Well-known industry author and instructor Jim Johnson is offering a new video for technicians who want to sharpen their troubleshooting skills.

"This HVAC training video program, is available in DVD format, is somewhat of a departure from what we’ve offered in the past," said Johnson. "It was produced specifically for technicians who really don’t need theory on electrical fundamentals, but want to know more about how to read schematic diagrams and then use them to track down the source of the problem in an HVAC/R system that’s down."

According to Johnson, "Using Schematics To Troubleshoot HVAC/R Electrical Circuits, Part 1" came about because of feedback from the industry. "It’s shorter than our fundamentals training videos, and the Technician’s Resource Guide contains only the diagrams and a short introduction of fill-in-the-blank information It doesn’t incorporate review questions and in-depth theory like our fundamentals programs do."

Johnson said his Tucson-based training firm, Technical Training Associates is offering this HVAC training video "in response to those who have used our fundamentals program and told us they want more, as well as those experienced technicians who have contacted us and suggested a shorter program focused only on schematic diagrams."

Covering transformers, thermostats, potential relays, capacitors, multi-speed motors, pressure switches, relays, and contactors, this program focuses on single-phase equipment and incorporates furnace, A/C and heat pump wiring diagrams. Other programs that cover three-phase equipment, magnetic starters, part winding start systems, and high and low voltage wiring for three-phase motors are planned for release at a later date.
