What You'll Learn

  • How to use timing charts with schematics to troubleshoot problems
  • How to use Ohm’s Law as a powerful troubleshooting tool
  • How to troubleshoot tricky open neutral problems
  • How to troubleshoot appliances with control boards, including multiple control and microprocessor boards

The course includes a challenging series of schematic lab exercises in which you will hone your schematic reading and troubleshooting skills.

The Final Step to Mastery

With Fundamentals and Refrigerator Repair under your belt, you’re well-equipped to handle most repair jobs. But take Advanced Troubleshooting and you’ll be able to handle all jobs well into the future.

This course takes a deep dive into the cutting-edge appliance troubleshooting techniques needed to repair newer electronic appliances. For example, in appliances with multiple control boards, you need to understand how to troubleshoot the microprocessor (main) board AND troubleshoot its communications with various sub-boards.

Sound complicated? It is. But that’s why appliance repair techs with these skills are indispensable and make the big bucks.


You must already have solid training in basic electricity, reading schematics, troubleshooting, and motors. Therefore, we strongly recommend starting your training with Fundamentals of Appliance Repair. If you’re not sure whether you need to take the prereq, take our quiz.
