There is a belt hidden under the hood that connects the front roller to the motor (motor/drive belt). Start the treadmill at 3 or so and carefully apply pressure to the walking belt until it slips/stops. Watch the front roller. If it continues to spin when the walking belt stops, it’s the walking belt. It the front roller stops with the walking belt, the motor belt is loose and needs adjusted or replaced.

To adjust the walking belt, locate 2 hex head bolts, one on either side of the deck on the very back of the machine. These bolts will be recessed inside the plastic covers. Your treadmill came with a tool for this, but if you can’t find it, a standard (not metric) allen wrench kit will work. It’s helpful to have a wrench in each bolt so that you can adjust them at the same time, but one will work.

The allen bolts thread directly through each side of the rear roller. As you tighten the bolts, it pulls the rear roller away from the front roller, tightening the walking belt. This also centers it; if you tighten one bolt, it pushes the belt towards the center of the walking deck away from the bolt you’re tightening. So if the belt is too far to the right, tighten the right bolt and it will move towards the center.

Place your wrenches in the roller bolts and turn the machine on to 3-4 miles an hour. Keep your fingers clear of the belt, it will eat them. This method is quick, because you can see the belt move as you tighten one side or the other. It takes a few seconds, but if you tighten the right bolt for instance, you will see the belt move to the left. If the belt is loose but centered, tighten each bolt ½ turn and then get on the machine and see if it slips. The user manual will tell you to pull it up a couple of inches to test the tightness, which is a relative method and doesn’t necessarily work. My wife can pull on the belt and get 2 inches, and I can probably get 3 or even 4 if I’m showing off. The best way to test it is to gradually tighten it until you can run on it without it slipping.

You should lube the belt a couple of times a year. You can get them from iconfitness.com

Good Luck!

I have a Horizon LS925T treadmill. It seems to jerk. I don't think the belt is slipping, more like the power roller is erratic. It rolls smooth then slows for a second which jerks the belt. Help.

Hi There, This sounds like the control board may be failing. Can you see the control board? Check the 3 larger capacitors for doming or bulging on the tops, which is a sign of high internal heating of the capacitors. This board, 032671 can have issues with these caps. Lubricate deck well, free spin the walking belt by hand to feel for jerky rollers and flat-spots in bearings, if all feels smooth, that controller is most likely at fault or a failing motor with partially shorted windings. Contact [email protected] for more help if needed.

The steering just became much harder to turn while

1. Check if the belt on the power-steering pump is not slipping. Replace belt if so.

2. Check for oil leaks (if yes, there is air in system).

The disc tray will not open. The display shows "open" and it makes noise as if it is trying to open, but it doesn't.

There is a small loading belt that is slipping. The noise you hear is the loading motor. When in the loaded position, there is a "clamper" that magnetically attached to the hub assembly to clamp the disk in place. It takes quite a bit of force to open this up. If you feel comfortable working inside the unit, you can try to gently lift up on the clamper assembly while you are trying to open the tray. That may provide enough to release the tray to open. Replace the loading belt with a new one and your problem should be resolved.

Head jammed in record

Most likely one of the belts has slipped a bit and the unit is stuck in the middle of a transition. Normally, a power up will "reset" the mechanism. Try that first. The owner should hear the motor run once the power has been turned on. If that is the case and the mechanism does not clear, then the belt is slipping and can't return the mechanism to a known start state. The unit will need to see a servicer to reset it and to replace the main drive belt.

When running, belt feels like it gets caught or slides off track.

Sounds like the belt is loose. To tighten the belt, start by locating the two bolts that adjust the rear roller (one on each side of the unit in the back). Run the unit at about 3 mph. Tighten the bolts a 1/4 turn at a time. Make sure that what you do to one side, you MUST do to the other side or the belt will get off center. After you tighten it 1/4 turn, check the belt to see if it is still slipping. If it is then tighten the belt 1/4 turn again. Continue until the belt does not slip, but do not tighten the bolts more than 2 full turns.

Treadmill may be slipping

Depending if this is a new issue or old, It could be a couple of issues. Check the belts for slipping. Proper tension on walking belt (check your manual) or drive belt -remove the cover and you might be able to see if the belt is slipping or it could be a load issue (electronics not sensing added load fast enough). My bet is belt tension. Also Lubricate,lubricate,lubricate

Heads are not turning, therefore tape is not moving.

This unit is driven by belts. I would suspect that the belts have dried up a bit and are slipping. Replacing the belts should resolve the problem.
