1. Powercycle the GE T2100 Treadmill and monitor the GE T2100
Treadmill for reoccurrence of this error. (This may be an isolated
incident.)
2. Check for loose wiring and connections between the drive
controller and the e-box.
3. Check for loose wiring and connections between the treadmill
and the host.
4. Check the terminal connections on the X1 connector on the
drive controller. See “Drive Controller X1 PIN descriptions” on
page 7-22.
5. Check the power board and processor board test points and
verify they are operating within the test range. See “Power
Supply Voltage Checks and Fuses” on page 6-27.
6. Replace the drive controller with a known working drive
controller. (If the problem persists...)
7. Replace the processor board. See “PCBs and Power Supply
Replacement” on page 7-28.

Measures power into the GE T2100 Treadmill.
1. Powercycle the GE T2100 Treadmill and monitor the GE T2100
Treadmill for reoccurrence of this error. (This error logs each
time the treadmill is powered off. This may be an isolated
incident.)
2. Check the fuses. See “Power Board Fuse Locations” on page 6-
29.
3. Check the power board and processor board test points and
verify they are operating within the test range. See “Power
Supply Voltage Checks and Fuses” on page 6-27.
4. Monitor AC power into the GE T2100 Treadmill. Watch for
inadequate power supply.
5. Replace the power board. See “PCBs and Power Supply
Replacement” on page 7-28. (If the problem persists...)
6. Replace the processor board. See “PCBs and Power Supply
Replacement” on page 7-28.
