Just purchase today this treadmill. After 10 minutes it shut down with a LS1 low speed code....unplugged the unit and took out the key, still codes the same. Belt and Motor do not respond
I had all the low speed codes. Company sent new sensor and boards. I still had the same problem. My solution was found when I hopped on treadmill with motor cover off. I discovered the motor was turning properly but the belt drive was slipping. The belt was all oily so I cleaned the belt then tightened the motor tension with the adjustment screw. :)
Hello,
I just repaired this on my F80 after the factory sent out almost all new replacement parts. In the end, this is what fixed the problem: (This will be easier if you use a friend).
1. Remove the shroud on the motor (at the front of the treadmill) by loosening two screws at the front and one on each side (Phillips).
2. Find the greenish control board (looks like a motherboard kinda). Locate a small green light at the top left of the board. With the machine on, slowly push the belt in the normal direction. The green light should flash.
3. If it flashes single flashes as you slowly push the belt, go on to #6.
4. If it double flashes as you push the belt, find the speed control. It is mounted on the opposite side of the machine from the board, near the edge of the front belt roller (on the left side of the treadmill if you're using it). It's a little black piece of plastic mounted with one phillips screw on the side of the motor box. Loosen the screw and adjust the speed controller as far as it will go toward the belt. It should be lined up parallel to the front roller edge. Now check the green light again by pushing the belt slowly. If it still double flashes, adjust the speed controller location a fraction of an inch back. Keep doing this until the green light only gives a single flash as you slowly push the belt. (I know it's tedious, but it's the only way).
5. Now try the treadmill. If it works, you're set. If it still throws a LS1 error, go to #6.
6. On the greenish control board, locate a round "diode" thingy with a blue top and a tiny round white phillips screw adjustment on the very top. This will probably be on the left side, center of the control board.
7. Turn on the machine and run the manual program at the lowest speed (.5 mph). Using a very small screwdriver, while the belt is running (CAREFUL!), adjust the tiny screw adjustment in very small increments clockwise. (If the screw were a clock, adjust only one clock number at a time). As you adjust, watch and listen to the belt and rollers. When the belt and rollers begin "surging" (you'll know it when it happens), back off the screw adjustment until the surging stops.
8. Stop the treadmill and have a friend get on. Using the manual setting at the slowest speed, have the friend walk on the treadmill. If it's surging or jerky, stop the walking and adjust the screw. Continue to do this until the belt is running smooth and there is not jerking.
9. Turn off the machine and restart. Try it out CAREFULLY! If needed, redo the calibration program. You should be all set.
I've the same problem. I tried #3 but the green light does not flash at all. Does this indicate the sensor is faulty
I went through the calibration procedure a couple times, adjusted the speed sensor from 1/8''to 1/2''from the magnet and a
Sorry about that but I was about to mention I also checked the sensor cable connection to the circuit board

Hai ,
pls check 12pin communication cable and speed sensor wire also
SOURCE: Treadmill displays incorrect speed. I always run
Treadmill is more than likely in metric. Most mill (if in english measurement) will start out at .5 metric usually star at .8 Not sure how to change for treadmill but it should be in the manual.
SOURCE: F63 sole treadmill, low speed error when inclined
If the calibration does not pass you may need to check the speed sensoralignment. You must understand the instruction for calibration is under the hood for motor.
1) Remove the motor cover hood by loosening the 4 screws that hold it inplace (you do not need toremove them completely).2) The speed sensor is located on the left side of the frame, right nextto the front roller pulley (thepulley will have a belt around it that also goes to the motor). Thespeed sensor is small and blackwith a wire connected to it.3) Make sure the sensor is as close as possible to the pulley withouttouching it. You will see a magneton the face of the pulley; make sure the sensor is aligned with themagnet. There is a screw thatholds the sensor in place that needs to be loosened to adjust thesensor. Re-tighten the screw whenfinished.
2) if the problem persist you must Test the main motor for open, ground 3) the main control board faulty. See the block diagram that I did as person like you that understand that 90% of functions the main motor controller board has effect.
good luck. sincerely. God bless you.
