Belt stops running while standing on the treadmill

If we use the treadmill daily it might need maintenance regularly. Running of 180 hours on the treadmill might lose the belt. Drive belts usually last for longer time of 5 to 7 years.So you have to adjust the tension of the belt.
Keep enough tension in the drive belt
If a user wants to improve the motor efficiency it is necessary to connect the motor to the front wheel which helps the belt to spin.
Too little tension results in slippage, excess heat and high-pitched noise, or too tight belt produces tension causing stress on belts, bearings, and shafts. Prevent premature motor failure by adjusting the belt at a suitable place. The belt should be fixed half an inch of play.
To improve the efficiency of the motor align the belt properly and lubricate it on time. Keep in mind such useful options may help the user. When the belt slips off the track, the friction between the belt and drive pulleys causes the belt to overheat. If you hear a high-pitched noise, it's time to replace the belt with a new one.
How to Ascertain that the drive belt can still be used?
If you test Front-wheel by walking on the treadmill and the belt stops but the motor is still moving, It means that the drive belt is loose and needed to be tightened or replaced.
Keep in mind
There are some exercises that are not suitable for the treadmill like jumping on it. This kind of usage can be rough on your treadmill and lead to your treadmill belt slipping.

see if you can remove the motor hood and look at the drive belt. it is a little belt from the motor to the front pulley to turn the walking belt. its either broke or fell off

Hello, It sounds like you have aslipping front roller pully. Remove the motor hood and watch the front roller while you are on it. Once the belt is moving slowly, try to stop the wlak belt by planting your fett for a second, if the walk belt stops, but the drive belt and motor continue to run, the plastic pully is slipping and the whole front roller will need to be replaced.

Hope this answers your question.

Pull the hood off. Stand on the sides of the walk platform and start the belt at 4mph. Take one foot and step on the walk belt hard. Look at the pulley on the front roller. Does the pulley continue to turn while the roller stops? If so, the pulley is slipping in the roller (which is a press fit). Replace the front roller or remove the motor belt from the pulley.Align the pulley with the pulley on the motor by tapping with a mallet. Drill an 1/8 hole throught the pulley and roller. Countersink the pulley hole so a small head screw will be under the pulley groves. Install screw in this hole. This is called pinning and is a pemanent fix. If both the pulley and the roller stop together when the belt is stepped on the motor belt is loose. If only the walkbelt stops when stepped on, the walkbelt is loose.

It sounds like you either have a loose walk belt or a slipping front drive pully. The walk belt shoould be tightened so that you can pull up on the edge of the belt about 2 inches. If that is OK, pull the motor cover, start the treadmill and walk trying to stop the belt with you feet. Watch the drive belt this time (the small one going from the drive motor to the front drive roller), if this belt stops, you need to tighten motor, or replace if it is older/wornout. If the drive belt keeps turning fine, watch the front roller and see if the pully connected to the drive belt keeps turning while the roller connected to the walk belt stops, if so you need a new front drive roller.


Hope this helps

Before beginning this repair: Check to make certain that the drive belt requires adjustment. Check out belt slipping instructions or with the motor cover removed, walk on the belt normally and try to stall the belt to make it slip. Be careful during this test. If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. If the motor, drive belt, and front roller continue to turn when the walking belt is stalled, the problem is with the walking belt slipping on the front roller. If the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley.
Step 1- 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. Some models have a single jack bolt and others have an auto tensioner. Single jack bolts are the easiest to adjust. Step 2- 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(s) but do not remove. Jack bolt models will have flat mounts and may contain up to four bolts. Step 3- Look for a bolt that will tension the motor. If it has this bolt, it typically runs in the same direction parallel with the drive and walking belts. If your treadmill is not equipped with this bolt, skip to Step 4. If your treadmill is equipped with this bolt (very few are) the repair will only require one person. Using 2 7/16" wrenches, make a few turns to this bolt, tighten the bolts from Steps 1 and 2 and test your treadmill for slipping. If belt continues to slip, repeat Steps 1, 2, & 3. If a second attempt does not repair the problem, skip to Step 5. Step 4- If your treadmill is not equipped with a bolt as described in Step 3, 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 in Step 2. Tighten the bolt from Step 1 and test. If the problem is not corrected, repeat Steps 1, 2, & 4 and retest. If problem persists, skip to Step 5. Step 5- If you have arrived at this step, let's make sure you have a drive belt tension problem. With the motor cover removed, walk on the belt normally and try to stall the belt to make it slip. Be careful during this test. If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. If the motor, drive belt, and front roller continue to turn when the walking belt is stalled, the problem is with the walking belt slipping on the front roller. the problem. Another possibility is that the drive belt has worn down. In some cases, belt dressing may help correct the problem. If not, the drive belt must be replaced. Step 6- The belt should be able to be turned by hand at approximately a 90 degree angle from its normal operating position

If the walking belt slips when walked on. Using the allen wrench, turn both rear roller bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each side of the walking belt 3 to 4 inches off the walking platform. Be careful to keep the walking belt centered. 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.

Hi James
Unplug unit remove motor shroud then plug unit back in , press start and begin walking on the belt normally and try to stall the belt to make it slip ( planting foot to stop the belt).
Be careful during this test. If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. Here is the procedure for adjusting the drive belt.

Using 2 7/16" wrenches, make a few turns to this bolt, tighten the bolts and test your treadmill for slipping. If belt continues to slip, and if their is too much tension ( you should be able comfortably twist the drive belt 90 degrees ) then replace drive belt.
If the motor, drive belt, and front roller continue to turn when the walking belt is stalled, the problem is with the walking belt slipping on the front roller, here the procedure adjusting the walking belt.
If the walking belt slips when walked on, first remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller bolts clockwise, 1/4 of a turn.When the walking belt is correctly tightened, you should be able to lift each side of the walking belt 3 to 4 inches off the walking platform. Be careful to keep the walking belt centered. 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 the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley. If this is the problem, you will notice it because the plastic will usually make a loud squealing sound on the metal front roller. The front roller assembly will need to be replaced and the drive belt must be replaced also. We suggest replacing the drive belt as well because it is a low cost item and will most likely, have suffered unusual wear from the problem. Another possibility is that the drive belt has worn down. In some cases, belt dressing may help correct the problem. If not, the drive belt must be replaced.

If the front roller is stopping with the walking belt, it is the drive belt. You may be able to tighten it, if it's not too old. The easiest way is to remove the belt by turning the motor by hand while pushing the belt away from the motor. Then adjust the motor back a 16th to an 8th of an inch or so, put the roller side of the belt on the roller side of the pulley, so that you have enough slack to put the belt on the motor. Now, while you pull the belt onto the front roller pulley, turn the motor and walk the belt back on. If it won't go on, this way, you probably have the motor too far back, making it too tight. Good Luck!

If you can stop the belt. You need to be aware that the drive belt can also cause this problem so I suggest that you remove the motor shroud and when you are adjusting whether the front roller is moving and the running belt has stopped (adjust back rollers) or the roller has stopped and motor is rotating ( adjust Drive Belt)
