How do I re-calibrate NordicTrack treadmill T9si when distance displayed is too low?

open up the control console and look for loose wires... if no loose wires are found, call CoreCentric Solutions and ask if they refurbish that control board... CoreCentric Solutions Reverse Logistics Core Collection and Recovery...

Please RUN the Software calibration for easy diagnostic and fix it. Read the instruction manual, and follow the steps.

Run please the software calibration, ready your instru manual and follow the steps for diagnostic and fix it.

1) Run the calibration software for easy diagnostic and fix it. go to owner manual, and go under the hood for following the steps.2) Exchange the batteries by new ones, cleanup contact from the batteries for oxide, and see if there are Not SOME WIRES BROKEN OR LOOSE.3) Tight the keypanel from flexible cable vs display board, 4) tigh the display board vs lower board. 5) attached the sensor reed switch by 1/8" or 3 mms adjusted according. 6) Test the main motor controller board for 115 Vca, and then +5 vdc for output coming to display board very important.
7) Test the transformer for primaRY VOLTATE see the tip adjust how to do it. 8)

1) Adjust the reed swithc, see the diagram attached, clean, and tight the connector.
2) Tight the ribbon cable from keypad ,tight the display board connector vs lower board.
3) After you did this, run the software calibration for diagnose, troubleshootign in according with the instruction manual.

sincerely. God bless you

Dear Sir:RUN inmediately the software calibration for easy diagnose and troubleshooting.Proceed according with the instruction manual
adjust the speed sensor, cleand, and tight the connector, may be the s. sensor is faulty.

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 no distance goal was set, this display will show the distance that you have pedaled, in total revolutions. If a distance goal was set, the display will show the distance still to be pedaled during your workout.
