Treadmill Sears Freespirit NO POWER...NEED HELP!

[[email protected]]

Hi, I own a Sears Freespirit treadmill model # 249306860 the console
doesn't power up and the mill doesn't turn. Can someone help? I want to
know if its the motor or the control board. I've opened it and there is
no burned smell, 120Vac is present and also have 124Vdc Output from the
control board. Can anyone help?
thanks

Do you have the manual. Some are availible online from the Sears
website.

Hi, no I don't have the manual and no specs either...
If you can find the service manual let me know.
or if there's anything I can try.
thanks

studio_1a:
I repaired a Sears threadmil a while ago. I think it was a ProForm
model or
something like that. It had a wrap-a-round heatsink around the control
board. Two of the 5 SCR's on the board were shorted or leakly.
Had to order them from Mouser Electronics. Replacing the SCRs
fixed the problem. It had a small separate board to control the incline
motor,
but that board was OK.
Hope this helps...

Why do you need a treadmill? I think your fat ass burned out the motor.

I finally got the manual from Taiwan but the schematic diagram for the
controller board is not in there. I know I'm supposed to get 20Vdc to
power up the console and not getting it, so I suspect perhaps some
voltage regulators blown. I checked all diodes and are good. I also
found a voltage regulator that was badly soldered by the previous owner
in the console cct board so it may have more than one problem. Which
way can the SCRs be tested?
thanks

SIMPLY, YOU'RE AN IDIOT!! THE MOTOR IS NOT BURNED OUT!!

3 terminal regulators are pretty easy to check, they'll shut down with
excessive load though so you might need to cut a trace temporarily on
the output pin if you have voltage going in but none out.

Google for datasheets for any parts you want to test, often that will
show you how to connect it if not a whole test circuit diagram.
