get on the machine and see if it slips. The user manual will tell you to pull it up a couple of inches to test the tightness, which is a relative method and doesn’t necessarily work. My wife can pull on the belt and get 2 inches, and I can probably get 3 or even 4 if I’m showing off. The best way to test it is to gradually tighten it until you can run on it without it slipping.

You should lube the belt a couple of times a year. You can get them from iconfitness.com

Good Luck!

SOURCE: My nordic track treadmill's walking belt stops

Unplug the unit remove the motor shroud inspect the drive belt if the rubber feel slick then my recommendation is to replace the drive belt. Adjusting the drive belt may take care of the problem if you do not need to adjust it too tight. If you choose to do the adjusting and feel you have adjusted the running belt thinking it would resolve the slipping, then back the tension down until it the running belt is slipping then adjust until the slippage is resolved.

I can't help with the manual. But, if you reach under the area where the readout is, push up on the cord or any of the opening underneath the display will pop out. You should be able to find the battery compartment. The unit uses 2 AA batteries. If you find a manual, let me know.

Thanks.

SOURCE: Nordic Track Ifit Treadmill has power but walking pad not working

If everything on the display console is working correctly then we know it is either a problem with the wires from the console to the controller or the controller itself. In most cases this means you need a new controller. To verify, take off the motor hood and find the green circuit board called the motor controller. With the power on go into manual mode and push the speed up button to a slow speed. If you see an LED light with "spd ctrl" next to it flickering but the belt still does not move then we know the problem is with the controller sending the signal to the walking belt, in which you should check the wires that go to the motor. If they are connected correctly then we know a new controller is in order. If you do not see a flickering light then it means the speed signal never got there and the problem will be with the wires going from the console to the controller. This is called an upright wire harness.
