True Treadmill Errors and Service Messages

• The True 600, 700, 725 and 750 series treadmills are equipped with built-in diagnostics and maintenance reminders that display either an error message or service message as they occur.
• The error messages that may be displayed by the built-in diagnostics are as follows:
  • E1:INCLINE
  • This means that the incline is moving when it has not been commanded to.
  • E1:MINIMUM
    • This is a minimum incline calibrating error that can be cleared by calibrating the incline.
  • E1:RANGE
    • This means the difference between the treadmills zero position and maximum incline is not sufficient.
  • E1:STALL
    • This means that the incline is not moving when it has been commanded to.
  • E2:OVERSPEED
    • This occurs when acceleration greater than 2.1 mph occurs as this is greater acceleration than anticipated.
  • E2:CAL
    • This means feedback cannot reduce or increase speed to target and error can be cleared by calibrating treadmill.
  • E3:EEPROM
    • This error happens when a data error is detected on the EEprom. The control panel needs replaced if this error occurs.
  • E5:SENSOR
    • This error occurs when there is no speed or RPM feedback detected from speed sensor.
• The service messages that may be displayed by the built-in maintenance reminders are as follows:
  • S1:LUBE

  • S2:CLEAN
    • This service message displays every 500 miles and is your prompt to clean the treadmill.

nope its a sensor

This may be a faulty speed sensor.
Or a faulty LCB

Technically are 2) a) Reed switch b) Speed sensor.

1) adjust the speed sensor, see the diagram attached, test for open or faulty. clean it very well. tight the connector very well

2) LUBE the treadmills very important . do it with silicone or wax. Read your onwer manual for verification.

God bless you

RESET the machine. Use your owner manual read section troubleshooting and proceed according.
God bless you

1)You must shure the motor has level, use some one.use the washer according with the new motor.
2) Tight very well with wrench.
3) Alignment very well the drive belt, not much tension
4) Lube the deck belt with the instruction manual.
5) Lube the rollers bearing very well.
6) Try to run the software calibration for diagnose, and troubleshooting
God bless you

Dear Sir:
1) Lube the deck belt very well, as your instruction manual indicate for maintenance.
2) Try to Run software calibration after you fix it. For easy diagnose and troubleshooting.
3) The elevation motor can be faulty for lack of maintenance too, again Run the software calibration.

sincerely. God bless you

SimplerFASTERSolution So, I had the same problem. After removing the motor cover I checked everything out per earlier instructions. Everything looked great. Having been a software geek for as long as I've been running (35 years), I as inclined to believe this wasn't a hardware problem at all. It appeared to me that the system just needed to be recalibrated. So...here's what I did. I turned the treadmill on and selected the "Manual" program and hit "Start". The monitor, as usual, counted down 3-2-1. As soon as the rollers started to move I hit the "Slow" button on the right upright several times so I knew that the treadmill was running at it's slowest speed. I then started walking on the belt. I started tapping the "Fast" button and let the belt gradually increase in speed and took it up to 6.0. No problem! But...nobody wants to start each workout that slowly. I had a hunch it was 'fixed'. So, I stopped the treadmill and turned everything off. I started it again, selected "Manual", immediately hit the "2" then he "4" then the "6" on the right hand "Speed" panel, and it ran like new. No service call, no new speed sensor, no fiddling with the little 'diode', etc. Give this a try first...no need to even remove the motor cover. Best of luck!

On the sportcraft tx 455 E3 message is a broken speed sensor usually its plastic and breaks from the vibration
