Written and presented by Jim Johnson, this HVACR technician training course presents an overview of the fundamentals of schematic diagrams. With a firm understanding of the fundamentals of wiring diagrams and how symbols serve as a map of the electrical circuits in refrigeration and air conditioning systems, technicians can develop their troubleshooting skills.
This course includes information on the fundamental concepts of atomic theory and the basics of current flow, along with information on how understanding and applying that knowledge helps technicians master the concept of tracing circuits, and to understand how switches operate in series with the loads the control.
In addition to the DVD/video, this training package also includes a self-print CD containing an interactive, read-along resource guide, and a course exam consisting of multiple-choice questions and exercises that require the isolation and identification of specific circuits on a schematic diagram.
Technicians completing the course can send their exam for evaluation via regular mail or e-mail.
