Understanding "Loading Down" in DC Power Supplies

Samurai Appliance Repair Man

1,103 views

If you've spent any time at the tech-only forums here at Appliantology, you've probably heard me refer to "loading down" as a failure mode that we encounter today in the field as appliance techs. Most techs are unaware of this as a failure mode and so end up replacing a control board when the problem was a bad DC load all along. This is part of the brave new digital world we live and work in today!

This little video gives a very simplistic explanation of what loading down is, how it manifests, and how to troubleshoot for it. Hope it helps!

Interesting- I was going for more the Salman Khan look. But Shel ain't too shabby.
