No torque on Nordictrack T9si

Hi. I have a Nordicktrack T9si. Teg problems started with the walking belt hesitating whilst I was running. Recently the unit went dead and was tripping my fuse board. I have replaced the main controller board and the unit now runs but has no torque at all. I have cleaned and lubricated the surface. Any ideas what next?

1) you must LUBE the deck belt and rollers bearing with wax or silicone.
2) if the problem persist, TIME to replace the old board deck belt. Since you must lube the deck about 150 miles aprox.

SOURCE: Nordictrack motor will not run when start button is pushed.

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.

SOURCE: My nordic track treadmill's walking belt stops

Unplug the unit remove the motor shroud inspect the drive belt if the rubber feel slick then my recommendation is to replace the drive belt. Adjusting the drive belt may take care of the problem if you do not need to adjust it too tight. If you choose to do the adjusting and feel you have adjusted the running belt thinking it would resolve the slipping, then back the tension down until it the running belt is slipping then adjust until the slippage is resolved.

SOURCE: I have the Nordictrack C2500, and for the second

You have a wire harness that attaches the upper board to the lower board. You may have to pull that harness thru the uprights ( Attach a fishing line so you can either pull a new harness thru or the original one ) and inspect it for snags crimps or broken wires also use a meter to a continuity check on the harness ends. Since the the command signals travel thru this harness also check all connections on the lower board. Its starting point

SOURCE: walking belt on NordicTrack C1900 is to loose, how

Tighten the rear roller bolts evenly with the unit off. The correct tension is when you firmly lift up on the right and left edges in the middle of the walking belt and get 2-3 inches gap above the walking board. If one side is looser than the other, the walking belt may wander sideways. Turn the rear roller screw on the side that it shifted to in a clockwise manner(1/2 turn at a time). Test on a low speed and adjust as needed. (you may manually recenter the walking belt with your foot if it shifted too far to one side and is rubbing on the plastic edges.) You likely have a worn motor belt that needs changing or even a pulley on the front roller that is slipping and needs replacing. They all cause slippage.

Belt stops when you stand on it

Hi, yopu have a loose belt or a bad front roller, remove the hood(front cover), and start and run the treadmill. Get on it and watch to the left where the belt is, you are watching to se if the front roller is stoping when you walk on it. Most likley. you have a stripped plastic pully on the front roller. The belt and the pully turn fine, but where it is pressed on the steel drum (roller), it just spins. You need to replace the front roller.

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

Nordictrack EXP 1000 Treadmill Quits after 10 Minutes

Hello There, Thank you for all the information. It appears as if your walk belt is worn. What is happening is the friction from the bottom of the belt is actually causing the motor to overheat (there is a thermal cutout inside where the 2 blue wires go) When the belt wears the cloth on the underside becomes flattened out causing too much surface area to contact the walk board, thus the extra friction.
To check your walk board you can loosen the adjusting bolts on the rear and while lifting the walk board look underneath. If there is any wear/white areas then you will need to replace the board as well. You will be able to tell by just rubbing your hand across it and check for any places where the black film may be coming off.
Also the only time you really need to replace any of the rollers is when the bearings go bad or the pulley on the front roller separates. The rollers are about a 1% chance of causing this problem.
Good Luck! and great question, Tim

Nordictrack EXP1000i stopped in the middle of program

Your drive motor is over heating. Usually caused by friction from the walk belt. The belt needs to be lubricated. (silicone only) Loosen the adjusting screws on the rear of the macine ten revolutions lift up the belt and using a spray silicone lubricant (from any big retailer) spray a light film on the deck (walk board). Retighten the adjusting bolts ten revolutions. If this does not help I would suggest replacing the walk belt. Good Luck, Tim
