Do you know what "electrically equivalent points" are? Do you know how to recognize them on the schematic? Most importantly, do you know how to use them to avoid needlessly tearing down an appliance just so you can check a component?
In this expedition into appliance repair transcendence, Samurai Appliance Repair Man reveals more tricks and techniques for using the schematic to troubleshoot an electric dryer with no heat. Watch how I identify electrically equivalent points on the schematic and use them to diagnose the problem with the dryer with minimal disassembly. This is a simple example showing how using the schematic can save you time, aggravation, liability, and even personal injury. The principles illustrated here can be applied to any and all appliances IF you know how to read and use the schematic diagram.
Don't know how to read a schematic? We teach all about this in the Core Appliance Repair Training course.
The two criteria for electrically equivalent points are:
1. There is no measurable voltage difference between them and
2. They are in electrical continuity with each other.
A simple example of electrically equivalent points are two points along the same unbroken wire.
