Diagnostics 2 – Diagnosing 24 Heat Pump Residential Systems

Diagnosing 24 Heat Pump Residential Systems (troubleshooting calls with “You be the Technician” service calls homework) As the HVAC/R student acquires general knowledge about the components, circuits, and sequence of operations of various systems, a broad mental database is being created.

This pool of information, in effect, becomes a large “toolbox” that can be accessed as needed to help the technician solve various field problems. Just as a technician carries a complete set of hand tools, including wrenches, gauges, screwdrivers, and the like, a mental toolbox is just as important in order to troubleshoot an air-conditioning or heatpump system effectively. The commonsense aspect of troubleshooting helps the technician determine what to do with the available tools. Therefore, the more complete this tool-box is, the more effective the service technician will be.
