I have nordictrack A2105 and although we "oiled" the belt and replaced motor belt, it still slips. What are we doing wrong?

We recently "oiled" the belt and replaced the motor belt that came in our kit but the belt still slips when we walk on it. Help!

Remove the hood. Turn the treadmill on to speed of 4 or 5 and straddle the walk belt. While the treadmill is running (with good shoes on) step hard on the walkbelt while observing the motor belt and front roller belt pulley. Does just the belt or front roller stop? if so the belt is loose. If the belt does not stop check to see if the front roller stops and the front roller pulley keeps going. If so the front roller pulley is slipping on the roller. If the belt, pulley and front roller are all moving and the walkbelt is the only thing that stops when stepped on then the walk belt is loose. To repair a slipping front roller you have 2 options: 1) purchase a new roller assy or 2) loosen the motor belt and push it to off to the side of the front roller pulley (no needto remove). Realign the roller pulley to the motor pulley. You may have to tap it into alignment. On the inside section of the grooved part of the pulley drill an 1/8" hole thru the pulley and thru the roller housing. (If you drill to the outside portion of the pulley on the left hand side you will hit the roller bearing. Now take a larger drill bit like a 3/8" and lightly countersink the plastic pulley - try not to drill thru the pulley with the larger bit. Using a thin head sheetmetal screw, install the screw so the head is just below the ribbed surface of pulley. If you screw up your first attempt just rotate everything 90° and try again.

SOURCE: When we are using are Nordictrack A2105 for about

From what I am reading the console also goes blank. If this is correct it very well might be a loose connection especially with it being incosistant with the duration of time between shut downs. The lubrication could be the issue but normally it will not cause the console to shut off also. It will normally only cause the thermal switch in the drive motor to shut down until it cools down to approx. 115 f then it will start back up. But with the time frame being so short if the user is around 275 to 300 pounds this could be a cause where the lubrication would be a greater issue.

Good luck.

SOURCE: My treadmill walking belt has moved to the right and slips.

PROBLEM: The walking belt is off-center or slips when walked on SOLUTION: a. If the walking belt has shifted to the left, Start unit @ 1.0 mph using the hex key, turn the left idler roller bolt clockwise 1/2 of a turn to move belt to the right. Be careful not to overtighten the walking belt. If the walking belt has shifted to the right, turn the left idler roller bolt counterclockwise or clock wise 1/2 of a turn depends on the tension that will be on the belt take your time and walk on it to feel the belt underneath you2_bing.gif Repeat until the walking belt is centered.

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.

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

this is a problem with Console Control with CPU, you must replace.
However you must sure if the signal coming out from the control motor to the upper board are o.k Otherwise time to replace the control board since, they send the signa from the inverter to CPU.

A2550 motor belt still slipping after replacing it with a new one. and there is no ajustment on the dirve motor, what to do?


Harvey, there are problems with the front plastic pully slipping on the metal drive roller. It appears that the drive belt is slipping. Just make sure that you rule the pully out first. If after that the pully stops with the front roller and the walk belt, there are only Two different drive belts used, double check the part number. Usually I use a ratcheting strap to pull the drive motor up to the bracket, because the belt is so tight there is no other way to get the motor close enough to the bracket to get the 3/8" bolts to even start into the motor. If you did not severly struggle to install the new drive belt, chances are its the wrong one.

While using my Nordictrack a2550 this morning, the walking belt began to slip very badly. I checked the alignment and adjusted the tension of the belt as per the user's manual but the belt stills slip...


if it really is the walking belt that is slipping keep tightening the adjustment screws till the belt will not slip when you try to stop it ( set speed to about 3 and then with your foot try to stop belt from spinning - you should be able to make the motor and whole machine come to a stop ) make sure it is really walk belt spinning and it isnt the motor belt slipping. (if it is motor belt slipping when you try to do the stop the belt trick i just described you will see the walk belt and front roller stop but still hear the motor turning) once you get walk belt tight enough so it doesnt slip then you can worry about keeping the belt centered.

let me know if you need more help on this and let me know how the stop the belt test went

good luck!

I have a Nordicktrack A2105. When I turn it on the belt runs real fast like a second then stops everything on the panel is working as if the belt is still working but its not. Can there be something...


there is an optic sensor on the top roller that drives the belt. if it has fell off the computer can not sense the rotation. you may have to remove the cover where the motor and top roller is and inspect that the sensor is in place and no dirt is obstructin the signal. good luck to you.

Walking belt on NordicTrack C1900 is to loose, how do I tighten it? When walking on it when u get to level 4 it just about throws u


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.

When we are using are Nordictrack A2105 for about 5 minutes, it just stops and shuts off. The motor and the display both stop. Then it comes back on and works for about 2 minutes and the samething...


Its stopping because its drawing too much power.  most likely your belt needs lubricating on the underside.  check out your owners manual for instructions.  buy the lube from Icon fitness.  If that didn't help, then most likely your belt is already fried and will need replacement,

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
