Many people mistakenly think that working on an electric dryer is easy Parts-changing-monkey work. Just swap out the part that isn't doing its thing, right?
Oh, no, my bruthahs and sistahs. Electric dryers can have interesting circuits that are fun to troubleshoot... if you know your stuff. If you can’t troubleshoot the electric circuits in these “low tech”, Old Skool appliances, how can you expect to troubleshoot the modern, computer-controlled appliances? We teach this in the Fundamentals course.
Both of the electric dryers in the video below wouldn't start. The causes were different, but in both cases we were able to find the exact failure by gazing upon the schematic diagrams and doing a few measurements from the control panel. Minimum disassembly, maximum bad-assery. This is the power of knowing basic electricity and circuits. Learn more, earn more!
This video demonstrates a powerful troubleshooting tool: Electrically Equivalent Points (EEPs). By identifying EEPs on the schematic, you can speed up your diagnosis and prevent unnecessary disassembly. Work smarter not harder!
In this short video, the Samurai demonstrates how understanding how sealed systems work and move heat can be used to make non-invasive diagnostics on refrigerator sealed systems. In this case, we're using a design criteria for condensers called "temperature split". This is the difference between the condenser's SATURATION temperature and the ambient temperature. Saturation is the key here because you don't want the superheated or sub cooled part of the condenser for your condenser temperature.
We teach sealed system thermodynamics, operation, troubleshooting, and repair in the Refrigerator Repair course at the Master Samurai Tech Academy. Self-paced, online, on-demand 24/7.
The Samurai and Mrs. Samurai share some highlights from the inaugural Appliantology Peer Group meeting. One of the topics discussed was the idea of doing electronic control board repairs as part of an appliance repair business.
