Schematic Symbol Fundamentals and Translating What They Mean

Duration: 40 minutes

This HVACR technician program 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 program 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, this program also includes 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.
