LS1 appeared on the console,motor is not responding
Thank you by you request, I will try to help you inmediately.
The code LS, means Loss os Signal.
TreadBelt is not Moving. Plug the machine in receptacle of the wall, is some Red lamp on?
if Yes.check Motor and Connection + Circuit Breaker or Fuse , You must need a DVOM(digital Voltimeter for check that. Do not worry, I will give some indication for to use.
With this you must find, if there is the motor, some connection loose, of breaker tripped or fuse bad replace.
There are four typicalcauses for this problem (listed in order of our experience:
1) The walking beltand/or deck are worn. (85% of the time)
2) The walking beltand/or motor belt are too tight- if you have adjusted either recently. (8% ofthe time)
3) The motor has losttorque and needs brushes or has demagnetized. (5% of the time)
4) The controller isdropping output. (2% of the time)
a) Walking Belt is Worn:
The only certain way totest for a worn walking belt is to take a DC amp draw (if you have a DCtreadmill) or an AC draw (for AC). Trying
to look at the belt or afeel test is highly unreliable. Better tests, if you lack a DC ammeter (theyare expensive for a good one), are a
coast test or an inclinetest. To test the deck, go back to the Troubleshooting section and download thebelt and deck inspections
The coast test is to geton the treadmill as the lowest incline setting and walk on the treadmill at 3 MPH. Pull the safety keyand it should
take you 2-3 full stepsto stop (this is a general rule...some like a few Tunturi models stop on a dimeeven with a healthy belt but most
this tests works wellupon). Fewer steps indicate high friction.
The incline test is toput the treadmill at max incline and walk on it at 3 MPH. If the treadmilloperates normally at max incline but bogs
down at minimum incline,replace the walking belt. Gravity takes over for the drive system eliminatingthe friction problem. On some
heavily worn walkingbelts, this test will not eliminate the problem.
B) Walking Belt/Motor Belt too Tight:
If you have adjusted thewalking belt or motor belt recently, check for this problem. When the beltsstart slipping, some people just crank
down the belts and ontreadmills, tighter is not necessarily better. The tighter the belts, the morethe drive system has to work to keep
everything moving. Youshould be able to lift the walking belt (with the treadmill unplugged) in thecenter of the treadmill about 3"without
straining. Tighter beltsshould be loosen but make sure you don't create a dangerous slipping situationby loosening.
The motor belt (with thetreadmill unplugged) should be able to be turned by hand to almost a 90 degreeangle from its normal operating
position. Loosen the beltif too tight. Make sure to test for slipping
and if it does with theproper tension, replace the motor belt.
C) Needs Brushes / Demagnetized Motor:
Typically when we find amotor that has lost torque; it needs a new set of motor brushes. Typically wecan make brushes for almost any
motor if we don't alreadystock them. Motor demagnetization is not that common but it does happen and itis normally easy to diagnose.
If you have confirmed thebelt and/or deck is not worn and the belts aren't too tight, you can test for amotor torque problem..
DO NOT USE YOUR HAND OR ANYOTHER BODY PART TO IMPEDE THE MOTOR...YOU WILL LIKELY LOSE YOUR BODY PART
IN THE PROCESS IF THEMOTOR IS GOOD.
The step to test for themotor is to use a foreign object preferably on a long shaft. First determinethe direction of the motor spin (most
have directional movementprinted on the motor tag), then apply pressure with an object with downwardpressure on the flywheel in the
direction the flywheel isturning (do not attempt to put force against the rotating direction of theflywheel as you can easily injure
yourself). If you canslow the motor, typically you need brush replacement.
To test fordemagnetization, the motor must be disassembled. Once you have the motorretaining bolts removed, remove the motor core
by sliding it out of theend of the housing. If the magnets pull the core
against the housing andit is difficult to remove, the magnets are good. If the magnets do not attractthe core, the motor has to be
This is the most uncommonof the causes. Typically replacing a controller in this situation will notsolve the underlying problem and then
you will end up replacinga belt as well as a control. Normally if a
control is droppingoutput, it will do it with a person on the belt or not. Tests of DC outputdropping is normal in many controls since they
have a current limiterwhich will automatically drop output to prevent burning up the board. This isbest diagnosed by eliminating the
other possible problemsfirst. If you are left with the control as the cause,
