A:

You could have a problem with the power board again. I posted a wiring diagram for that treadmill in the first image below. The second image shows a troubleshooting flow chart for that problem that you are having with the incline. You may be able to use that information to diagnose and repair this problem if you want to fix it yourself. Note: Use extreme caution when checking live voltage as described in that second image. Wear electrical safety gloves and safety goggles when measuring that live voltage. Unplug the treadmill as soon as live voltage testing is completed .

You can order parts from this page: NordicTrack C1800 Treadmill Model NTL99020 Parts . Be sure that you unplug the treadmill before accessing internal components and replacing parts.

The part number for that power board is 181220 (Key 26 in that parts drawing) in case you need that component.

I hope that this information helps. If you need more assistance, reply with additional details.

If you get to the point where you need to have a service technician diagnose and repair this failure, you can schedule service through this link: Sears Home Services .

Q:

How do I remove the existing pulley and flywheel on a treadmill motor and reinstall on new motor?

A:

The pulley and flywheel screw on to the motor shaft. To remove the pulley and flywheel, hold the motor shaft and turn the pulley clockwise to remove.

It is easier to remove the pulley when the motor is mounted to the base in the treadmill. A strap wrench is the easiest way to turn the flywheel after you have the motor shaft secured.
