To initiate the calibration routine, hold down the SPEED +
button and the SPEED - button simultaneously for three seconds. During the calibration routine, the INCLINE
TRAINER will automatically rise to the highest incline level and then return to the lowest incline level.
The incline system may need to be calibrated. To initiate the calibration routine follow the steps below.
Step 1
Place the key into the machine. The key's slot is located on the bottom of the console, below the start and stop buttons.
Step 2
Press any of the incline buttons and then remove the key from the machine while the incline is changing. Pause for a few seconds and then put the key back into the slot.
Step 3
Wait as the treadmill automatically shifts to the highest possible incline and then descends to the lowest level. The treadmill should now be recalibrated.
You must tried again the s.calibration, for easy diagnose, and troubleshooting. However you must Adjust the speed sensor, test it, clean it, and tight any plug or connector, see the diagrams attached and proceed according. 2) Lube the elevation motor, the shaft + gear, test the motor itself for open or short. see the diagram attached. If you machine use RELAIS test it for dirty, or open and repair. God bless you
cleal the contacts relais, and replace if necessary. Of course your LUBE the gear and shaft too.Test the elevation motor for problem bearing for repair.
I had the SAME problem, several time, with my NordicTrack A2250 Treadmill.
Allow it to go fully up and then fully down several times, without turning it off. IT seems to "cycle" that way 3 times and then "reboots" itself and starts working normally, again.
I had to figure this out myself... none of the suggestions I read worked.
1. remove the screws from the bottom of the enclosure case. 2 or 3 in the front and 1 on each side
lay it back down, and power it up, and actuate your incline. watch the end of the motor, to see if the shaft is moving. It probably IS turning but only a little bit. NOT enough. In this case I'd say it is the sensor.
2. Unplug the unit of course.
3. the incline motor is in the middle of the pack,..you'll see a black tube looking thing sticking up.
4. on the bottom side of this, you will see,..or feel for a black square sensor attached to bottom of the motor casing.
5. follow the wires and unplug this.
6. pry it off with a screw driver. Remove incline assembly, if you cannot reach it.
7. replace sensor and try it again.
if the MOTOR does NOT turn when using the incline buttons, the problem backs up to possibly a bad control board. or a bad motor on your incliner, however, i'd say that's the last thing to go.
Order of failure: 1. sensor 2. control board 3. motor.
