The ability to troubleshoot heating, ventilation, air conditioning, and refrigeration (HVACR) equipment electrical problems is an important aspect of the HVACR technician’s role. Troubleshooting involves reading schematic and pictorial diagrams, interpreting the information to isolate the problem and conduct the appropriate tests, and then replacing the correct component. To be effective in achieving the ultimate goal of correct diagnosis, your learners will need a firm grasp of the fundamental concepts of electrical safety, basic electricity, and the proper use of test instruments.
By the end of this course, your learners will be able to do the following:
- Explain electrical power and the operating characteristics of equipment, circuits, motors, and control devices
- Use schematics to determine the expected operation of an electrical system
