Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, have you checked inside / wiring of the console?

Customer: replied 9 months ago.
all wires connected no pinched wires
Expert:  Louie replied 9 months ago.

Please provide a clear picture of the circuit board / connector inside the console as well as that of the other end to the motor controller are. Click HERE.

having trouble uploading pictures - working on it
Customer: replied 9 months ago.
directions for adding pictures does not match screen that I'm working in
Expert:  Louie replied 9 months ago.

I understand and when able please.

Customer: replied 9 months ago.
i am still getting error message
"We're sorry – an unknown error occurred. Please try again. ". Cannot attache pictures
Expert:  Louie replied 9 months ago.

If the picture exceeds 5MB, then the system would not allow upload.

Can you please check and/or reduce file size?

Customer: replied 9 months ago.
put them into PDF and reduced file size
Expert:  Louie replied 9 months ago.

Appreciate the pictures.

With "...Power light is on...", then it would likely be that power is reaching the console.

Have you considered / tried a HARD RESET ?

Customer: replied 9 months ago.
Nothing in manual about hard reset - how do you hard reset?
Expert:  Louie replied 9 months ago.

From the picture, there appears to be a 3V coin battery that powers the standby logic funstions. Removing this battery for an extended period of time would simulate a hard reset.

Would you be comfortable giving this a try?

Of course prescribed approach would be a conitnuity check of the wires using a multi-meter.

Customer: replied 9 months ago.
battery out, how long do I leave it out?
Expert:  Louie replied 9 months ago.

Say an hour or more with the unit also unplugged. The idea is dissipate over time residual power in the concolse circuitry.

Customer: replied 9 months ago.
OK battery out, treadmill unplugged will put back in after an hour
Expert:  Louie replied 9 months ago.

And would look forward to an update when able.

Customer: replied 9 months ago.
