Nordic. Track incline won't work or calibrate
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.
