We hope you enjoy this free webinar recording and that it helps make you a better appliance tech. This webinar will be available to the public for free through this month. After that, we'll remove this one and post a new free featured webinar recording selected from our vast repository of appliance repair training webinar recordings

If you're currently a professional appliance repair tech, these webinar recordings will improve your understanding of electric circuits and appliance technology and up your troubleshooting game. If you're a DIYer or considering getting into the appliance repair trade (great choice!), these webinar recordings will kick your training into high gear.

Now, on to the webinar! 


In this webinar, we uncovered the mysteries of voltage measurements and the huge difference between using a DMM vs. a loading meter. We talked about what ghost voltages are, how they are formed by capacitive coupling in AC circuits with open Neutrals, and how using a loading meter keeps you from getting head-faked by ghost voltages when measuring AC load voltages. We talked about triacs: what it means that they are current-controlled devices and why you need to be aware of this when you're testing an AC load circuit with a triac-controlled Neutral. We also showed how using a loading meter on these types of circuits is an elegant and fool-proof method for checking the triac.

Your webinar presenter is Scott M. Brown, PE. Scott earned two engineering degrees, a Bachelors from University of Georgia and a Masters from Clemson University, and has over ten years experience working as an engineer designing manufacturing processes, hazardous waste remediation systems, and industrial ammonia refrigeration systems. Additionally, he is a licensed Professional Engineer (PE) in the state of New Hampshire. Prior to beginning his university engineering studies, he was an avionics technician in the US Navy troubleshooting and repairing computer-controlled radar systems to the component level on control boards. He started doing appliance repair over 20 years ago for the fun of it and as a way to be self-employed.
