Your problem is your motor controller is blown out. This happens when you don't replace your walking belt routinely. You'll need a new belt and a new controller. Depending on the model of treadmill you have the parts could range between $250-$400.

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

If the walking belt has shifted to the left, first remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn the left rear roller adjustment bolt clockwise, and the right bolt counterclockwise, 1/4 of a turn each. Be careful not to overtighten the walking belt. Plug in the power cord, insert the key and run the treadmill for a few minutes. Repeat until the walking belt is centered. If the walking belt has shifted to the right, first remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn the left rear roller adjustment bolt counterclockwise, and the right bolt clockwise, 1/4 of a turn each. Be careful not to overtighten the walking belt. Plug in the power cord, insert the key and run the treadmill for a few minutes. Repeat until the walking belt is centered.

Unplug unit then remove motor shroud the 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.
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..
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 a bolt as described above, 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 If your treadmill is equipped with this bolt (very few are) the repair will only require one person.
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 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.

If the walking belt is off-center, first remove the key and UNPLUG THE POWER CORD. If the walking belt has shifted to the left, use the hex key to turn the left idler roller bolt clockwise 1/2 of a turn; if the walking belt has shifted to the right, turn the left idler roller bolt counterclockwise 1/2 of a turn. Be careful not to overtighten the walking belt. Then, plug in the power cord, insert the key, and run the treadmill for a few minutes.

Unplug unit then remove motor shroud then do the following: 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.

1) Adjusting the running belt if the problem: If the walking belt slips when walked on, 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. 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.
2) Adjusting Drive belt: 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.

UNPLUG THE POWER CORD. Using the hex key, 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 edge of the walking belt 2 to 3 inches above 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

there is a plastic spacer at the rack area on the incline mtr- this white plastic spacer has broken, only recourse u have is to unplug the white wire on incline mtr, and never have a incline, or replace incline mtr when you find out how much the mtr is you might want to walk with out incline- if you was in my area, I have them cheaper
