Default Re: Treadmill Motor Control Board 032669-IF

I have repaired quite a lot of these over the years for customers and while I have had little success in tracking down service manuals they are generally straightforward enough to repair so long as you think of them as a smps which is essentially what they are with some logic. So in no particular order Bad solder joints, NTC, rectifier pack (usually caused by something else) electrolytic caps (the smaller ones), switching transistors, snubber caps, various relays are a weak spot and that goupy crap plastered around could do with going.

You really need to test this partly installed, hope some of this is useful and good luck with your board.

Hope this helps,
