Nordic track C3000 treadmill no red LED light on control board going nowhere very slowly

You should have a speed arrow up & down, this increases and decreases the speed in .1 mph. Try this control and see how the unit re-acts if the speed does not adjust in .1 mph increments or it stay the same either way it sounds like an upper board issue. Go to go to customer service the replacement parts put you M# and will give part# and pricing.

Got beeping? I JUST figured out how to fix it. Take the console apart and pull the connector from the back of the iFit card adapter. Plug back in, should be good as new!

I know it's been months, but, if you still have this problem try this: 1. remove the philips screws holding the motor/belt/electronics cover on: you can lay the whole thing on it's side and remove them from the bottom. there's two in the front and two on the sides.
2. Obviously, unplug the unit! before doing anything. lay the unit back on it's feet (normal position)
3. Find the incline motor assembly. it will be int he middle of everything. black tube thingy.
4. take a cordless drill with a flat head screw driver bit, and turn the incline motor CCW. until the bed is flat.
5. what what I have read, you should shop for a new incline sensor. these fail before the motor does.

If everything on the display console is working correctly then we know it is either a problem with the wires from the console to the controller or the controller itself. In most cases this means you need a new controller. To verify, take off the motor hood and find the green circuit board called the motor controller. With the power on go into manual mode and push the speed up button to a slow speed. If you see an LED light with "spd ctrl" next to it flickering but the belt still does not move then we know the problem is with the controller sending the signal to the walking belt, in which you should check the wires that go to the motor. If they are connected correctly then we know a new controller is in order. If you do not see a flickering light then it means the speed signal never got there and the problem will be with the wires going from the console to the controller. This is called an upright wire harness.

Is there a sheet of paper under the motor hood? It has the procedures for this calibration of the motor speed. Caution ! You should use a plastic screwdriver to make adjustment to the speed control on the motor controller. It is high voltage
