This training tool is a module training program that is used to help teach HVAC/R Students how to troubleshoot heating and cooling control systems. It can be taught in a 4 hour block time frame or spread out over your whole lesson plan. It contains an Interactive Computer Program, Instructor’s Manual, Student Workbook, Student Assessment, PowerPoint Presentations and the Instructions on how to build Instructor and/or Student Hands-on Trainers. This module training program covers five areas of study; Symbols, Sequence of Operation, Series and Parallel Circuits, Relays (Coils and Contacts) and Troubleshooting. The Interactive Computer Program which is the heart of this training program uses a basic heating and cooling control ladder wiring diagram. The computer program takes that drawing and shows it in three different ways. In the Symbols Drawing it shows just the symbols used in the diagram and helps to teach symbol recognition. In the Whole Drawing the diagram is color coded to help teach difference of potential across controls. The diagram has buttons that can be clicked on for the disconnect, fan switch, and thermostat that makes the diagram change showing controls opening and closing, to help teach sequence of operation. In the Exploded Drawing we are able to explode out individual series circuits from the parallel circuits. The Exploded Drawing also is used to teach how relays are drawn in a ladder diagram where the coil is drawn in one place and the contacts are drawn in another place. By a click of the mouse you can show only the coil circuit and its contacts without the other components being shown on the diagram. This program combined with the Hands-On Trainers that you can build and the Instructor’s Manual and Student Workbook, you will find this a very useful training tool to help teach your students wiring troubleshooting.

About Our Business:

HVAC/R Productions was started in the beginning of 2008. But the HVAC Wiring Troubleshooting Trainer Program has been many years in the making. HVAC/R Productions is owner and operated by Don Crawshaw. Don has been in the HVAC industry both as a service technician, in charge of in-house training and as an instructor for Intellitec College in Colorado Springs. He has worked in the residential heating and air conditioning, commercial heating and air conditioning and supermarket commercial refrigeration for almost 30 years.

How was the HVAC Wiring Troubleshooting Trainer Program developed?

After studying test results of students after they had taken their benchmark, employment ready, exams I found that the scores were always lower in the wiring and troubleshooting areas. So, I designed these modules so the students could have better Hands-on training and designed the computer program to work with the interactive white board to make the wiring diagrams come to life. After years in the field I found out that this is also a problem with many service technicians that have been in the field for years.
