Question about Life Fitness 91Ti Treadmill

1 Answer

Life Fitness Treadmill 91Ti. Came in to work and the machine was running very fast and had an overspeed error. Now on start up the belt runs very fast. Input screen says to pick a workout, but you can't. Also you cannot control the speed or stop the belt without turning the unit off. There are only 313 hours on the unit. I replaced the opto sensor, and I still have the same result.

    There is not a software calibration option when I go through the system menu. I went through all the options: System test, belt/deck test, etc. The belt just runs i cannot stop it our adjust the speed. It is stuck on high speed.

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.
Solution
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.

Belt keeps slipping on treadmill and belt is all the way back


If you have adjusted the tension on your belt to the max, it is more than likely time to replace your running belt. The running belt naturally stretches over time. I would suggest replacing the belt and flipping your deck. If the deck has already been flipped once, then you would need to replace the deck as well.

Lifefitness treadmill belt sticks even though wax bag is full


It may not be sticking, but instead slipping on the front roller. You can resolve this by simply tightening the running belt. This adjustment will be done by using the rear roller.

Error 1 - Start up error. This is caused because the belt was commanded to move and the opto (speed sensor on the motor) has not seen any movement or the belts movement was interrupted prior to it reaching its commanded speed. To fix Verify opto operation in Diagnostics, Motor Test
Mode, Section 2. Verify DC voltage at connector P6 pins 1 and 2. Verify that LED 4 on the Motor Controller flashes as the motor moves. Let me know if you need any more help. Fitness Fix-It
