This probably did not happened suddenly right? the problem is not the motor however you can easily check the blue capacitor for peace of mind. with the power disconnected, disconnect one side off the capacitor from the top. with a ohm meter put the 2 probes on the cap,you will ear a temporary beep sound from your meter, then reverse your probes on the capacitor and again a temporary sound that mean your capacitor is good and your motor will run OK.
Your problem is more then likely your run belt and bed assembly. When new, these are coated with a wax of some kind for slipping, has you use the machine wax wears off, and so is the belt. You can see a black rubber dust at the rear of the machine. And so resistance increase when pressure is applied on the running belt.
Just behind the on/off switch where the power cord goes in, there is a auto reset 15 amp breaker that trips when too must resistance against the motor increase the amperage over 15amps. At 7 min/m on your speed setting and if the belt is adjusted correctly with nobody on, the motor pull about 6amps, with someone like me 180lbs, the motor pulls an avg of 10amps with a new belt.
If you have a clamp amp meter you can test it yourself.
2 parts you will need to fix this; 50985-101 (bed assembly) and 36355-101 (run belt 17 X 110) This is real easy to install.
make sure these parts are for your machine model # as they did increased the width of their belt over the years
Since 1998 I had to replace these parts 2 times with an average of 3 people using the treadmill every day. This is a good machine and if everything else is good it's worth it. I paid $300 for these parts, i'm sure if you shoppe a little you can do better.
Have a good one

Hi Rendra,
Try this:
Switch the treadmill off and then on again.
Push the "minus" speed button and the "stop" button simultanuously.
If all is well you will now have entered the maintenance mode.
Next push the "plus" speed button and the "stop"button smultanuously.
Now you you've reached the error mode.
Push the "plus" or "minus" speed button to browse the error codes untill you've reached "L er".
The push start to erase the message.
Turn the power off and then on again to restart the treadmill.
With any luck the error has disappeared and the treadmill will function again. If not.....you'll have to contact Kettler.
Btw...This error occurs when the belt is "pushed" by the runner. For example when you put weight on the handlebar and the push your feet backwards.

your running belt might b on 2 tight or u dont have enough power going 2 the motor make shure u have a designated power line 2 your machine

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.
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.
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.
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 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.

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.
