      [Webinar] Appliantology Workshop   11/09/2017

      Information is the name of the game in the appliance repair trade today. Appliantology is a powerful information tool for the professional appliance repair technician. But just like with any of the more capable tools in your tool bag, many of the more powerful features are hidden from you unless you "read the manual." Ugh! Who wants to do that? Well, this is one time when you don't have to! In this webinar, Team Samurai will personally walk you through the site and show you many of the useful and powerful features that even long-time users probably never knew existed.

The Master Samurai Tech Ten-Step Tango for Troubleshooting Appliances

Samurai Appliance Repair Man

1,121 views

Troubleshooting is the big missing skill among appliance techs today. This is the skill that distinguishes parts changing monkeys (PCMs) from Master Samurai Techs. It's the difference between a drunken street brawler making monkey jabs versus a trained MMA fighter making kill shots.

PCMs will thrash about wildly, monkey-jabbing at components hoping to get lucky and usually end up getting their asses kicked.

Anyone can monkey jab and the sad truth is that this is the dominant practice of the appliance repair trade today. It doesn't have to be that way. Anyone who wants to can learn how to make kill strikes like a Master Samurai Tech. 

Master Samurai Techs don't rely on luck. They have a plan of attack, a strategy. They deploy precision kill strikes that have been honed in the Dojo-- training at the Master Samurai Tech Academy and in the Office Hours webinars-- and systematically dominate the appliance. 

Whether you're troubleshooting a simple GE dryer with just a mechanical timer or a Sub-Zero refrigerator with a microcomputer board, multiple sub boards and two different compressor technologies, the troubleshooting procedure is the same. That's the Ten-Step Tango: a structured, disciplined procedure for solving problems. 

In our Office Hours webinars, we've begun a series of workshops on the Ten-Step Tango, applying it to different troubleshooting scenarios on real-world appliances. We started off by introducing the Ten-Step Tango procedure and then applied it to simple appliances (no control boards, just mechanical controls, like timers). Then, in the next workshop, we kicked it up a notch and troubleshot appliances with multiple control boards, digital communications, hoodoo, voodoo, and all kinda weird stuff. 

The workshop webinar recordings, along with all the other Office Hours webinar recordings, are available for Professional Appliantologists and Master Samurai Tech Academy students to watch at the links below:

The next workshop will be in January 2017 and will be announced here at Appliantology as well as in the MST-Appliantology newsletter.

Nice explanation, Samurai! Your old, boring, teachers at school tried to teach us all this: The Scientific Method.

Empiricism is the best way to work through unfamiliar territory, whether it be mathematics, mechanics, or chemistry...

affect one variable at a time, closing off the "blind-alleys" until all you are left with is the answer.

Hai! Gung-Ho! : AIM, DEPLOY, DESTROY!!!!!

Domo, Hiroshi. Yep, gotta have a system. Troubleshooting isn't pattern recognition or factoids, though it's often mistaken for these. Experienced techs can and definitely should draw on pattern recognition and factoids to get stuff fixed-- this is how they capitalize on their experience and get faster at common repairs. But these things are not much help when working on something new or "off the flowchart." Hopefully the Ten-Step Tango will provide some guidance and inspiration in those dark times.

Your 10-Step Tango for Trouble Shooting Appliances blog brought back memories of my years as a Technical Representative for a large sensors based industrial process control company.  Every industry has their PCM.  In my work history, I would be called into a plant at all hours of the day, often facing emotional customers and a PCM who has barricaded themselves behind a mountain of circuit boards, manuals and tools.  The only way out of the troubling-shooting disaster was to use a variation of the 10 step process - period. 

Final comment: After the Problem Statement I have found step two, which references documentation, is often bypassed with dire consequences for a successful outcome.

Domo, Samurai.

Thanks for your comments, jm! And you make a good point: the technical troubleshooting process is virtually the same no matter what equipment you're working on.
