Treadmill Sears Freespirit NO POWER...NEED HELP!
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 |

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... John |

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 wrote: studio_1a: I repaired a Sears threadmil a while ago. I think it was a ProForm model or something like that.
