I have the Nordictrack C2500, and for the second time the main board double beats when trying to start it. You press a button for speed, incline, the fan, anything and it double beats and won't start. The last time they we called support and she had no idea what was wrong and just sent up a whole new mother board for the treadmill. I can't believe that is the only fix. What is the problem with this machine?

If your Kettler treadmill is not working correctly and you have to press Start and Speed + - to start, and it goes back to a pace of 6km/h after 30 seconds, there could be a few possible causes:

1. Check the control panel: Make sure that the control panel is functioning properly and that the buttons are not jammed or stuck.
2. Check the speed sensor: Make sure that the speed sensor is functioning properly and that it is not blocked or damaged.
3. Check the incline sensor: Make sure that the incline sensor is functioning properly and that it is not blocked or damaged.
4. Check the main board: Make sure that the main board is functioning properly and that it is not damaged or malfunctioning.

The
Steps for Newer Style Console Calibration


1. Locate the calibration area on the
rear or underside of the console (a hole, near the console\'s center, that goes
through to the electronics board. (This hole should not have a screw in
it.)


2. Insert a pencil (eraser end),
into the hole and feel around for the cal button (will click when
pressed).


3. Press the button 2 times
(with the pencil eraser). The first click should show CL11 in the
console, the second click should show CL21.


4. If the process was done correctly,
and CL21 appears in the console, you are in "calibration mode."
The next few steps consists of pressing buttons on the console
and observing settings. This will not require any other tools.


5. Press ENTER. CL22 should display in
the TIME window and (??) in the SPEED window.


6. Press ENTER. CL23 should display in
the TIME window and (??) in the SPEED window.


7. Press ENTER. CL24 should display in
the TIME window and (??) in the SPEED window.


8. Press ENTER. CL25 should
display in the TIME window and (??) in the SPEED window.


9. Press ENTER. CL26 should
display in the TIME window. You should then see the letter
"E."


10.
Press
ENTER. You should see "SS" or "55" in the console.


11.Push the STOP/START button. For safety, at this point, you should step off, or be
off, the treadmill.


12.
Push
the ENTER button. The walking belt should start to move, accelerate to maximum
speed, then stop on its own.


13.
When
the belt stops, the incline should self test by raising to its
highest incline position, then lowering back down to its lowest position.


14.
Once
the incline test is complete, push the POWER button 2 times. The unit should
shut off and the console should go completely blank. If this
happens, the treadmill is done calibrating and is ready for use.


If the letter
"F" appears in the SPEED or INCLINE window when the power button is
pressed 2 times, the treadmill is indicating a failure somewhere
either in the SPEED or INCLINE (depending on the window the
"F" appeared in). Troubleshooting the failure would be the next
step.

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.

The NordicTrack is a treadmill designed for in-home use. It offers a speed range of 0 to 10 mph and an incline range of 0 to 10 percent. It folds up vertically to save space when you aren't working out and can be rolled to a different room. The console has 16 preset workout programs and features iFit interactive technology. If you have problems with the console or walking belt, you can often fix them yourself with some basic troubleshooting steps
Instructions

1. Power Turns Off When You're Using the Treadmill
   • 1 Check the reset switch on the bottom of the treadmill near the power cord. If it has tripped, the top of the switch will protrude. Wait 5 minutes then press the switch.
     
   • 2 Check that the power cord is plugged in completely. If it is plugged in, unplug it, wait 5 minutes then plug it back in.
     
   • 3 Remove the magnetic key from the console then reinsert it.
     
   The Console Won't Turn Off
   • 1 Insert the magnetic key into the console. Your C2500 is stuck in demo mode if the console won't turn off after you remove the magnetic key from the console.
     
   • 2 Hold the "Stop" button down for a few seconds.
     
   • 3 Press the "Speed" down (-) button. Remove the magnetic key.
     
   The Incline Does Not Change Correctly
   • 1 Press and hold the "Stop" and the "Speed" up (+) button. While holding the buttons, insert the key into the console, then release the buttons.
     
   • 2 Press either the "Incline" up or down arrow button. Wait while the incline raises and lowers. This recalibrates the incline system.
     
   • 3 Remove the key from the console.
     
   Walking Belt Slows
   • 1 Unplug your C2500 and remove the key from the console.
     
   • 2 Turn both rear adjustment bolts, located on the back of the walking deck, to the left, a 1/4 turn.
     
   • 3 Lift the edge of the walking belt in the middle of the deck. You should be able to lift it 2 to 3 inches off the walking platform. If the belt is still too tight, loosen the bolts another 1/4 turn each.
     
   • 4 Plug the treadmill in and reinsert the console key. Walk on the belt at a slow speed to see if it still slows. Repeat Step 2 if necessary.

It sounds like you just need some calibration. To calibrate incline, turn power on press press any incline buttons, as the incline try to change unplug the key. Now re-nsert key and incline will self calibrate,

Try this calibration procedure.
Turn the power switch on. Remove the safety key. Hold the Stop and Speed Up or Speed Plus buttons down then insert the safety key.
The display should show some numbers.
Press the stop key one time and the display should show some other numbers and some 00's. Press the Incline Up button and see if the Incline begins to move, if it does let it go all the way up and then all the way down, wait a few seconds after it stops, then hit the stop key 4 times. It should be calibrated. If it didn't move then the board or the incline motor is bad.
