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 for more help if needed.

Treadmill belt doesn't run smoothly

First of all lubricate the treadmill. If it didn't workout then try to tension the walking belt.

When on treadmill there is a "studder"

Check if the running belt is lubricated. You can't run an engine without oil. So, spray a good quality silicone lubricant on the base of the running belt. It is best if you spray on a lint free cloth just enough to make a wet patch. Do it outside so that no spray residue lands on the floor and becomes slippery or lands on the carpet and stains it, then return inside and lift the treadmill running belt and soak or smear the base with the wet patch of the cloth and run for a full minute. Then lift the belt again and give it another swipe on the entire base, then feel the base with your fingers or hand to see if it feels wet and smooth. Run the treadmill for another minute at slow speed, otherwise the liquid can fly and splatter on wall or floor. If it still hasn't solved the problem, then it must be the motor brushes, or it may be set to run slow and fast according to the running settings on the console. Mine does the same thing if it is programmed to do 1 minute slow and one minute a bit faster. Good luck.

It runs just fine, then you get on and it slows down almost to a stop.

This means that the motor is having to work too hard to rotate. It could be one of a couple of problems. If the machine is old then it potentially could be the motor itself. it may be going bad. On most models the motor has a lifetime warranty so you can check your owners manual for that. If you have not lubricated your walking belt in over 3 years or so then it could simply be a lubrication issue. To check this stick your hand on the underside of the walking belt and feel the belt. It should feel like a screen door. If it is smoothed down then there could be too much friction that is not allowing the belt to turn. When you pull your hand it should feel like you have been eating popcorn, kind of oily.

My IFIT treadmill 860 keeps turning off after 2 mins why

This machine has what they call a thermal switch. It is designed to shut the machine off if it gets too hot. This heat is caused by friction. Friction is caused 99% of the time by the walking belt or the drive belt. If it is the drive belt then it can be solved by either applying a treadmill lubricant (must be made for treadmill belts) or by purchasing a new belt. If you feel the underneath side of the belt and you feel a screen door type feeling you just need lubricant. If you feel a smooth surface you will probably need a new belt. If you have lubricated in the past year and your belt has the screen door feel then take off the motor hood cover and check the drive belt. If it is worn then you will need to replace that. You can purchase either of these products from the manufacturer, at a couple of other places that may have them for discounts are,, or
