Troubleshooting a GE Range using the Tech Sheet: Webinar Excerpt

Posted on May 11, 2016 by - Tech Talk

This excerpt from our regular Monday evening Office Hours webinars is just one of the three appliance tech sheets we used to develop troubleshooting strategies for specific problems with the appliances. These regular, live events are a free benefit for MST Academy students and Professional Appliantologist members at

In this video excerpt, we are troubleshooting a problem with a GE JSP47BF4 glass cooktop range where one of the hot surface indicator lights stays on even when the element switch is off and the element is at room temperature. We used the tech sheet (minimanual) for this model to understand the circuit and developed a couple of specific troubleshooting strategies.

The analytical principles demonstrated in this video apply to ALL appliances. Electricity works the same way in every appliance no matter who made it. Understanding circuits and reading schematics are powerful skills with broad application that will take your appliance repair troubleshooting to the next level-- increasing first call completes, profitability, and customer satisfaction. These are exactly the skills that we teach in the Fundamentals of Appliance Repair training course!

Clearing Up Capacitor Confusion for Appliance Repair Techs

Posted on April 22, 2016 by - Tech Talk

All capacitors are open circuits and, conversely, open circuits can be capacitors (for details on this, MST Academy students can watch the webinar recording on Voltage Measurements, Loading Meters, Ghost Voltages, and Triac-controlled Neutrals).

Most techs know that capacitors store a charge. Techs who have taken the Master Samurai Tech Fundamentals of Appliance Repair Course understand how they do this and also know that capacitors block direct current. But capacitors are also used in DC circuits. How can capacitors be used in DC circuits if they block direct current?

This short little Doodlecast should clear up your Capacitor Confusion!


Never fall prey to electrical confusion with our online appliance repair training courses at the Master Samurai Tech Academy.


Webinar Sample: Troubleshooting Appliances with Tech Sheets

Posted on April 14, 2016 by - Academy Talk, Tech Talk

MST Academy students have real-time access to the Samurai every Monday evening at our live webinar "Office Hours." Sometimes it is just an open Q & A, other times it's a presentation that dives deeper into an appliance technology topic.

One of our most popular webinar formats is Troubleshooting with Tech Sheets, where the Samurai simulates troubleshooting scenarios using actual tech sheets from several real appliances to show how to kick appliance bootay the Samurai Way!

Attendees get to interact along the way, offering up possible answers to the problem scenarios and asking questions of their own.When possible, we make a recording of the webinar available to those unlucky few who can't attend live.

We call these live training webinars Office Hours and they're held every Monday evening-- details on this page.

If you're curious about what goes on during Office Hours, here's a 16-minute sample from last Monday. It shows just one of the five tech sheets that were covered in the full webinar. But this is a good peek into the teachings of the Samurai and the life of a master appliance tech.



Gas Oven Hot Surface Ignition Systems – Technology and Troubleshooting

Posted on March 29, 2016 by - Academy Talk, Tech Talk

Most modern gas ovens use a carborundum ignitor to both control the gas valve and ignite the gas. Even though these are simple systems, I've found that many appliance technicians do not have a detailed understanding of how these systems work and, as a result, there's a lot "tech mythology" out there about how they fail.

This HOT webinar recording from an Office Hours webinar with Master Samurai Tech Academy students explains the theory of operation of these systems along with a detailed circuit analysis. I also explain some of the common failure modes and show an uncommon failure mode that can leave a gas bomb in your customer's home unless you know what you're looking for.

Our regular, live Office Hours webinars are one of the powerful, interactive features of being a student at the MST Academy. You get access to in-depth technical presentations such as this one as well as the opportunity to ask the Samurai any questions you have related to your coursework!
