Free Short Course from the Master Samurai Tech Academy: The Ten Step Tango Troubleshooting Procedure

Troubleshooting is the big missing skill among appliance techs today. In fact, many techs don’t even know what troubleshooting is and mistake pattern recognition and factoids for real troubleshooting. Classical troubleshooting is a structured and scientific method for thinking and solving appliance problems. There is a method to the madness! The Master Samurai Tech troubleshooting method is called the Ten Step Tango (TST). There are specific dance steps to troubleshooting, and we teach

Gas Dryer Ignition Systems Webinar Recording

We went on a journey of wonder and discovery in last night's webinar and demystified those vexing gas dryer ignition systems. We learned how the two-stage gas valve works; how it is controlled by those three valve coils, a radiant sensor, and ignitor. We also learned what a "split coil" is and how it works. We also had an encounter with technical gremlins that attempted to thwart the Appliantological gospel but they were quickly slain. The recording also includes a good roll of the video I

Troubleshooting Gas Ovens like a Master Samurai Tech

In the last webinar, we put on our Master Samurai Tech hats and did a cleanup service call on a gas oven after a parts changing monkey (PCM) had already been out and failed to diagnose and repair the problem. We looked at what the PCM did on the service call as well as he did not do but should have done. We did a quick review of how hot surface ignition (HSI) systems work and how variations in supply voltage can affect the operation of these systems. Then we got inside the head of a Master Samur

The Smart Kitchen of Tomorrow is Here Today

I know from comments on my previous blog post on The Future of Appliance Repair: a Profession or an "Idiocracy"? that many appliance techs are bemoaning the increasing computerization of appliances. For most of these techs, it's because they have no idea how to troubleshoot them and so feel threatened. Many are even thinking, wishfully but incorrectly, that the increasing use of electronics in appliances is just a fad and will go away.  Nyet, tovarish!  Computers in appliances are not

The REAL New World Order is here!

Christ is risen from death and the rebellious sons of god (fallen angels) from Genesis 6:1-4 are judged and condemned (Psalm 82). The disinheritance from the Tower of Babel (Genesis 11 and Deuteronomy 32:8-9) is ended. The long exile of the 12 tribes is over. ALL people are freed from bondage, liberated from death and the power of demons, and all are called back into communion with the Most High God in the Messiah to be a new creation: the New Israel, a global Eden!   

Appliantology's Best Kept Secret: the Webinar Recordings Index Page

Y’all gather ‘round and ol’ Samurai’s gonna tell you about the best kept secret at Appliantology.  You know the Samurai does periodic webinars on a wide range of appliance repair topics.  At the webinars, we talk about all kinda cool techie topics like basic electric circuits, troubleshooting strategies and tactics, reading schematics, computer control and digital communications in appliances, electric motor operation, gas flame sensing and reignition technologies, and more. Over 30 ho

Webinar Recording for Office Hours, March 6, 2017

We talked about lots of good stuff last night at the Office Hours webinar. I started off with a brief presentation on Neutral and Ground in AC circuits, explaining how they are different and each serves different purposes in AC circuits.  Then we applied what we learned about power supplies in that presentation to decipher some crappy instructions in a service bulletin for a Whirlpool inverter microwave where we had to figure out how to test the digital data input to the inverter.  We

Annual Service Training Institute 2017 in San Diego

Had a great week at the Annual Service Training Institute (ASTI) in San Diego last week! Got to hang out with old friends as well as meet lots of Appliantologists and Master Samurai Tech students in-person for the first time. For technical training, I focused mostly on high-end appliances since that's about all that's worth fixing these days. Attended some technical training on Sub-Zero, Wolf, Bertazzoni, DCS, and a couple others, and some business courses.  I also conducted an all-day

The Master Samurai Tech Ten-Step Tango for Troubleshooting Appliances

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 o

New Personal Hygiene Appliance for Future Appliance Repairs

You old timers remember back in the day when we used to get service calls on scrotum scrubbers? Yeah, I was really glad when people stopped using those. Well, just when you thought the bad old days were gone for good, get ready, guys, because there's a new, even more disgusting personal hygiene appliance coming to the market that we'll be getting calls on: the butt wiper. Coming to a neighborhood near you:

The Future of Appliance Repair: a Profession or an "Idiocracy"?

We have a lot of moving parts at play in the appliance repair industry today. Over the past couple of decades, appliance technology has become much more complicated, yet technician troubleshooting skills have eroded. This creates some uncertainty about the direction our industry is going.  Are we going to be a profession, filled with well-paid, highly-skilled technicians at the top of their game, or a semi-skilled trade, filled with low-paid parts changers who are essentially just the eyes

Master Samurai Tech Academy Site Upgrade Today - Some Turbulence Expected

Good morning, ladies and gentlemen, this is your Samurai speaking. We're expecting a little turbulence today as we make some adjustments to the Master Samurai Tech Academy website. There may be periods throughout the day where the site either doesn't load at all or may look strange. This, too, shall pass.  For now, I invite you to sit back, relax, and peruse the latest pearls of appliantological wisdom in my blog here at Appliantology.

Are Samsung Appliances Reliable?

Samsung's in the news lately with exploding washers and tablet computers. So people may be wondering how reliable Samsung appliances are.  Here's a good article from the Yale Appliance blog comparing Samsung repair rates with industry averages. Yale Appliance and Lighting [website] is a large appliance dealer and service center in the Boston area. Yale completes over 20,000 service calls per year so I expect their results to be a good representation of reality.  One comment that caught my e

Sub-Zero Wolf Factory Training

I had the pleasure of attending Sub-Zero Wolf (SZW) factory training last week in Madison, WI. Flew in on Monday, training was Tuesday thru Thursday, and then flew out on Friday. The class consisted of 15 techs from around the country but also included a tech from Puerto Rico and another from Barbados. The techs included a few students from Master Samurai Tech and some Appliantology members.   This session was all Wolf products: gas and induction cooktops, gas and dual fuel ranges, vent hoo

Applying Circuit Fu Katas on a Whirlpool Electric Dryer Schematic

In this video, I use an old skool Whirlpool electric dryer to demonstrate electric circuit troubleshooting and analysis techniques. This is the ancient art of Circuit Fu. Although this is a simple circuit by today's standards, the principles and techniques can be used on any circuit because electricity works the same way. When you know basic electricity and circuits, you can decipher these diagrams and become a troubleshooting master...

Triac Operation for Appliance Techs

I wanted to give a more complete and accurate answer in this post.  To understand how triacs are turned off once they're turned on (and conducting) we need to

Troubleshooting and Repairing a Bosch Gas Range Surface Burner

No schematics on this one! I know that'll be a relief for some of you. Honestly, it was a nice break for me, too. I love these easy jobs where you can troubleshoot using only your eyeballs and fix it with something as simple as a paper clip.  In this short little video, I show you how to troubleshoot a problem with a surface burner on Bosch gas range. The burner was not lighting correctly and would sometimes flare up.  All gas range surface burners operate using the same principles so
