Electrical Schematic Reading for HVAC

  • 8:00am-4:30pm

This course promotes the idea of troubleshooting and repair of systems using schematics and wiring diagrams.  With a focus on troubleshooting techniques and the concept of internal isolation, attendees participate in the recognition of components and circuits including diodes, capacitors, transformers, relays and more.  The latest in ANSI diagrams are discussed, which includes undersanting ladders, logic, keys and legends.  Circuit board technology in troubleshootin the system will also be discussed.  The course has 3 lab exercises using a schematic to identify faulty components, converting a line diagram to a schematic and making a schematic by tracing the system wires.  Other information about this course:

  • Identify common symbols, describe the use of a legend and sequence-of-operation and describe the operating sequence using a schematic wiring diagram
  • Cover the basic troubleshooting procedures to successfully isolate circuit problems using a refrigeration schematic wiring diagram.
  • Draw a line diagram for a piece of equipment and draw a schematic diagram from a line diagram.
  • Interpret drawings for a large rooftop air condditioner having electronic circuit boards and the ability to be accessed by a DDC system.

The Electrical Fundamentals class and the Electrical Troubleshooting classes are being held on the Tuesday and Wednesday prior; take all three classes for a more comprehensive Electrical Education!
