Question about Nordic Track NordicTrack Treadmill, A2550

1 Answer

Our EXP1000 treadmill is about 10 years old and we have not had any problems with it. The belt recently has been going slower than before. for Example, we used to walk at a speed rate of 4.5, now it needs to be at 7.5 speed on the console to have the belt move at the same rate as before.

If belt hasn't been replaced that's your poblem. If that's more than you want to put in a 10 year old treadmill, try lubricating it. That may bandaid the problem for a while. This will progressively get worse over time.

I had a similar problem. Mine was shutting off and also some of the buttons worked intermittently. I thought it was overheating so I bought a small fan and I even went so far as to drill holes in the cover near the motor so the fan would cool the motor better. Turns out it was the console overlay. I purchased a new one from the Treadmill Doctor since NordicTrack will only sell you the entire console, not just the overlay and they want somewhere north of $400 for it. All I had to do was remove the console cover, unplug the old console overlay, peel it off and then stick the new one on and plug it in and I've had no problem since then. It's been over 5 years now since I did this and if I recall correctly the overlay was around $100. Good luck

Only certain buttons on the NordicTrack exp1000 treadmill work.

1) You must check the flexible cord between display board vs controller motor board, and tight very well

2) Try to access to the keypanel and clean with special spray (clean contact you can find in radio schack or computer store).

3) Try to Measure the +5Vdc for I.C. including EPROM, ROM, etc.

4) And try again.

5) Measure if the power supply to display is coming out from the Lower board or Motor controller board. If not the Motor controller is faulty. You must replace it.

Use Dvoltmeter.

Remember 90% aprx the Motor controller board access to the function in the display board, elevation motor, power input, etc.

I have a Nordic Track EXP1000 that wad purchased

Go to click on manual input manufacturer and model name 1000.
Try this calibration procedure:
1) Press the Stop and the Speed Up keys down while inserting the safety key. If this doesn’t work, click on the help topic entitled “Alternate Calibration Codes” for key sequence instructions to enter calibration.
2) Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test.
3) Press either incline key and the incline will calibrate automatically.
4) BE CAREFUL, THE TREADMILL WILL RUN AT FULL SPEED IN THIS NEXT MODE! DO NOT STAND ON THE WALKING BELT. Press the Speed Up key and hold it down until 85 is shown in the Distance window (some models may show the 85 number in another window).
5) If the top speed of the treadmill does not match the displayed speed on the computer console, adjust the max speed potentiometer (pot) on the motor control board. This is the board that the red and black motor wires connect directly into in the motor area. The Max Speed pot is clearly labeled.
6) The max speed potentiometer is a small square with a mobile center and is located in one corner of the board and is labeled MAX SPD. It is near the harness that carries the speed signal labeled H,W,L. Using a small insulated screwdriver adjust this potentiometer clockwise to speed up and counter-clockwise to slow down the max speed of the treadmill. A tiny turn of this potentiometer will make a big difference in speed so be careful when making adjustments.
7) It is not important to get the speed set exactly at the max speed of the treadmill but do make sure to get the speed within .2 MPH of the max speed of the treadmill. For instance if the max speed of the treadmill is 10 MPH, make sure to have the speed set between 9.8 MPH and 10.2 MPH. Some models have a 12 MPH top speed, so please check your manual if you aren’t sure.
8) THIS IS A VERY IMPORTANT STEP BECAUSE YOU WILL GET AN ERROR MESSAGE IF THIS STEP IS SKIPPED.After completing calibration of the speed, press the Speed Down key. The treadmill will automatically return to 0 MPH. Please allow the unit to stop completely before continuing.

If you still do not have belt movement then call iconfitness @ 1-800 999-3756

I have a NordicTrack EXP1000. The walking belt was so far to the left that the edge began to fray. So, I adjusted the belt towards the right and now it slips forward now and then when it gets up to 3mph or...

If the walking belt slips when walked on, first remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both idler roller bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each edge of the walking belt 2 to 3 in. (5 to 7 cm) off the walking platform. Be careful to keep the walking belt centered. Then, plug in the power cord, insert the key, and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened.
If their is still slippage then the drive belt will need to be adjusted.
Find the motor mounts. Many motors in Icon treadmills have a main pivot joint in which a bolt runs the full length of the motor mount. This bolt will require loosening to provide maximum adjustability. Find the set bolt(s) on the motor.
This is typically run through only one side of the motor mount or may be on both sides but it does not run the full length of the mounting. Loosen this bolt but do not remove.

The drive belt must be tensioned by hand. While one person applied increased tension to the drive belt, the other person should tighten the motor set bolt(s) that are described above. Tighten the bolt and test. If the problem is not corrected, if problem persist replace drive belt
