One of the best ways to improve your schematic-reading troubleshooting mojo is to practice on relatively simple, familiar problems. When you flex your muscles on an easier issue, you’ll get stronger at the more complicated situations.
In this excursion into appliance repair excellence, the Samurai shows you how to troubleshoot a no-heat complaint on a Whirlpool-built electric dryer, a scenario most techs are familiar with. He uses this common problem to illustrate other troubleshooting skills such as shifting from the nice, pretty lines on the schematic to the tangly-gangly mess of wires inside the appliance. This is the high-dollah skill that takes training and practice to develop, it doesn’t just come “naturally.”
Topics covered in this video:
- Selecting a load of interest and then using the schematic as our troubleshooting planning document where we decide what electrical measurements we’ll make and at what physical locations on the appliance.
- Jumping out a switch that has failed open as a way of testing the load of interest and its power supply circuit
- A demonstration of the difference in readings between LoZ and VAC with a little twist on LoZ.
- The under-loved-but-almighty amp measurement– how to make them and how to use it in troubleshooting.
