I have a Horizon Fitness TSC5 treadmill with very low usage. Have had
2 circuit boards fail on me now. The manufacturer says the treadmill
should be on a dedicated outlet. Would failure to do this cause the
circuit boards to fail? Also - since I have 2 of these expensive dead
circuit boards - is there a way to have them repaired? The
manufacturer doesn't repair them. Any help would be greatly
appreciated.

I'm not familiar with your particular treadmill, but if it's the motor
control board, then look for MOSFET failures. If the MOSFETs are
failing repeatedly, then look for a motor problem.

If you can post photos of your boards on your web space, then someone
may be able to help you.

Keep in mind that treadmills are large appliances and really should be
on dedicated, non-switched, non-GFI circuits (without anything else on
the same line). It is highly improbable that this is the main cause of
the problem. I hate to be the harbinger of bad news but Horizon
is not exactly top notch. Aside from that, unlike TVs and Microwaves
today that can take a good punch, fitness equipment in general are
very susceptible to things like power surges, low/high voltage and
brown outs. You should keep it unplugged when not in use. Assuming
its not power related worn or faulty parts may cause excessive strain
on the electronics. There are several possibilities, the most likely
being a worn out running belt and deck.
