Question about Nordic Track NordicTrack A2550 PRO Treadmill
Manual with troubleshooting guide

Try this calibration procedure.
Turn the power switch on. Remove the safety key. Hold the Stop and Speed Up or Speed Plus buttons down then insert the safety key.
The display should show some numbers.
Press the stop key one time and the display should show some other numbers and some 00's. Press the Incline Up button and see if the Incline begins to move, if it does let it go all the way up and then all the way down, wait a few seconds after it stops, then hit the stop key 4 times. It should be calibrated. If it didn't move then the board or the incline motor is bad.

Likely the cover of one of the motor brushes popped off. Unplug the machine before you pop it back in place, then try it again.
If that doesn't work, most likely it's the motor control board, or possibly the console, or finally just a loose connection behind the console.
But most likely, it's the motor brush cover. I've been seeing that alot with this model.

Sounds like the actual function pad is causing the problem in some cases you'll be able to purchase that part and sometime with iconfitness you have to buy the entire console for a hefty amount you may call them @ 1-800-999-3756 or go to their website iconfitness.com. Good Luck

1. You may have a worn belt and deck problem ( #1 problem on treadmills ). Test by the following procedure:
a) without the power on stand on the walking belt
b) push the belt in the direction it normally turns
c) if the belt is very difficult to turn (on most treadmill) this means that you have high belt/deck friction.
You must physically inspect the belt and deck. The deck should be smooth. The belt should have a consistent feel from side to side (a belt can be worn out without any sensory signs of a problem). If you feel deep grooves in the deck or uneven wear on the underside of the belt, part replacement is necessary. Continued use of your treadmill may damage expensive electrical components. If their is no signs of excessive wear then the next step is to lubricate the deck follow this procedure:
Before applying lubricant, the belt must have the tension reduced and cleaned deck. Loosen the tension roller by following the instructions in your owner’s manual. Do not loosen the bolts in the tension roller too far or the bolts will come out of the roller shaft. This step may not be necessary for your treadmill model or belt and deck condition.
Contaminants are the worst enemy of your belt and deck. Some treadmills may have an excessive accumulation of dirt and contaminants. If these are trapped during the belt lube process, significant damage will occur. Lift the belt and slide a moist towel between belt and deck, slide the towel the length of the unit to catch the contaminants do this a number of times inspect towel and need be use a fresh towel and repeat cleaning let dry then apply the lube in the center upper third of deck then start unit and walk on it @ 1-2mph for about 5 min. You may purchase the lube from National Gym Supply @ gympart.com Part# TM001 or call them @ 1-800-496-7278 their on the west coast. At this point I believe your problem should be resolved if the above procedures have taken care of problem take a look at the next step, as mentioned the #1 cause of treadmill failure is lack of maintenance of the belt and deck.
On occasion, you may have already damaged the DC board if you have high belt/deck friction. If the belt walks freely, you have a different problem.
2. If it passes the belt/deck checks, you may have a DC board output problem. If the belt tests ok and you have a speed variation, try this test:

HI, its seems like the belt on the motor has either slipped off, or you just need to tighten it. best way to find out is to take off the front pannel showing the motor. then stand on the treadmill. start it and you will see the problem.

Tips for a great answer:
The way to tell if your NordicTrack digital console is bad is to troubleshoot it first. If nothing works, you've got a bad console. The digital console is an important part of exercising. A manual machine will still work even if the console doesn't, but an automated machine needs the console to work so you can adjust things like speed, resistance and incline. You also can't use programs or see your time, distance or estimated calories burned without a working console. The two most common reasons that a console will be dim, display bad results, or won't turn on are bad batteries and a problem with the reed switch.
