Life fitness treadmill repair

I have an ST35 sport treadmill. Lately we are getting shocks from the handles. A repair service found arcing from the control board the frame. They didn't know how to solve this. Do I need a new board or is there something else I can do?

Go to and get the board.
However the shock imply the you have a ground faulty. you must test the outlet ground with electrician and fix it, before.

SOURCE: life fitness treadmill display: transistor error-won't run

This error shows up if motor controller detects a failed part. This isn’t a reset-able error. Treadmill will not allow workouts until serviced.
Main motor wires/leads could be disconnected at the start of a workout. If the motor is properly connected and in working condition then the drive transistor could have failed. Check Motor Controller.

My Vision Fitness T9250 treadmill. Can hear a low noise when no one is on it but gets much louder when anyone is on it and operating...any ideas where to start looking for repairs?

Try to open and separate the motor carefully from treadmill chasis, turn the motor shaft with hand if it not easily turn or you hear a unsual sound try to open the motor and add a lubricant to motor bearing, and turn the motor on if its still noise replace all the bearings with new one

Typically a non start up of any electrical Exercise equipment raises alot of red flags If this treadmill will not start Check the internal fuse MAKE SURE ITS NOT PLUGGED IN!!!! UNPLUG IT FROM THE WALL
2 If there is NO Fuse and you just bought it new Return it for an exchange.
3 Check your wall outlet for less then 5 Bucks you can buy a wall outlet tester that tells you if your Outlet is good Or Bad.4 DO NOT Attempt to service this item on your own the way they make treadmills you have to have a qualified service tech come out and fix it because the risk of serious shock or death is emminent.

Life fitness 9500 is shocking users? help?

Hi, there is a service bulletin for this problem.
1) perform a continuity test on the power cord between the earth pin at the plug and any exposed metalwork of the treadmill (say an exposed bolt). If you get a reading of less than 1ω - that is good. If higher than this, try another part of the treadmill or trace the cause.
2) Ensure the Power outlet has a good ground - Your electrician could verify this for you.
The most common problems are static buildup on the Striding belt caused by users wearing polyester and scuffing their feet as they are running. This causes static buildup which gets discharged through the user when they come into contact with the treadmill frame.
Happy hunting
