If you can walk on your treadmill but you get a burning smell from it, you have a bad problem and discontinue use immediately and unplug the treadmill.
Burning smells are most commonly associated with the following problems:
1) Very high belt/deck friction.
2) Short in the motor.
3) Short in the wiring or electronics.
4) Literally cooking the lacquer or cardboard core (on cheap machines) in the motor from belt friction or a drive system
obstruction.
Friction is the #1 cause of this problem. Many cheaper treadmills have a motor with a cardboard core (people wonder why we are so
down on cheap treadmills) and if the voltage and amperage through the motor heats it up sufficiently, it begins to smolder. If this is the
case, you normally have to replace the belt and the motor and inspect the deck. If the armature has cooked enough in the motor, you
also have to replace the motor.
If the belt and deck check out OK, check for a short in the motor. You can run the motor with an independent power source like a fullycharged
cordless drill battery to see if the symptoms are the same. Click on the following link for our motor test.
If the belt and deck check out and the motor is OK, then check your wiring and electronics for signs of scorching and replace the
appropriate part(s).

1) 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. 2) 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, . 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 If a second attempt does not repair the problem 3) 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. 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 entire front roller assembly repaired or replaced (see the help topic on replacing a pulley) and the drive belt must be replaced. 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.
