How to Decipher Schematics like a Pro!

Samurai Appliance Repair Man


In this journey to Total Appliance Enlightenment™ in a Live Dojo workshop, we worked on a real-world problem on a Kitchenaid refrigerator posted at Appliantology. We were interested in how the defrost timer motor gets Line and Neutral in both defrost and run modes. Turns out that doing so required that we also understand the rest of the circuit, including the dumbed "PC board". But how do we do that? That's exactly what we show you in this workshop recording! 

In this short little half hour video, Son of Samurai shows you the process of deciphering a schematic so you can figure out how your load of interest is supposed to get its power supply. He shows you how he used the schematic, specifications, the parts manual, and pictures of the parts all together to figure out how the entire electrical control of this refrigerator works. Along the way, you'll learn about the famous "loads in series" configuration and how a load can feed Neutral (or Line) to another load all by design.

Keep in mind, we did all this using only technical literature available to us on the web. This means you can do one helluva lotta prediagnosis before you even step foot in the house.

As you watch, focus on the process for figuring it out, not the answer. Understanding the process will empower you to figure out many of the electrical problems you face on service calls. Premium tech members at Appliantology and MST students may watch the video here
