When a split system heat pump won’t put out cool air, there may be several different reasons why. What will it take to find and fix the problem? Presented by Jim Johnson, an experienced trainer and HVAC/R electrical system repair expert, this video helps develop the troubleshooting know-how crucial to the job. A viewable/printable resource guide is available online and featured in the program to demonstrate the use of wiring diagrams. By following along with Jim as he performs the necessary diagram reading, viewers are able to identify all relevant components of the unit and isolate the malfunctioning part. A major part of this diagram-reading experience is establishing that the compressor is internally protected and that the diagram shows a single pole contact. In a detailed hands-on demo sequence, trainees learn how to use state-of-the-art tools and test equipment, including a digital multimeter for determining microfarad rating in run capacitors.
