The treadmill will start and operate normally. Starting at slow speed and accepting keypad and hand-rest button commands to speed up. It also accepts the commands to slow down and the display is updated accordingly but the motor does not slow down. This is a Trojan treadmill with a B01-A6 speed controller board. I Checked the wiring at the motor, speed controller board and speed sensor. I also checked the speed sensor and all seems fine.

Use only a single-outlet surge suppressor that is
UL 1449 listed as a transient voltage surge suppressor
(TVSS). The surge suppressor must have a
UL suppressed voltage rating of 400 volts or less
and a minimum surge dissipation of 450 joules.
The surge suppressor must be electrically rated
for 120 volts AC and 15 amps. There must be a
monitoring light on the surge suppressor to indicate
whether it is functioning properly. Failure to
use a properly functioning surge suppressor could
result in damage to the control system of the
treadmill. If the control system is damaged, the
walking belt may change speed or stop unexpectedly,
which may result in a fall and serious injury.

If this is the same problem you had prior to replacing the MCB and speed sensor. I would check the drive motor, unplug unit then remove motor shroud then unplug the connectors leading to the motor itself. If you have wire leads and a 18v drill battery connect the leads into motor then attach the other end to you battery and if the motor will rotate ( approx. 1mph) , if it does the check speed sensor to see if the correct spacing between sensor and front roller ( check if the magnet has not fallen out of front roller pulley this also can cause you problems) hope this help!!

If speed ctrl LED is flickering and no DC output on motor spade then the motor control board is defective and needs to be replaced
SOURCE: my treadmill motor starts exactly
that a qualified technician check the motor controller board the mosfet (IRF250N.) or diodes

1) This error code has 2 options
a) Elevation Motor: a) lube the gear and shaft b) adjust the potentiomenter c) test the motor see my personal tips for help.
2) Display board: a) adjust the reed swithc , see the diagram attached, clean, tight the wires connector very well.
After you did the adjustment RUN the software calibration for diagnose and troubleshooting.
God bless you
Testimonial: "I cannot find my manual on the site :-( I have the original manual but this type of information is not displayed. I am not sure how to adjust the 'elevation motor' ? I still cannot see the magnet/reed switch on either the motor pulley or the front roller - are you sure all treadmills have these and might it not be built into the actual motor? The link to your "personal tips" does not take me to the correct page?"
