Try to use soda on a piece of smal rug and swipe it on the area

most commonly at the end of the walking flat form. on both side end there are hex heads bolts that is what we use to adjust the belt on proper tension or tightness . and it could be use for keeping the walking belt in the middle of the flat form.

the motor drive assembly is seperate from all the electronics that you program and the incline motor ,although it may not work if there is a "Saftey 'Clip that attaches to the machine and clips on yourself it wont work without this "or if this Magnetic Clip is 'Faulty, If you can lay Machine down on its side or look for a plastic cover at the front or underneith and see if you can Unscrew and access the motor ..there may be a Overload Reset Button or Fuse just after where the Main Power Cord goes into the Tredmill. tred mills also are common for getting pet fur and hair in the motor which can get caught up in the Brushes, (I Think it is Most likely a Fuse or overload switch that is inline with the main Drive Motor.(if you can post exact Model# of TREDMILL I can have a look at the Electrical Diagram and make a more accurate conclusion ,Cheers!

check and test safety switch then motor possible overheat or failing

Your manual may have the instructions http://www.manualsonline.com/

Check if the machine is going through some kind of calibration, evidenced by humming of a motor. This check may take a couple minutes. If there is still not activity after your patient waiting, something may have to be repaired by an authorized technician or mechanic.

This is conjecture but the incline motor is likely attached to a worm gear that lifts and then lowers the incline. There is also likely some kind of automatic "clutch" that disengages the motor from the worm drive after the raise or lower sequence is complete. If this clutch is broken or malfunctioning, then it may be trying to "grab" the worm gear when it is not supposed to (when not raising or lowering) or conversely, it may be losing its grip on the worm gear when the incline is happening. The clutch is likely controlled by an electric solenoid which may be malfunctioning. All this to say that it may be time to call a repair person.

I'm guessing that a schematic would be difficult to obtain because the Nordic Track design is proprietary. The incline up/down calibration might be running at start-up which can take a couple minutes, after which, the machine returns to "normal" and buttons now respond. If this is not you case then a repair person may have to intervene.

The backlash or free play in the incline motor or gearing is likely making the calibration fail. I view the calibration as a "courtesy check" that the Nordic Track performs to let you know when some component is failing or has failed. It is annoying and inconvenient when it fails, but it is something like a "fix engine" light on a car. It is telling you that something needs immediate attention, likely needed to be done by a technician or repair person.

You may have to call a technician. The motor that drives the belt could be shot. Also, a simple test can be done to see if it is a capacitor: Try making the belt turn by moving your feet and see if the motor "kicks in" and moves the belt by itself. If so, it is the starting capacitor, something to save a repair person some time, but probably will not reduce the cost of the service call...

There are a number of possibilities which a technician may have to help with and fix your machine. Here is a possible explanation: Most electric motors include a capacitor in their circuit (likely these days to be a component on a circuit board, a place where I give up quickly due to the complexity). The capacitor acts like a "primer" that gives the motor a little "kick" to get it moving. This capacitor is automatically switched out of the circuit when the motor comes up to speed. When a capacitor is non-existent or fails in the circuit, the motor will still function normally after you give it some "manual encouragement" as you described by making the belt move with your feet. On older motors, I have seen capacitors sitting in a clamp directly on the motor body. This would be an easier fix than messing with a circuit board to find the bad component.
